Hi,
I'm playing with Pulse counter and timers to be able develop frequency counter. Unfortunatelly, calling "pcnt_counter_clear" function doesn't clear the pulse counter value...
I know, that in the https://github.com/espressif/esp-idf/issues/638 was reported by Igor, that it was fixed, but I'm not ...

Thanks. It helped.

extern "C" {
#include "soc/pcnt_struct.h"
}
#include "driver/pcnt.h"

solved the issue and Pulse counter is working now.

/* interrupt function for PCNT */
void IRAM_ATTR pcnt_example_intr_handler(void* arg) {
uint32_t intr_status;
intr_status = PCNT.int_st.val;

Folks,
I'm playing with Pulse Counter in ESP32.
I'm able count pulses now, but can't invoke ISR. Resp. - I'm able to define ISR, but program probably get-lock in the ISR and never release it.
I'm trying to find the root-cause. Maybe, the flag for finishing interrupt is not cleared.
So, I would like ...

Joster, Superkurt: Any solution with PCNT and pulse Counting of esp32.

Thanks,

Friends,
I would like to use pulse counting on ESP32 in Arduino IDE. Unfortunately, IDF offers a lot of functions for working with counter, I don't know, how to use it in Arduino IDE. Honestly, I'm using Platform IO, but nevermind...

Arduino IDE doesn't know "pcnt" functions, like
pcnt_unit_config ...
