Hi: Now I can make pwm freq to 2MHz,just let reduce .duty_resolution value. BUT, I want use :LEDC_HSCHn_CONF1_REG this register to let PWM out 138 preiod , and then, pwm gpio goto level 0, I use ledc_set_fade_with_step(LEDC_HS_MODE, LEDC_HS_CH0_CHANNEL, 0, 21, 138), the pwm out is not square wave, c...

Hi:
I use pwm and change duty_resolution = 8,freq_hz to 200*1000,duty to 20, but pwm freq just running 100*1000 Hz, Is this chip limit?

Hi: I had make a pwm high speed mode just output 100 cycle_cnt,in esp32_technical_reference_manual.pdf,picture 87. I want high timer ch0 use the 50% duty , and just have 100 hpoint,when the value of counter had reach hpoint , sig_out(?) will be high level, no pwm;for this , I set LEDC.channel_group[...
