This repo contains my ESP32 snippets. It’s set up as a
component. Please check the official ESP32 SDK documentation for details.
In your ESP32 project create a subdirectory components. GIT clone this
repository in there (either directly, or better as submodule).
Then the code should be available.
The amazining U8G2 library for monochrome OLEDs needs a HAL. I pilfered the HAL code from NKolban. His code is clearly marked and APACHE2 licensed.
To use the U8G2 just clone the repository into the components
directory.
