说明：  程序是关于新瑞达液晶模块显示的程序，程序不太难(procedures for the new LCD display Syncopate the procedure is not too difficult)

stm32f407 TIM1四路PWM,可调，环境MDK4，8M晶振，测试可用(stm32f407 tim1 PWM four-channel, adjustable)

八个发光二极管L1－L8分别接在单片机的P1.0－P1.7接口上，输出“0”时，发光二极管亮，开始时P1.0→P1.1→P1.2→P1.3→┅→P1.7→P1.6→┅→P1.0亮，重复循环。 (Eight light-emitting diodes L1-L8, respectively, then in the P1.0-P1.7 microcontroller interface, the output " 0" when the bright light-emitting diode, the beginning of P1.0 → P1.1 → P1.2 → P1. 3 → ┅ → P1.7 → P1.6 → ┅ → P1.0 Liang, repeat the cycle.)

spwm逆变器的电容电流和负载电压闭环控制 花了些时间调好的 给需要的人(spwm inverter capacitor current and load voltage closed-loop control took some time to those who need a good tune)

CH341 上位机软件，支持I2C UART等 接口(CH341 host computer software, support I2C, UART and other interfaces)

C51 编的音乐程序，关于如何编制音乐代码, 其实十分简单，频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍(C51 music program)
