How we’re implemented SPI poling in ESP32- S2- WROOM module. But now I need to apply SPI DMA for Transmit and admit.
is ESP32- S2- WROOM module supports SPI DMA?
actually we searched in github, I find SPI DMA stack but in that no DMA related functions.
Given that you're using the ESP-IDF SPI driver and assign a DMA channel to the host driver when initializing it, you're already using DMA. The driver will use DMA for data transfers automatically.
