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...

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?

thanks for the reply. If I make the setting 13Mhz, I get the attached waveform: Any ideas?

Thanks

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...
