ESP32 compilation error

[Louis]

[SOLVED] 64x32 LED matrix Library recommendation ?!

@Louis, see SmartMatrix/SmartMatrixAPA102RefreshEsp32_Impl.h at teensylc · pixelmatix/SmartMatrix · GitHub this seems wrong in an Esp32_Impl file. @GeorgeFlorian you are however getting this error in SmartMatrix_Impl.h which shows that you are likely using the master branch which does not support ESP32, instead of the teensylc branch which does support ESP32.
