When working with bare-metal programming on the Allwinner H3, UART communication with DMA can significantly improve efficiency. DMA allows data transfers between peripherals and memory without CPU intervention, reducing overhead. For example, configuring UART with DMA on the H3 involves setting up registers for baud rate, FIFO, and DMA channels. Proper initialization ensures smooth data flow, ideal for logging or real-time communication. Debugging can be done via serial monitors, ensuring accurate transmission.
