Hi @RAc,
I am using and ESP32-S3, and it looks to have compatibility with DMA (Memory Types, in their ESP-IDF API). I am not familiar with DMA, what does it provide?
My images are fixed at size 1024 of type unsigned short. My image acquisition task currently runs at 6Hz but later we would like to have it down to 4Hz. My reply to Rahul provides more context on what type of processing happens on the image.
