Abstract: The paper proposed to use DMA function built-in MCU to implement caching and transmission of underground high speed data acquisition system of coal mine. The data moves through the DMA quickly, which saves MCU resources, and makes MCU can perform other operations, so as to achieve high speed data acquisition of coal mine.
