# MagTag James Webb Telescope Status
## Overview
Danger:
Use your MagTag to show the current status of the James Webb telescope. NASA publishes this information to this [official status page.](https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html)
[This GitHub project](https://github.com/avatsaev/webb-tracker-api) provides a server application that can parse the status page and return the current data as JSON data. We will fetch the data updates from this server so that it's in an easy format for CircuitPython to consume.
This project will fetch the data and display it on the E-Ink screen using displayio Labels then put the MagTag into deep sleep mode to conserve the battery. It will awaken to refresh the data once per hour, or once per day. Use the reset button any time to immediately refresh it.

## Install CircuitPython
Danger: Make sure that you [update the TinyUF2 Bootloader](https://learn.adafruit.com/adafruit-magtag/update-tinyuf2-bootloader-for-circuitpython-10-4mb-boards-only) before installing CircuitPython!
### Adafruit MagTag - Update TinyUF2 Bootloader for CircuitPython 10 and Later
[Adafruit MagTag](https://learn.adafruit.com/adafruit-magtag)
[Update TinyUF2 Bootloader for CircuitPython 10 and Later](https://learn.adafruit.com/adafruit-magtag/update-tinyuf2-bootloader-for-circuitpython-10-4mb-boards-only)
[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** drive to iterate.
## Set Up CircuitPython
Follow the steps to get CircuitPython installed on your MagTag.
[CircuitPython Download for MagTag](https://circuitpython.org/board/adafruit_magtag_2.9_grayscale/)
Warning: WARNING: The updated Adafruit MagTag 2025 Edition will not work with CircuitPython 9.2.x or earlier. Make sure you install 10.x.x or later!
**Click the link above and download the latest .BIN and .UF2 file**
You can use a 9.x.x release for a pre-2025 MagTag. You **must** use a 10.x.x release for the updated MagTag 2025 Edition.
(depending on how you program the ESP32S2 board you may need one or the other, might as well get both)
Download and save it to your desktop (or wherever is handy).
Plug your MagTag 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.**
# Option 1 - Load with UF2 Bootloader
This is by far the easiest way to load CircuitPython. **However it requires your board has the UF2 bootloader installed. Some early boards do not (we hadn't written UF2 yet!) - in which case you can load using the built in ROM bootloader.**
Still, try this first!
Warning: Make sure that you [update the TinyUF2 Bootloader](https://learn.adafruit.com/adafruit-magtag/update-tinyuf2-bootloader-for-circuitpython-10-4mb-boards-only) before following these steps for the UF2 bootloader!
## Try Launching UF2 Bootloader
Loading CircuitPython by drag-n-drop UF2 bootloader is the easier way and we recommend it. If you have a MagTag where the front of the board is black, your MagTag came with UF2 already on it.
Launch UF2 by **double-clicking** the Reset button (the one next to the USB C port). You may have to try a few times to get the timing right.
If the UF2 bootloader is installed, you will see a new disk drive appear called **MAGTAGBOOT**
Copy the **UF2** file you downloaded at the first step of this tutorial onto the **MAGTAGBOOT** drive
If you're using Windows and you get an error at the end of the file copy that says **Error from the file copy, Error 0x800701B1: A device which does not exist was specified.** You can ignore this error, the bootloader sometimes disconnects without telling Windows, the install completed just fine and you can continue.[If its really annoying, you can also upgrade the bootloader (the latest version of the UF2 bootloader fixes this warning)](https://learn.adafruit.com/adafruit-magtag/install-uf2-bootloader)
Your board should auto-reset into CircuitPython, or you may need to press reset. A **CIRCUITPY** drive will appear. You're done! Go to the next pages.
# Option 2 - Use esptool to load BIN file
If you have an original MagTag with while soldermask on the front, we didn't have UF2 written for the ESP32S2 yet so it will not come with the UF2 bootloader.
You can upload with **esptool** to the ROM (hardware) bootloader instead!
Follow the initial steps found in the [Run esptool and check connection section of the ROM Bootloader page](https://learn.adafruit.com/adafruit-magtag/rom-bootloader#run-esptool-and-check-connection-3076823-5) to verify your environment is set up, your board is successfully connected, and which port it's using.
**In the final command to write a binary file to the board, replace the port with your port, and replace "firmware.bin" with the the file you downloaded above.**
The output should look something like the output in the image.
Press reset to exit the bootloader.
Your **CIRCUITPY** drive should appear!
You're all set! Go to the next pages.
# Option 3 - Use Chrome Browser To Upload BIN file
If for some reason you cannot get esptool to run, you can always try using the Chrome-browser version of esptool we have written. This is handy if you don't have Python on your computer, or something is really weird with your setup that makes esptool not run (which happens sometimes and isn't worth debugging!) You can follow along on the [Web Serial ESPTool](https://learn.adafruit.com/adafruit-magtag/web-serial-esptool) page and either load the UF2 bootloader and then come back to Option 1 on this page, or you can download the CircuitPython BIN file directly using the tool in the same manner as the bootloader.

## CircuitPython Internet Test
One of the great things about most Espressif microcontrollers are their built-in WiFi capabilities. This page covers the basics of getting connected using CircuitPython.
The first thing you need to do is update your **code.py** to the following (it will error until WiFi details are added). Click the **Download Project Bundle** button to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, and copy the **entire** **lib** **folder** and the **code.py** file to your **CIRCUITPY** drive.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/ESP32_S2_WiFi_Tests/CPy_Native_WiFi_Test/code.py
Your **CIRCUITPY** drive should resemble the following.
To get connected, the next thing you need to do is update the **settings.toml** file.
## The settings.toml File
We expect people to share tons of projects as they build CircuitPython WiFi widgets. What we want to avoid is people accidentally sharing their passwords or secret tokens and API keys. So, we designed all our examples to use a **settings.toml** file, that is on your **CIRCUITPY** drive, to hold secret/private/custom data. That way you can share your main project without worrying about accidentally sharing private stuff.
If you have a fresh install of CircuitPython on your board, the initial **settings.toml** file on your **CIRCUITPY** drive is empty.
To get started, you can update the **settings.toml** on your **CIRCUITPY** drive to contain the following code.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/ESP32_S2_WiFi_Tests/CPy_Native_WiFi_Test/settings.toml
This file should contain a series of Python variables, each assigned to a string. Each variable should describe what it represents (say `wifi_ssid`), followed by an **= ** (equals sign), followed by the data in the form of a Python string (such as `"my-wifi-password"` including the quote marks).
**At a minimum you'll need to add/update your WiFi SSID and WiFi password, so do that now!**
As you make projects you may need more tokens and keys, just add them one line at a time. See for example other tokens such as one for accessing GitHub or the Hackaday API. Other non-secret data like your timezone can also go here.
For the correct time zone string, look at [http://worldtimeapi.org/timezones](http://worldtimeapi.org/timezones) and remember that if your city is not listed, look for a city in the same time zone, for example Boston, New York, Philadelphia, Washington DC, and Miami are all on the same time as New York.
Of course, don't share your **settings.toml** - keep that out of GitHub, Discord or other project-sharing sites.
Warning:
If you connect to the serial console, you should see something like the following:
In order, the example code...
Checks the ESP32's MAC address.
```python
print(f"My MAC address: {[hex(i) for i in wifi.radio.mac_address]}")
```
Performs a scan of all access points and prints out the access point's name (SSID), signal strength (RSSI), and channel.
```python
print("Available WiFi networks:")
for network in wifi.radio.start_scanning_networks():
print("\t%s\t\tRSSI: %d\tChannel: %d" % (str(network.ssid, "utf-8"),
network.rssi, network.channel))
wifi.radio.stop_scanning_networks()
```
Connects to the access point you defined in the **settings.toml** file, and prints out its local IP address.
```python
print(f"Connecting to {os.getenv('WIFI_SSID')}")
wifi.radio.connect(os.getenv("WIFI_SSID"), os.getenv("WIFI_PASSWORD"))
print(f"Connected to {os.getenv('WIFI_SSID')}")
print(f"My IP address: {wifi.radio.ipv4_address}")
```
Attempts to ping a Google DNS server to test connectivity. If a ping fails, it returns `None`. Initial pings can sometimes fail for various reasons. So, if the initial ping is successful (`is not None`), it will print the echo speed in ms. If the initial ping fails, it will try one more time to ping, and then print the returned value. If the second ping fails, it will result in `"Ping google.com: None ms"` being printed to the serial console. Failure to ping does not always indicate a lack of connectivity, so the code will continue to run.
```python
ping_ip = ipaddress.IPv4Address("8.8.8.8")
ping = wifi.radio.ping(ip=ping_ip) * 1000
if ping is not None:
print(f"Ping google.com: {ping} ms")
else:
ping = wifi.radio.ping(ip=ping_ip)
print(f"Ping google.com: {ping} ms")
```
The code creates a socketpool using the wifi radio's available sockets. This is performed so we don't need to re-use sockets. Then, it initializes a a new instance of the [requests](http://docs.python-requests.org/en/master/) interface - which makes getting data from the internet _really really easy._
```python
pool = socketpool.SocketPool(wifi.radio)
requests = adafruit_requests.Session(pool, ssl.create_default_context())
```
To read in plain-text from a web URL, call `requests.get` - you may pass in either a http, or a http **s** url for SSL connectivity.
```python
print(f"Fetching text from {TEXT_URL}")
response = requests.get(TEXT_URL)
print("-" * 40)
print(response.text)
print("-" * 40)
```
Requests can also display a JSON-formatted response from a web URL using a call to `requests.get`.
```python
print(f"Fetching json from {JSON_QUOTES_URL}")
response = requests.get(JSON_QUOTES_URL)
print("-" * 40)
print(response.json())
print("-" * 40)
```
Finally, you can fetch and parse a JSON URL using `requests.get`. This code snippet obtains the `stargazers_count` field from a call to the GitHub API.
```python
print(f"Fetching and parsing json from {JSON_STARS_URL}")
response = requests.get(JSON_STARS_URL)
print("-" * 40)
print(f"CircuitPython GitHub Stars: {response.json()['stargazers_count']}")
print("-" * 40)
```
OK you now have your ESP32 board set up with a proper **settings.toml** file and can connect over the Internet. If not, check that your **settings.toml** file has the right SSID and password and retrace your steps until you get the Internet connectivity working!
## IPv6 Networking
Starting in CircuitPython 9.2, IPv6 networking is available on most Espressif wifi boards. Socket-using libraries like **adafruit\_requests** and **adafruit\_ntp** will need to be updated to use the new APIs and for now can only connect to services on IPv4.
### IPv6 connectivity & privacy
IPv6 addresses are divided into many special kinds, and many of those kinds (like those starting with **FC** , **FD** , **FE** ) are private or local; Addresses starting with other prefixes like **2002:** and **2001:** are globally routable. In 2024, far from all ISPs and home networks support IPv6 internet connectivity. For more info consult resources like [Wikipedia](https://en.wikipedia.org/wiki/IPv6_address#Local_addresses). If you're interested in global IPv6 connectivity you can use services like [Hurricane Electric](https://www.he.net/) to create an "IPv6 tunnel" (free as of 2024, but requires expertise and a compatible router or host computer to set up)
It's also important to be aware that, as currently implemented by Espressif, there are privacy concerns especially when these devices operate on the global IPv6 network: The device's unique identifier (its EUI-64 or MAC address) is used by default as part of its IPv6 address. This means that the device identity can be tracked across multiple networks by any service it connects to.
### Enable IPv6 networking
Due to the privacy consideration, IPv6 networking is not automatically enabled. Instead, it must be explicitly enabled by a call to `start_dhcp_client` with the `ipv6=True` argument specified:
```python
wifi.start_dhcp_client(ipv6=True)
```
### Check IP addresses
The read-only `addresses` property of the `wifi.radio` object holds all addresses, including IPv4 and IPv6 addresses:
```python
>>> wifi.radio.addresses
('FE80::7EDF:A1FF:FE00:518C', 'FD5F:3F5C:FE50:0:7EDF:A1FF:FE00:518C', '10.0.3.96')
```
The `wifi.radio.dns` servers can be IPv4 or IPv6:
```python
>>> wifi.radio.dns
('FD5F:3F5C:FE50::1',)
>>> wifi.radio.dns = ("1.1.1.1",)
>>> wifi.radio.dns
('1.1.1.1',)
```
### Ping v6 networks
`wifi.radio.ping` accepts v6 addresses and names:
```python
>>> wifi.radio.ping("google.com")
0.043
>>> wifi.radio.ping("ipv6.google.com")
0.048
```
### Create & use IPv6 sockets
Use the address family `socket.AF_INET6`. After the socket is created, use methods like `connect`, `send`, `recfrom_into`, etc just like for IPv4 sockets. This code snippet shows communicating with a private-network NTP server; this IPv6 address will not work on your network:
```python
>>> ntp_addr = ("fd5f:3f5c:fe50::20e", 123)
>>> PACKET_SIZE = 48
>>>
>>> buf = bytearray(PACKET_SIZE)
>>> with socket.socket(socket.AF_INET6, socket.SOCK_DGRAM) as s:
... s.settimeout(1)
... buf[0] = 0b0010_0011
... s.sendto(buf, ntp_addr)
... print(s.recvfrom_into(buf))
... print(buf)
...
48
(48, ('fd5f:3f5c:fe50::20e', 123))
bytearray(b'$\x01\x03\xeb\x00\x00\x00\x00\x00\x00\x00GGPS\x00\xeaA0h\x07s;\xc0\x00\x00\x00\x00\x00\x00\x00\x00\xeaA0n\xeb4\x82-\xeaA0n\xebAU\xb1')
```
# MagTag James Webb Telescope Status
## Project Files
Plug your MagTag into your computer via a known good USB C power and data cable. The MagTag should show up in your computer File Explorer/Finder (depending on your operating system) ad a flash drive named **CIRCUITPY**.
Download the project files with the Download Project Bundle button in the code window below. Unzip and copy/paste the **code.py** , lib files and font files to your **CIRCUITPY** drive.
After copying your drive should look like this. It can contain other files as well, but must contain these at a minimum:
## Code
The program code is shown below:
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/MagTag/MagTag_Webb_Telescope_Status/code.py
# MagTag James Webb Telescope Status
## Code Walk-Through
## Run Once Then Sleep
This project code does not contain a main loop section. Instead it's written such that it will run once, fetch the data, show it on the eInk display and then put the MagTag into deep sleep for either one hour or one day. If there is any problem during the data fetching it will restart the MagTag after a few seconds to try everything once again.
When the MagTag wakes up from deep sleep, it will execute the script again from the beginning. For more information about sleeping see this guide: [Deep Sleep with CircuitPython](https://learn.adafruit.com/deep-sleep-with-circuitpython).
## Fetching Data
To fetch the current information about the Webb Telescope we use the [adafruit\_requests](https://github.com/adafruit/Adafruit_CircuitPython_Requests "Adafruit CircuitPython Requests") library. The script will make an HTTP GET request and receive back a string that contains the current JSON data.
## Displaying the Data
The data is displayed with displayio using Labels. The Labels containing units and other information are given a background color to contrast them from the Labels containing the data. All Labels are placed using anchored positioning. For more information about Labels and positioning see this guide: [CircuitPython Display\_Text Library](https://learn.adafruit.com/circuitpython-display_text-library)
## Refresh Carefully
The EInk display on the MagTag has a limit to how quickly it can be updated multiple times in succession. If an attempt to refresh too soon occurs the device will raise an exception. The project code guards against this by catching the error and trying again after waiting a suitable length of time.
## Further Detail
The project source code is commented thoroughly to explain what each portion of the code does. Read through the code and comments to gain more insight into how it operates.
