It seems like there is no one use esp32 as a ADC sampler for wireless data collection.
Is there any demo on SPI dma using esp32?

How to use SPI of esp32 to read ADC samples periodically with fixed sample rate?
Hi, I want to use two ADC (ADS8864) and esp32 to sample analog waveform and send them to PC using WIFI. The data are sampled in a fixed sample rate, for example 100ksps for ADS8864, and I want to use SPI to read them into a buffer. When the data are ready, for example, 256 samples have been ...
