Re: Generating DMX512 - simple demo

I'm not sure why ESP32 doesn't have OUT_PP, but OUT is the same thing. On STM32, OUT_PP is an alias for OUT anyway. (It's just to distinguish between push/pull and open-drain). The OUT_PP is not defined: What would be the best alternative ? >>> import machine >>> dir(machine) ['__class__', '__name_...

1.8.7 fails to install

i tried to flash the latest 1.8.7 firmware into the esp8266 nodemcu amica
however it will result in continuous text dump on the screen.
version 1.8.6 gives similar results

version 1.8.4 does work.
How to proceed?
