# PyPortal ISS Tracker ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/076/052/medium800/circuitpython_pp_iss_banner.jpg?1558743432) Where is the [International Space Station](https://en.wikipedia.org/wiki/International_Space_Station) (ISS) right now? Well, wherever it is, it won't be there for long. The ISS is always on the move and doing so very quickly. It goes all the way around the world in 1 and half hours (92.68 minutes). So by the time you look up its position, it's probably already somewhere else. This guide will show how you can use your PyPortal to get the current global location of the ISS and display it on top of a world map. The display will auto update. So by letting this program run, you can have a near real time display of the current location of the ISS. Let's get started. ![](https://cdn-learn.adafruit.com/assets/assets/000/075/669/medium800/circuitpython_iss_banner.jpg?1557795681) # PyPortal ISS Tracker ## Install CircuitPython [CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY**  "flash" drive to iterate. The following instructions will show you how to install CircuitPython. If you've already installed CircuitPython but are looking to update it or reinstall it, the same steps work for that as well! ## Set up CircuitPython Quick Start! Follow this quick step-by-step for super-fast Python power :) [Download the latest version of CircuitPython for the PyPortal via CircuitPython.org](https://circuitpython.org/board/pyportal/) [Download the latest version of CircuitPython for the PyPortal Pynt via CircuitPython.org](https://circuitpython.org/board/pyportal_pynt/) **Click the link above to download the latest version of CircuitPython for the PyPortal.** Download and save it to your desktop (or wherever is handy). ![circuitpython_pyportal-uf2.png](https://cdn-learn.adafruit.com/assets/assets/000/073/615/medium640/circuitpython_pyportal-uf2.png?1553610968) Plug your PyPortal into your computer using a known-good USB cable. **A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.** Double-click the **Reset** button on the top in the middle (magenta arrow) on your board, and you will see the NeoPixel RGB LED (green arrow) turn green. If it turns red, check the USB cable, try another USB port, etc.  **Note:** The little red LED next to the USB connector will pulse red. That's ok! If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right! ![circuitpython_PyPortalResetNeoPIxel.jpg](https://cdn-learn.adafruit.com/assets/assets/000/071/993/medium640/circuitpython_PyPortalResetNeoPIxel.jpg?1551213425) You will see a new disk drive appear called **PORTALBOOT**. Drag the **adafruit-circuitpython-pyportal-\.uf2** file to **PORTALBOOT.** ![circuitpython_PyPortal_PORTALBOOT.png](https://cdn-learn.adafruit.com/assets/assets/000/072/029/medium640/circuitpython_PyPortal_PORTALBOOT.png?1551287972) ![circuitpython_PyPortal_Drag_UF2.png](https://cdn-learn.adafruit.com/assets/assets/000/072/030/medium640/circuitpython_PyPortal_Drag_UF2.png?1551287983) The LED will flash. Then, the **PORTALBOOT** drive will disappear and a new disk drive called **CIRCUITPY** will appear. If you haven't added any code to your board, the only file that will be present is **boot\_out.txt**. This is absolutely normal! It's time for you to add your **code.py** and get started! That's it, you're done! :) ![circuitpython_PyPortalCIRCUITPY.png](https://cdn-learn.adafruit.com/assets/assets/000/071/995/medium640/circuitpython_PyPortalCIRCUITPY.png?1551213875) ## PyPortal Default Files Click below to download a zip of the files that shipped on the PyPortal or PyPortal Pynt. [PyPortal Default Files](https://github.com/adafruit/circuitpython-default-files/tree/main/boards/pyportal/4.x) [PyPortal Pynt Default Files](https://github.com/adafruit/circuitpython-default-files/tree/main/boards/pyportal_pynt/5.x) # PyPortal ISS Tracker ## PyPortal CircuitPython Setup To use all the amazing features of your PyPortal with CircuitPython, you must first install a number of libraries. This page covers that process. # Adafruit CircuitPython Bundle Download the Adafruit CircuitPython Library Bundle. You can find the latest release here: [Latest Adafruit CircuitPython Library Bundle](https://circuitpython.org/libraries) Download the **adafruit-circuitpython-bundle-\*.x-mpy-\*.zip** bundle zip file where **\*.x MATCHES THE VERSION OF CIRCUITPYTHON YOU INSTALLED** , and unzip a folder of the same name. Inside you'll find a **lib** folder. You have two options: - You can add the **lib** folder to your **CIRCUITPY** drive. This will ensure you have _all the drivers_. But it will take a bunch of space on the 8 MB disk - Add each library as you need it, this will reduce the space usage but you'll need to put in a little more effort. At a minimum we recommend the following libraries, in fact we more than recommend. They're basically required. So grab them and install them into **CIRCUITPY/lib** now! - **adafruit\_esp32spi** - This is the library that gives you internet access via the ESP32 using (you guessed it!) SPI transport. You need this for anything Internet - **adafruit\_requests** - This library allows us to perform HTTP requests and get responses back from servers. GET/POST/PUT/PATCH - they're all in here! - adafruit\_connection\_manager - used by adafruit\_requests. - **adafruit\_pyportal** - This is our friendly wrapper library that does a lot of our projects, displays graphics and text, fetches data from the internet. Nearly all of our projects depend on it! - **adafruit\_portalbase**  - This library is the base library that adafruit\_pyportal library is built on top of. - **adafruit\_touchscreen** - a library for reading touches from the resistive touchscreen. Handles all the analog noodling, rotation and calibration for you. - **adafruit\_io** - this library helps connect the PyPortal to our free datalogging and viewing service - **adafruit\_imageload** - an image display helper, required for any graphics! - **adafruit\_display\_text** - not surprisingly, it displays text on the screen - **adafruit\_bitmap\_font** - we have fancy font support, and its easy to make new fonts. This library reads and parses font files. - **adafruit\_slideshow** - for making image slideshows - handy for quick display of graphics and sound - **neopixel** - for controlling the onboard neopixel - **adafruit\_adt7410** - library to read the temperature from the on-board Analog Devices ADT7410 precision temperature sensor (not necessary for Titano or Pynt) - **adafruit\_bus\_device** - low level support for I2C/SPI - **adafruit\_fakerequests**  - This library allows you to create fake HTTP requests by using local files. # PyPortal ISS Tracker ## Create Your settings.toml File CircuitPython works with WiFi-capable boards to enable you to make projects that have network connectivity. This means working with various passwords and API keys. As of [CircuitPython 8](https://circuitpython.org/downloads), there is support for a **settings.toml** file. This is a file that is stored on your **CIRCUITPY** drive, that contains all of your secret network information, such as your SSID, SSID password and any API keys for IoT services. It is designed to separate your sensitive information from your **code.py** file so you are able to share your code without sharing your credentials. CircuitPython previously used a **secrets.py** file for this purpose. The **settings.toml** file is quite similar. Warning: Your **settings.toml** file should be stored in the main directory of your **CIRCUITPY** drive. It should not be in a folder. ## CircuitPython **settings.toml** File This section will provide a couple of examples of what your **settings.toml** file should look like, specifically for CircuitPython WiFi projects in general. The most minimal **settings.toml** file must contain your WiFi SSID and password, as that is the minimum required to connect to WiFi. Copy this example, paste it into your **settings.toml** , and update: - `your_wifi_ssid` - `your_wifi_password` ```auto CIRCUITPY_WIFI_SSID = "your_wifi_ssid" CIRCUITPY_WIFI_PASSWORD = "your_wifi_password" ``` Many CircuitPython network-connected projects on the Adafruit Learn System involve using Adafruit IO. For these projects, you must _also_ include your Adafruit IO username and key. Copy the following example, paste it into your settings.toml file, and update: - `your_wifi_ssid` - `your_wifi_password` - `your_aio_username` - `your_aio_key` ```auto CIRCUITPY_WIFI_SSID = "your_wifi_ssid" CIRCUITPY_WIFI_PASSWORD = "your_wifi_password" ADAFRUIT_AIO_USERNAME = "your_aio_username" ADAFRUIT_AIO_KEY = "your_aio_key" ``` Some projects use different variable names for the entries in the **settings.toml** file. For example, a project might use `ADAFRUIT_AIO_ID` in the place of `ADAFRUIT_AIO_USERNAME`. **If you run into connectivity issues, one of the first things to check is that the names in the settings.toml file match the names in the code.** Warning: Not every project uses the same variable name for each entry in the **settings.toml** file! Always verify it matches the code. ## **settings.toml** File Tips Here is an example **settings.toml** file. ```auto # Comments are supported CIRCUITPY_WIFI_SSID = "guest wifi" CIRCUITPY_WIFI_PASSWORD = "guessable" CIRCUITPY_WEB_API_PORT = 80 CIRCUITPY_WEB_API_PASSWORD = "passw0rd" test_variable = "this is a test" thumbs_up = "\U0001f44d" ``` In a **settings.toml** file, it's important to keep these factors in mind: - Strings are wrapped in double quotes; ex: `"your-string-here"` - Integers are _ **not** _ quoted and may be written in decimal with optional sign (`+1`, `-1`, `1000`) or hexadecimal (`0xabcd`). - Floats (decimal numbers), octal (`0o567`) and binary (`0b11011`) are not supported. - Use `\u` escapes for weird characters, `\x` and `\ooo` escapes are not available in **.toml** files - Example: `\U0001f44d` for 👍 (thumbs up emoji) and `\u20ac` for € (EUR sign) - Unicode emoji, and non-ASCII characters, stand for themselves as long as you're careful to save in "UTF-8 without BOM" format     When your  **settings.toml ** file is ready, you can save it in your text editor with the **.toml**  extension. ![adafruit_products_dotToml.jpg](https://cdn-learn.adafruit.com/assets/assets/000/117/071/medium640/adafruit_products_dotToml.jpg?1671034293) ## Accessing Your **settings.toml** Information in **code.py** In your **code.py** file, you'll need to `import` the `os` library to access the **settings.toml** file. Your settings are accessed with the `os.getenv()` function. You'll pass your settings entry to the function to import it into the **code.py** file. ```python import os print(os.getenv("test_variable")) ``` ![](https://cdn-learn.adafruit.com/assets/assets/000/117/072/medium800/adafruit_products_tomlOutput.jpg?1671034496) In the upcoming CircuitPython WiFi examples, you'll see how the **settings.toml ** file is used for connecting to your SSID and accessing your API keys. # PyPortal ISS Tracker ## Internet Connect! # Connect to WiFi OK, now that you have your  **settings.toml** file set up - you can connect to the Internet. To do this, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script. Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive. Your **CIRCUITPY** drive should now look similar to the following image: ![CIRCUITPY](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/esp32spi_esp32spi_simpletest.py.png ) Info: Update to CircuitPython 9.2.x or later to use this example. https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_simpletest.py And save it to your board, with the name **code.py**. Don't forget you'll also need to create the **settings.toml** file as seen above, with your WiFi ssid and password. In a serial console, you should see something like the following. For more information about connecting with a serial console, view the guide [Connecting to the Serial Console](https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console). ```terminal >>> import wifitest ESP32 SPI webclient test ESP32 found and in idle mode Firmware vers. 1.7.5 MAC addr: 24:C9:DC:BD:0F:3F HomeNetwork RSSI: -46 HomeNetwork RSSI: -76 Fios-12345 RSSI: -92 FiOS-AB123 RSSI: -92 NETGEAR53 RSSI: -93 Connecting to AP... Connected to HomeNetwork RSSI: -45 My IP address is 192.168.1.245 IP lookup adafruit.com: 104.20.39.240 Ping google.com: 30 ms Fetching text from http://wifitest.adafruit.com/testwifi/index.html ---------------------------------------- This is a test of Adafruit WiFi! If you can read this, its working :) ---------------------------------------- Fetching json from http://wifitest.adafruit.com/testwifi/sample.json ---------------------------------------- {'fun': True, 'company': 'Adafruit', 'founded': 2005, 'primes': [2, 3, 5], 'pi': 3.14, 'mixed': [False, None, 3, True, 2.7, 'cheese']} ---------------------------------------- Done! ``` Going over the example above, here's a breakdown of what the program is doing: - Initialize the ESP32 over SPI using the SPI port and 3 control pins: ```python esp32_cs = DigitalInOut(board.ESP_CS) esp32_ready = DigitalInOut(board.ESP_BUSY) esp32_reset = DigitalInOut(board.ESP_RESET) #... else: spi = busio.SPI(board.SCK, board.MOSI, board.MISO) esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset) ``` - Get the socket pool and the SSL context, and then tell the `adafruit_requests` library about them. ```python pool = adafruit_connection_manager.get_radio_socketpool(esp) ssl_context = adafruit_connection_manager.get_radio_ssl_context(esp) requests = adafruit_requests.Session(pool, ssl_context) ``` - Verify an ESP32 is found, checks the firmware and MAC address ```auto if esp.status == adafruit_esp32spi.WL_IDLE_STATUS: print("ESP32 found and in idle mode") print("Firmware vers.", esp.firmware_version) print("MAC addr:", ":".join("%02X" % byte for byte in esp.MAC_address)) ``` - Perform a scan of all access points it can see and print out the name and signal strength. ```python for ap in esp.scan_networks(): print("\t%-23s RSSI: %d" % (ap.ssid, ap.rssi)) ``` - Connect to the AP we've defined here, then print out the local IP address. Then attempt to do a domain name lookup and ping google.com to check network connectivity. (Note sometimes the ping fails or takes a while; this isn't a big deal.) ```python print("Connecting to AP...") while not esp.is_connected: try: esp.connect_AP(ssid, password) except OSError as e: print("could not connect to AP, retrying: ", e) continue print("Connected to", esp.ap_info.ssid, "\tRSSI:", esp.ap_info.rssi) print("My IP address is", esp.ipv4_address) print( "IP lookup adafruit.com: %s" % esp.pretty_ip(esp.get_host_by_name("adafruit.com")) ) ``` Now we're getting to the really interesting part of the example program. We've written a library for web fetching web data, named [adafruit\_requests](https://github.com/adafruit/Adafruit_CircuitPython_Requests). It is a lot like the regular Python library named [requests](https://requests.readthedocs.io/en/latest/). This library allows you to send HTTP and HTTPS requests easily and provides helpful methods for parsing the response from the server. - Here is the part of the example program is fetching text data from a URL. ```python TEXT_URL = "http://wifitest.adafruit.com/testwifi/index.html" # Further up in the program # ... print("Fetching text from", TEXT_URL) r = requests.get(TEXT_URL) print('-' * 40) print(r.text) print('-' * 40) r.close() ``` - Finally, here the program is fetching some JSON data. The `adafruit_requests` library will parse the JSON into a Python dictionary whose structure is the same as the structure of the JSON. ```auto JSON_URL = "http://wifitest.adafruit.com/testwifi/sample.json" # Further up in the program # ... print("Fetching json from", JSON_URL) r = requests.get(JSON_URL) print('-' * 40) print(r.json()) print('-' * 40) r.close() ``` # Advanced Requests Usage Want to send custom HTTP headers, parse the response as raw bytes, or handle a response's http status code in your CircuitPython code? We've written an example to show advanced usage of the requests module below. To use with CircuitPython, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script. Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive. https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/main/examples/esp32spi/requests_esp32spi_advanced.py Your **CIRCUITPY** drive should now look similar to the following image: ![CIRCUITPY](https://adafruit.github.io/Adafruit_CircuitPython_Bundle/requests_esp32spi_requests_esp32spi_advanced.py.png ) # WiFi Manager The way the examples above connect to WiFi works but it's a little finicky. Since WiFi is not necessarily so reliable, you may have disconnects and need to reconnect. For more advanced uses, we recommend using the `WiFiManager` class. It will wrap the connection/status/requests loop for you - reconnecting if WiFi drops, resetting the ESP32 if it gets into a bad state, etc. Here's a more advanced example that shows using the `WiFiManager` and also how to fetch the current time from a web source. https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_localtime.py # Further Information For more information on the basics of doing networking in CircuitPython, see this guide: ### Networking in CircuitPython [Networking in CircuitPython](https://learn.adafruit.com/networking-in-circuitpython) # PyPortal ISS Tracker ## ISS Location Getting the current location of the ISS is actually super easy. There's a very simple [Open Notify API Server](http://api.open-notify.org/) which provides a couple of data sources: [Open Notify API Server](http://api.open-notify.org/) ![](https://cdn-learn.adafruit.com/assets/assets/000/075/571/medium800/circuitpython_Screenshot_from_2019-05-10_15-57-54.png?1557529094) The one we'll use is...you guessed it...the one called [**ISS Location Now**](http://api.open-notify.org/iss-now.json). That links to a simple JSON result which gives the current ISS location in terms of latitude and longitude. ![](https://cdn-learn.adafruit.com/assets/assets/000/075/573/medium800/circuitpython_Screenshot_from_2019-05-10_15-59-58.png?1557529210) The only problem is that latitude and longitude coordinates **(lat, lon)** describe the location in terms of a spherical coordinate system, since the Earth is round. We want to convert that to a 2D **(x, y)** location on a flat surface, like the PyPortal display. This is the realm of map projections. [There are quite a few](https://en.wikipedia.org/wiki/List_of_map_projections), a lot of which are not rectangular. We'll just stick with the classic [Mercator projection](https://en.wikipedia.org/wiki/Mercator_projection). ## Computing Screen Coordinates So how do we convert the **(lat, lon)** coordinates provided by the web service into **(x, y)** coordinates we can display on our PyPortal? It's basically the same math that is used in the map transform. You can find it for the Mercator projection on the [page linked above](https://en.wikipedia.org/wiki/Mercator_projection#Alternative_expressions). It's kind of buried in there with a bunch of others, but the main one to focus on is the one in terms of map width ( **W** ): ![](https://cdn-learn.adafruit.com/assets/assets/000/075/614/medium800/circuitpython_formula.png?1557548281) Instead of map width, this will be our display width. The other symbols are: - **W** = display width (320 for PyPortal) - **λ** = longitude in radians - **φ** = latitude in radians - **π** = Pi (a constant) We know our display width **W**. And **π** is a known constant (3.1415etc). The **λo** is just an offset for the horizontal origin. So then we can take any **(lat, lon) = (φ, λ)** pair and compute the corresponding **(x, y)** location for the PyPortal display. This [stackoverflow post](https://stackoverflow.com/a/14457180) also has some good information. ## Setting Up The Map The math above works almost all the way to the North and South poles. But the ISS has an orbital inclination of 51.6°, so we don't need to worry about latitudes above that. This works out nicely as it let's us crop our map a little at the top and bottom, which makes it fit better on the PyPortal display. So, let's get a map. The one used on the same Wikipedia page linked above will work fine. [Mercator Projection Map](https://commons.wikimedia.org/wiki/File:Mercator_projection_SW.jpg) And now we want to crop this map to fit the PyPortal screen, which is 320 x 240 pixels. You can do this in image manipulation software like Photoshop or Gimp. The red dashed rectangle below represents our crop which has an aspect ratio of 320:240 and uses the entire width of the map. ![](https://cdn-learn.adafruit.com/assets/assets/000/100/821/medium800/circuitpython_Mercator_projection_SW.jpg?1616454055) After cropping, we end up with this: ![](https://cdn-learn.adafruit.com/assets/assets/000/075/616/medium800/circuitpython_map_crop.jpg?1557550013) Then we just scale it so it's 320 x 240 pixels and save it as a BMP files so we can load it with the CircuitPython [displayio library](https://learn.adafruit.com/circuitpython-display-support-using-displayio/introduction). Here's the final file: [map.bmp](https://cdn-learn.adafruit.com/assets/assets/000/075/617/original/map.bmp?1557550093) # PyPortal ISS Tracker ## ISS Map Tracker Now that we know where to get the current **(lat, lon)** for the ISS and how to convert that to **(x, y)** we can write a little program to display this in near real time. The general idea for the program is pretty simple: - Load a background map ( **map.bmp** ) - Every ~10 seconds: - Get the current **(lat, lon)** location - Compute screen **(x, y)** from **(lat, lon)** - Draw a marker at **(x,y)** - Add location trail That's it. ## Download the Project Files Here's the complete code that does this. Click on the Download Project Bundle button to get all the files for this project: https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/PyPortal/PyPortal_ISS_Tracker/code.py Plug your PyPortal into your computer with a known good USB data+power cable. Copy all the files from the zip file on your computer to the PyPortal with the subdirectories noted below. Your PyPortal **CIRCUITPY** drive should contain the following files in the correct folders: ![CIRCUITPY](https://adafruit.github.io/Adafruit_Learning_System_Guides/PyPortal_PyPortal_ISS_Tracker.png ) # PyPortal ISS Tracker ## Customizing At the top of the code there is a section with some user changeable settings. It looks like this: ``` #--| USER CONFIG |-------------------------- MARK_SIZE = 10 # marker radius MARK_COLOR = 0xFF3030 # marker color MARK_THICKNESS = 5 # marker thickness TRAIL_LENGTH = 200 # trail length TRAIL_COLOR = 0xFFFF00 # trail color DATE_COLOR = 0x111111 # date color TIME_COLOR = 0x111111 # time color LAT_MAX = 80 # latitude (deg) of map top/bottom edge UPDATE_RATE = 10 # update rate in seconds #------------------------------------------- ``` You can change the general appearance of the circular marker using **MARK\_SIZE** , **MARK\_COLOR** , **MARK\_THICKNESS**. The trail can be adjusted with **TRAIL\_LENGTH** and **TRAIL\_COLOR**.The data and clock color can be changed with **DATE\_COLOR** and **CLOCK\_COLOR**. If you use a different map, you can adjust the vertical scaling by specifying the latitude (in degrees) of the upper and lower edges of the map with **LAT\_MAX**. The map used for this guide was cropped at about 80deg of latitude. You can also change the rate at which the web service is queried and the display is updated using **UPDATE\_RATE**. However, setting this to anything lower (faster) than the default 10 isn't recommended. There's no need to query the service any faster since the amount of pixels the marker will move in 10 seconds is pretty small. ## Featured Products ### AdaBox011 - PyPortal [AdaBox011 - PyPortal](https://www.adafruit.com/product/4061) Reach out beyond your desk - to the stars and beyond - with **PyPortal**!
