Something so simple shouldn't be this difficult. :(
I have not examined your code, but generally the biggest porting issue from Arduino (UNO, Mega, Nano, Micro) and ESP32 is that AVR 8-bit uC has int defined as 16-bits and int on ESP32 is 32-bit.

Good luck.

Re: ESP32 Task

I have a forum post that hopefully explains the dualcore programming a bit:

A powered USB hub will sacrifice itself and protect the PC.

Re: Question regarding core usage on the esp32 with Arduino esp-now example

You may want to look at my Arduino multi-tab example here... a rework of the Andreas Spiess' code on YouTube.

Re: ESP32 Github Core-- Is this a joke

... I understood that the whole basis of the Arduino environment was to provide a low tech high level entry into the AVR world. This seems to be negated by the new Espressif designers, ... Once upon a time, "low tech entry..." and "AVR" were appropriate for Arduino. Then because the Arduino GUI tea...

Re: esp32 seems dead

It is critically important that one observes the current limitations of the output pins and always utilize a current limiting resistor. The ESP32 sink/source current is referenced to +3.3V and not to +5V, so if you are sinking current (output port goes low) and the LED is at +5 Volts, this is not a ...

Re: Newbie question: Lolin32 don't want to user Micropython

The first time you successfully upload an Arduino sketch, the micropython will be overwritten,
