利用51单片机及其接口电路模拟DMA的控制过程，由于数据的传输实际上不经过CPU而直接由A/D转换芯片传送到存储器，从而实现了数据的高速传送。-The use of 51 single-chip circuit simulation and its interface DMA control process, because the data transmission does not actually read the CPU and directly from the A/D conversion chip is sent to memory, thus realizing high-speed data transmission.
