The test software for the EarthSOM that is runnable on the STM32H745I-DISCO is available at this google drive link:
As of Feb 29th we have the ezLCD API working and most of the LUA scripting language. Note this is as is for testing purposes only and will not be supported after the EarthSOM ships with an LCD personality board.
We are looking for Makers, OEM's interested in using this in any application with or without an LCD. We are bringing up MicroPython on it next! Contact randy @ earth lcd com for more information. You can also hit the chat button on the bottom of the web page.
