Can I use spi_master_nodma in data sampler applications?

[liubenyuan]

Hi, I want to build a data sampler using esp32, where analog signals are sampled using ADC. Esp32 read these samples from ADC using SPI interface and then transmit these data to PC via wifi.

I found your reply at
https://esp32.com/viewtopic.php?f=13&t=1383&p=6238&hilit=spi+adc#p6238

and I also post an issue at esp-idf
espressif/esp-idf#1148

The question is, can I use your SPI_MASTER_NODMA module in this issue? The ADC I am using is 16bit, 400ksps, and the ADC needs an ADC_CONV signal to initialize the conversion.

Thanks!
