ledc module doesn't work (esp32-idf4)
serg3295 opened this issue · comments
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
