单片机驱动数模转换器ADC0809的接口程序员(Single-chip driver DAC ADC0809 interface programmers)

一个电表行业专用的基于645规约的电表485通讯抄表程序，可以进行485总线抄表，645规约测试。程序技术要点就是规约数据传输协议的处理，如向电表发送数据时的控制码和数据长度、发送的数据部分(数据标识 + 密码 + 数据)、应答帧长度、结束标志等通讯协议的处理值得大家学习。(A meter-based industry-specific statute 645 meter 485 meter-reading procedure can be carried out 485 meter, 645 Statute of the test. Procedures for the technical elements of the statute is to deal with data transmission protocols, such as sending data to the meter when the control code and data length, send the data section (data logo+ Password+ Data), response frame length, marks the end of the treatment protocol, etc. everyone deserves to learn.)

通过单片机控制74hc138译码芯片的源程序，初学者还对hc138比较糊涂的可以下来看看，会有帮助的。(Through the MCU to control 74HC138 decoding chip of the source, for beginners to hc138 confused can down to have a look, will help.)
