Hello, I got my M5Tough and works GREAT out of the box with default loaded app (tough tools)
what ever other application I try to use from GITHUB loaded via Arduino or Visual Studio Code comes out with almost no brightness at all...
now some of the app I was tested were for CORE2... but stilldownload M5Tough app from GITHUB and result are the same!!!!
Did try two approach on raising brightness SetBrighness and the voltage thing (forgot it sry!) and nothing nada!
