ledc module doesn't work (esp32-idf4) #3558

Closed serg3295 closed 1 year ago

serg3295 commented 1 year ago

Actual behavior

When I try to create a channel object using the ledc.newChannel method ESP throws an error

assert failed: ledc_clk_cfg_to_global_clk ledc.c:446 (false)

and then ESP restarts.

When I applied the pull request setting results in automatic clock selection ledc module began to work correctly.

Could you merge this pull request into the esp32-idf4 branch?

Test code

myChannel = ledc.newChannel({
  gpio=5,
  bits=ledc.TIMER_13_BIT,
  mode=ledc.HIGH_SPEED,
  timer=ledc.TIMER_0,
  channel=ledc.CHANNEL_0,
  frequency=1,
  duty=4096
})

Apologies for the huge delay. The fix has now been merged.
