Hi, I search for a small example for SPI Master and DMA transfer. So that I can receive e.g. 15 bytes with DMA and get a transfer end to intrude/ message when it’s finished. Thanks in advance!

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.

I want to drive a chain of 86 RGB LEDs with SK6812 chip using a Renesas S7G2. The control should use as few CPU resources as possible, i.e. work via DMA if possible. Is there already a solution for such a control? External SDRAM is sufficiently available.
