Hello, everyone, I am using an optical encoder with 600 pulses per revolution. For this I am programming it with PCNT (Espressif), which works well. At this point I would like to reduce the pulse count to 300, 200, 100 pulses per revolution by adjusting some parameter of PCNT. Unfortunately I do…

Hi gfvalvo, I implemented the code you kindly sent me and all is working perfectly. Thanks again. Roberto

You've made at least 28 other posts on this site. By now you should have an understanding of what's wanted in order to help us help you, right? Like code in code tags, right? So, please, start off doing this the right way. So, we don't have to play 2000 questions. Anyways, the code you posted is no…

Hi Stefan, I have an ESP32-Wroom microcontroller. Thank you, Roberto

Dear idahowalker, I apologise for my haste to get a useful answer and for my weak knowledge of English, which prevents me from fully understanding what is written in Espressif. It is not easy working with translators.... However, I will apply your suggestion. Thank you, Roberto

Hi Stefan, my microcontroller is an ESP32-WROOM Dev Kit chip, an 38 pin dual in line package. Sorry.... :face_with_head_bandage:

Hello, I have carefully read what the Espressif website reports regarding the Puse Counter (PCNT), as had been recommended to me. I have set up my site with the following code: //--- Counter setup for Rotary Encoder --------------------- pcnt_config_t pcnt_config_A;// structure for A p…

Basically you need to set up a counter incremented by each pulse which overflows after 2, 3 or pulses. That will divide your steps per rev by 2 or 3 or 4, or whatever number you want.
