UART DMA receive in circular mode
Posted: Wed Feb 12, 2020 8:57 am
Hello!
I have to receive data from uart very fast. It is possible to use uart with dma in circular mode using standard Chibios functions?
I think about DMA circular buffer with size about 1024bytes and callback or irq when each 256 bytes are received. It is possible to configure uart for this functionality using standard Chibios functions?
Thank you in advance for any help and advice,
best regards,
Franek
