## 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 Twitter Display
## Twitter Auth Keys
Before we can use the Twitter API we need to register for a developer account.
Go to [https://developer.twitter.com/en.html](https://developer.twitter.com/en.html). You should see a page something very like:
Click apply:
Then **Apply for a developer account** :
Select **Exploring the API** and click **Next**.
Fill out the form that gets presented, and clock **Next**. Verify the information, and click **Next**. Agree to the terms, and click **Submit Application**.
A verification email will be sent to your Twitter account's email address. Respond accordingly and you'll be able to create your _app_.
## Creating an App
To access the Twitter API, you will need to create a Twitter app. On the Twitter Developer Portal, [navigate to the Projects & Apps page](https://developer.twitter.com/en/portal/projects-and-apps) and **click Create App**.
Name your app something unique.
After naming your app, you'll be presented with your keys and tokens. **Save all 3 keys and tokens somewhere safe** on your computer, such as a text file on your desktop.
Open the **secrets.py ** file on your PyPortal and add your Twitter app's Bearer token as `twitter_bearer_token`.
Your **secrets.py ** file should look like this:
```python
# This file is where you keep secret settings, passwords, and tokens!
# If you put them in the code you risk committing that info or sharing it
secrets = {
'ssid' : 'home ssid',
'password' : 'my password',
'timezone' : "America/New_York", # http://worldtimeapi.org/timezones
'github_token' : 'fawfj23rakjnfawiefa',
'hackaday_token' : 'h4xx0rs3kret',
'twitter_bearer_token' : 'YOUR_SECRET_TWITTER_BEARER_TOKEN'
}
```
# MagTag Twitter Display
## Code Usage
## Settings.toml Setup
Open the **settings.toml** file on your CircuitPython device using Mu or your favorite text editor. You're going to edit this file to enter the Twitter Bearer Token you saved earlier.
- **Change** ` twitter_bearer_token` to ** your app's Twitter bearer token**
Your **settings.toml** file should look like this:
```python
# This file is where you keep secret settings, passwords, and tokens!
# If you put them in the code you risk committing that info or sharing it
CIRCUITPY_WIFI_SSID="your-wifi-ssid"
CIRCUITPY_WIFI_PASSWORD="your-wifi-password"
timezone="America/New_York" # http://worldtimeapi.org/timezones
github_token="fawfj23rakjnfawiefa"
hackaday_token="h4xx0rs3kret"
twitter_bearer_token="YOUR_SECRET_TWITTER_BEARER_TOKEN"
```
## Installing Project Code
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 **MagTag\_Twitter/** 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:
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/MagTag/MagTag_Twitter/code.py
## Code Usage
Every 15 minutes, the MagTag will attempt to fetch and display a new tweet from the Twitter handler specified in the code.
Then it goes into a deep sleep mode for 15 minutes to save energy.
### Change the Twitter Handle
To display tweets from a specific Twitter account, change the following line in the code to the account you'd like to show tweets from:
`TWITTER_USERNAME = 'adafruit'`
### Change the Sleep Time
After fetching and displaying a tweet, the MagTag goes into a deep-sleep mode for 15 minutes. Modify the following line in the code to reflect how long the MagTag will enter the deep sleep mode for, in minutes.
`SLEEP_TIME = 15`
## Code Walkthrough
### Data Sources
This project fetches data directly from[Twitter's timeline API](https://developer.twitter.com/en/docs). A request is made to api.twitter.com to fetch the most recent status from a Twitter account, their full name, and their Twitter handle/username (such as @adafruit).
```python
# Set up where we'll be fetching data from
DATA_SOURCE = "https://api.twitter.com/1.1/statuses/user_timeline.json?count=1&screen_name=%s"%TWITTER_USERNAME
TWEET_TEXT = [0, 'text']
TWEET_FULL_NAME = [0, 'user', 'name']
TWEET_HANDLE = [0, 'user', 'screen_name']
```
### MagTag Library
The MagTag library makes it simple to create projects for the MagTag ePaper display. The code passes it the URL to fetch data from along with the JSON paths to retrieve the data.
- For more information about the MagTag library, [check out Melissa's guide here...](https://learn.adafruit.com/creating-magtag-projects-with-circuitpython/magtag-library-overview)
```python
magtag = MagTag(
url=DATA_SOURCE,
json_path=(TWEET_FULL_NAME, TWEET_HANDLE, TWEET_TEXT)
)
# Set Twitter OAuth2.0 Bearer Token
bearer_token = getenv("twitter_bearer_token")
magtag.set_headers({'Authorization': 'Bearer ' + bearer_token})
```
### Display Objects
The code sets up a bitmap image background (a white background with a black Twitter logo) and text fields to hold the contents of the API response.
```python
# Display setup
magtag.set_background("/images/background.bmp")
# Twitter username
magtag.add_text(
text_position=(70, 10),
text_font="/fonts/Arial-Bold-12.pcf",
)
# Twitter handle (@username)
magtag.add_text(
text_position=(70, 30),
text_font="/fonts/Arial-12.bdf",
text_transform=lambda x: "@%s"%x,
)
# Tweet text
magtag.add_text(
text_font="/fonts/Arial-Bold-12.pcf",
text_wrap=40,
text_maxlen=140,
text_position=(
10,
(magtag.graphics.display.height // 2)+20,
),
line_spacing=0.75,
)
# preload characters
magtag.preload_font()
```
### Text Transform
Unfortunately, Twitter's API returns a twitter username without the "@" prefix. To add the @ prefix before a twitter username, the code uses an anonymous function (a "lambda") which is passed to the `text_transform` parameter in the `magtag.add_text()` function.
So, by calling `text_transform``=lambda x: "@%s"%x`, we're creating a new anonymous function which looks like:
`def x_function(x):`
` return "@%s"%x`
### Update the Display
The main chunk of code attempts to fetch the URL from Twitter's API using `magtag.fetch()`. Then it parses out the data sources and displays the values on text labels.
```python
try:
value = magtag.fetch()
print("Response is", value)
except (ValueError, RuntimeError) as e:
print("Some error occured, retrying! -", e)
time.sleep(2)
print("Sleeping!")
magtag.exit_and_deep_sleep(SLEEP_TIME * 60)
```
The code exits and goes into deep sleep until the next `SLEEP_TIME` minutes.
`magtag.exit_and_deep_sleep(SLEEP_TIME * 60)`
