Hi,
There is possibility to trigger SPI-DMA with timer on ESP32C3,but using hardware settings?
I want to sample data from external adc using spi. I don't want to use method
where semaphore is released in timer ISR callback.I couldn't find it in the reference manual of ESP32C3.
Is this even possible to do on this chip?
Best regards,
Dawid

I don't think this is possible in hardware, sorry.
