Message Jar is a messaging platform written in Python with Flask. This is a client for it made for the M5 Cardputer.

Message jar loads its configuration from mjconfig.json on the sd card. Here is an example configuration:
{
"ssid": "MyWifiNetwork",
"wifipassword": "wifi password",
"token": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
}To get a token, create an account at messagejar.pythonanywhere.com and click on your username. Then, if you navigate "Your api tokens", you should be able to create (and revoke) api tokens.
This code is heavily based off of the excellent MicroCOM project by geo-tp, and started off as a fork of it. Also used in this project is the SdService code from the Cardputer Game Station Emulators, which is also made by geo-tp.
