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.)

说明：  用C语言编写STM32嵌入式程序，设计一个万年历系统，并用HX1230屏显示相关的时间信息。 基本要求： 1.C语言程序要求是模块化设计。 2.该万年历要求能显示时间（时、分、秒）、年月日及闹钟定时时间（分、秒）。 3.该系统由2-3个按键可调整显示的时间、年月日及闹钟定时时间，具体各个按键功能及编程方式自定。 4.该闹钟可以定时时间到，LED将发出提示闪光，且持续30s。 5.HX1230屏能驱动显示。 6.定时时间可被打断，即打断后恢复时继续计时。 7.设置闹钟报警功能； 8.利用STM32自带的温度传感器功能，使系统能显示当前环境温度值。(STM32 embedded program is written in C language, a calendar system is designed, and relevant time information is displayed on HX1230 screen. Basic requirements: 1. The requirement of C language program is modular design. The calendar requires that time (hours, minutes, seconds), year, month, day and alarm clock timing time (minutes, seconds) be displayed. 3. The system can adjust the display time, year, month, day and alarm clock timing time by 2-3 keys, and the function and programming mode of each key are self-determined. 4. The alarm clock can be scheduled to arrive, and the LED will give a prompt to flash, and lasts for 30 seconds. 5. HX1230 screen can drive display. 6. Timing time can be interrupted, i.e. when the interruption is resumed, the timing will continue. 7. Setting alarm function of alarm clock; 8. Using the temperature sensor function of STM32, the system can display the current environmental temperature)
