电力系统电度表通讯协议，主要针对DL645协议标准(Power system meter communication protocol, mainly for DL645 protocol standards)

基于MAP430F149单片机的典型例题，很有帮助(Microcontroller based MAP430F149 a typical example, very helpful)

此代码是关于利用51单片机实现步进，滞留等程序的参考用。(This code is on the use of 51 single-chip stepper, detention and other procedures for reference.)

说明：  This is a generic FIFO buffer that can be used to store any kind of items. It is written in C language and can be compiled and used on almost any architecture. It was designed to be used on memory limited architectures such as microcontrollers. Examples of the applications that can be built with this library include:

① 设计进程控制块PCB表结构，分别适用于优先数调度算法和循环轮转调度算法。 ②建立进程就绪队列。对两种不同算法编制入队子程序。 ③编制两种进程调度算法：1）优先数调度；2）循环轮转调度 (① design process control block PCB table structure, respectively, for priority scheduling algorithm and round-robin scheduling algorithm. ② establish a process ready queue. Two different algorithms for the preparation of subroutine into the team. ③ preparing two kinds of process scheduling algorithm: 1) priority scheduling 2) round-robin scheduling)

说明：  51单片机控制GSM模块发短信和打电话的C源码(GSM single-chip control module 51 send text messages and phone calls the C source)

proteus仿真，以LPC2138芯片为核心生成PWM波，控制升压斩波电路（PWM），实现稳定的高电压输出。包含AD转换、串口通信。(proteus simulation. This design use PWM wave generated by LPC2138 to control boost circuit and realized a steady high voltage output. ADC and serial port communication are involved in the design.)
