We have a hardware from M5Stack namely core 2 , fire and atom ([login to view URL]) based out of esp32 chips .This can run micro python , arduino sketch and C.
We have a code based on ANSI-C which is successfully compiled and running in X-86 Linux/Windows and ARM RaspberryPi and openwrt.
We need to port the same as mentioned here ( changing headers ) cross-compiling to esp32
The objective is to compile and debug the code also provide documentation on how it is done.
Details shall be provided through DMs
