说明：  电力线载波模块资料，适用于电力线载波开发，(Power Line Carrier Module)

单片机M8电子负载，包括原理图，源程序；可以参考学习一下(MCU M8 electronic load, including schematics, source code can refer to learn about)

说明：  计算机编程手册（CPM）提供程序员理解如何编程给定计算机所需的信息。 本手册主要关注计算机本身，而不是计算机上运行的特定软件。(The Computer Programming Manual (CPM) provides information needed by a programmer to understand how to program a given computer. This manual focuses on the computer itself, not on particular software that will run on the computer.)

关于LPC932的RC522的S50非接触式IC卡程序源码程序，周立功模块配套程序更改，可正常使用(s50Mifare 1)

PSCAD三电平SVPWM,功能正常，可以用于仿真研究(PSCAD three-level SVPWM, normal function)

这是一个用keil-51编写的C51程序，里面含有温度控制的PID核心算法，这为温度的精密控制提供了保证，同时有液晶12864的驱动，而且有PCB电路图，供大家学习和参考。(This is a written with keil-51 C51 program, which contains the core PID temperature control algorithm, which is the precise temperature control can be ensured, while an LCD 12864 driver, but also PCB circuit, for your study and reference.)
