使用51模拟I2C总线对CH450完成对6位LED数码管显示的操作。使用LED驱动芯片可分担51的工作量。-The use of 51 analog I2C bus on the CH450 completed six LED digital tube display operation. The use of LED Driver IC 51 may share the workload.

1．在发送端通过一个编码系统对待传数据预先编码，在接收端将传来的数据进行译码（复原）。对于双工信道（即可以双向传输信息的通道），每端都需要一个完整的编/译 码系统。 2．本程序的目的是大大提高通信的信道利用率，缩短信息传输时间，降低传输成本。 -1. In the transmitter through a coding system for pre-treatment data-coding the receiving end of data from the decoding (recovery). For dual-channel (two-way transmission of information can access), each side needs a complete encoding/decoding system. 2. The procedures are designed to greatly enhance the communication channel utilization, reduced transmission time, and lower transmission costs.
