Cool that no one from espressif responded you.

I also have the same doubt.

Solved, the handle was null.

it was just initializing the capture timer last.

Hi, I can't call this function( mcpwm_soft_sync_activate(soft_sync_source); ) within the mcpwm capture callback ? I'm following this example: https://github.com/espressif/esp-idf/blob/v5.3.1/examples/peripherals/mcpwm/mcpwm_sync/main/mcpwm_sync_example_main.c static mcpwm_sync_handle_t soft_sync_sou...

@MicroController,

Do you think that mcpwm can work ?

Can i generate "one shot" like signals with mcpwm ?

The capture module already is working.

If the mcpwm signals is not generated by hardware, i think i will need to increase the isr priority of mcpwm above 3 too.

Thank's.

Not sure what your video shows. Are you seeing pulses of 5ms+ being generated where they should be ~100us? I think this shouldn't happen. Looks like something may be blocking interrupts for an abnormally long time, milliseconds instead of microseconds. - Or there's another bug in your pulse-generat...

Thank's.

I need that the rising edge interrupt and gptimer interrupt have the high highest isr priority within the system Interrupt priority is almost never the problem or solution in these cases. I'm thinking I'll have to use some hardware module to do this, maybe mcpwm or rmt or whatever. I need to contro...

As per the docs gptimer_set_alarm_action() is not allowed to be used in an ISR. How about initially (once) setting up the alarm to some high value, like 1000000, and then only adjust the count value appropriately? Like static const uint32_t ALARM_VALUE = 1000000; static void isr() { ... gp_timer_st...

@MicroController,

There is some order to set gptimer_set_alarm_action inside isr ?

I need do disable or stop the timer first ?

And then reenable or start the timer.

Thank's.

I tried here, but without success.
