I want to receive a rather odd serial data stream with the ESP32 DMA. The signal for a YAC512 DAC [a 90s "floating point DAC" taking the input from an YMF262/OPL3 soundchip]. Basically a frame consists of 36bit -> 2x 16bit + 2bit padding each. Data used by the DAC is 3bit padding (not used by YAC512...

Ah OK, thanks for the hint! To fill in others that have the same problem: Using nothing but pin up/down in the main loop results in a short burst at about 1MHz on my scope. Literally just setup: pinMode(5, OUTPUT); loop: GPIO_REG_WRITE(GPIO_OUT_W1TS_REG, 0b00000000000000000000000000100000); GPIO_REG...

Hi guys! How does one generate a stable clock signal above what the LED PWM provides? I need a 2MHz square wave signal with 50:50 duty cycle. Of cause the ESP32 is fast and I could use a RTOS thread, but there must be a more elegant way. I see CLKout1, CLKout2, CLKout3 - #1 + #2 are on the USB pins ...
