This is caused by excessively fast clock frequency. It's really annoying to fix them one by one. Let's reduce these aggressive frequencies to 50 MHz. This is a safe and suggested value in the vendor SDK. Signed-off-by: Shiji Yang <yangshiji66@qq.com>...

Re: Custom SPI with maximum frequency 80MHz by Bryght-Richard » Fri Oct 04, 2024 9:15 pm Could you use the I2S peripheral in parallel mode? This would be able to apply CS, drive clock, and read 2-8 bits in parallel, but I'm not sure if ESP could send to ADC at the same...
