Hello ! sorry for the off topic but it’s OK now, the config file as to be not too long for each line.
It seems that separate line is working :
dtoverlay=pitft28-capacitive,speed=32000000,fps=25
dtoverlay=pitft28-capacitive,touch-swapxy,touch-invx
But not when there is only one line config (too long)
I can now full test the engines, realy cool, I will post a video
