Can't be compiled on ESP32

[matthew798]

Since the ESP32's arduino libraries don't support some functions like analogWrite, compilation fails because some of the Atms use it. I was hoping there would be a workaround other than editing the library's source files manually as it will just be restored by PIO.

I'm have the same problem. I finded some posible solutions, but i not fully tested this libraries.

Not sure if this is relevant, but I'm able to build fine on my esp32 board using platformio with platform = espressif32
