Can I 'mirror' a GPIO signal on another GPIO?
Please help! I'm trying to debug a new custom ESP32-WROOM-32D based board. I have access to a couple of test pins that are connected to some of the ESP32 GPIO's on the board(GPOI's 2,4 & 5), but I want to measure clock signals on the i2s pins (BCLK = GPIO 26, WCLK = GPOI 25 and DOUT = GPO 23). As it...

Re: Creating >10MHz clock using PWM and LEDC
I'm actually using Arduino rather than IDF at the moment. It's got me thinking if perhaps that could be part of the problem?

Re: Creating >10MHz clock using PWM and LEDC
thanks for the reply. If I make the setting 13Mhz, I get the attached waveform:

Creating >10MHz clock using PWM and LEDC
Hi, I'm hoping someone can help as this is driving me mad! I'm trying to generate a square wave clock signal from the ESP32 GPIO0 with a frequency of 13MHz and a 50% duty cycle. From what I've read elsewhere, it seems that a clock up to 40MHz should be possible using LEDC with a timer duty resolutio...
