Yes, that is a structure for initializing the PCNT hardware. I have made more steps than you in Arduino, however I have not yet been able to make it work. I am normally very good at taking code snippets and getting a solution. For example, to initialize the struct with the declaration, you must prov...

Hi, I have a PWM set up on GPIO2 to perform a test. It would be great if I could stop the test after 2500 pulses. The previous version of the test bench used millis() and watched the time pass until 2500 * period millis had occurred and then the test stops. Now that I know PCNT exists, I want to uti...

The below code compiles for me in Arduino IDE (1.8.12 as of May 2020). I did use Sketch -> Include Library to add ESP32 library. In Windows 10, Arduino installs its libraries in the user folder documents. pcnt.h is in the folder: Documents\ArduinoData\packages\esp32\hardware\esp32\1.0.2\tools\sdk\in...
