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。...

C51很好的IO模拟串口程序，也称软件UART。只需用一个定时器，实现中断接收。程序编写得很规范，有很多个晶振频率和串口频率可选。是一个比较好的软件串口程序。-C51 a good simulation of serial IO program, also known as the software UART. Just use a timer to achieve interrupt reception. Programming very standardized, there are many a crystal oscillator frequency and the frequency of an optional serial port. Is a relatively good software serial programs.
