rusEFI can communicate with external universe via native USB or some sort of TTL mode We have an interesting situation with TTL communication channels, we have 1) SERIAL - this one was implemented first simply because the code was readily available (works on stm32) this one is most suitable for streaming HAL API this one is not great since each byte requires an IRQ and with enough IRQ delay we have a risk of data loss 2) UART DMA - the best one since FIFO buffer reduces data loss (works on stm32) We have two halves of DMA buffer - one is used for TTL while rusEFI prepares next batch of data in the other side. We need idle support in order to not wait for the complete buffer to get full in order to recieve a message. Back when we were implementing this STM32_DMA_CR_HTIE was not available in ChibiOS driver so we have added it. we have custom rusEFI changes to ChibiOS HAL driver v1 F7 uses driver v2 which currently does not have rusEFI changes. open question if fresh ChibiOS is better in this regard. 3) UART this one is useful on platforms with hardware FIFO buffer like Kinetis. stm32 does not have such buffer so for stm32 UART without DMA has no advantages
