I am trying to use a RGB matrix (HUB75) with FastLED.
I installed the Smartmatrix library, but I can not compile the code.
DMAChannel.h error missing.
This file seems to be part of teensy core.
D:\Documents_D\Arduino\libraries\SmartMatrix\SmartMatrix.cpp:26:24: fatal error: DMAChannel.h: No such file or directory
Erreur de compilation pour la carte ESP32 Dev Module
I tried with Smartmatrix 3.x and 2.x but it's the same message.
I tried to comment the lines related to the DMA, but it's worse.
This RGB matrix works well with various ESP32 and adafruit_gfx, but I'd love to get there with FastLED.
I have not yet figured out in which file you can define the GPIO numbers connected to the HUB75, unless it is automatic?
But it's not the most important thing, it should first that the compilation works for my ESP32.
Thanks for your help.
