Hello,
I have searched and found how to setup the 8-bit and 16-bit timers on Atmega328 and Atmega2560 to blink a LED, for example, but I could not find how to do that on nodeMCU esp8266 and esp32 using the Arduino IDE.
Can you show me some code on how to do that? (set timer/interrupt to blink a LED each half-second on nodeMCU esp8266 and esp32)

Thanks,
Etienne

Hi.
At the moment we don’t have any tutorials about that.
But, I found this example code for the ESP32:

In the following link you can find examples for both boards:

I hope this helps.
