以STM32F103单片机与STM32F103单片机之间进行SPI双机通信为例,直接使用DMA传输进行数据的发送与接收,最后通过实验证明了DMA传输的高效和准确性。
with the SPI dual-MIC communication between STM32F103 MCU and STM32F103 MCU taken as an example,data transmission and reception are carried out directly by using DMA transmission to prove the efficiency and accuracy of DMA transmission by experiments.
