This is a repository for my projects with the M5Stack, a ESP32 based stackable prototyping device.
|
## M5 interface for ARNweb API
|
||||||
You can browse different projects by browsing through the branches.
|
|
||||||
|
|
||||||
More info will be hosted on ARNweb later.
|
If you want to use this for some reason you need to run [ARNweb API](https://gitea.arnweb.nl/arne/arnweb-api) on a server over HTTPS. Then put the url to the ```/system``` subsection on line 98 and your CA certificate in the ```const char* ca``` on line 34.
