inverter

PWM输入+DMA，亲测可用，有需要的朋友可以自行下载。(PWM input + DMA, pro-test available.)

说明：  ST7920带中文字库液晶原码程序 12864 keil的，串行方式 编写时已经考虑到往avr上的移植了，spi可以用avr硬件的，也可以用io模拟，甚至可以用mega48的串口做spi主机 ，经过我的测试串行方式，在cs无效时，7920还是可以接受数据，导致显示被误改，如果spi上接了其它器件，小心使用。(Driver with the original Chinese font LCD procedure code 12864 Keil. Serial way has been prepared to take into account the transplant avr, 20 avr hardware can be used, io can also use the simulation, or can even be done Serial mega48 20 mainframe, I have serial testing, cs in vain, 7920 can still receive data, resulting in the misuse of reform shows that if 20 on to other devices, careless use.)

输出PWM波，可移植性强。适用于stm32F103系列的单片机。例子也比较经典。(Output PWM wave, strong portability)

用于没有串口通信硬件的单片机，通过使用IO来模拟Uart的通信应用程序(For no hardware serial communication of single chip microcomputer, through the use of IO to simulate Uart communication applications)

无限警报器的代码设计 用于设计无线警报器(The code is designed for unlimited design alarm wireless alarm )

说明：  C51系列，用C语言编写，驱动1601液晶显示器(C51 series, with the C language, driving liquid crystal display 1601)

4463收发程序 SPI 可实现稳定收发 基于STM32F103C8T6(4463 TX RX code MCU IS STM32F103C8T6)

STM32控制AD9954产生正弦波等波形，频率幅值可调，包含两篇论文。(STM32 controls AD9954 to generate sinusoidal wave and other waveforms with adjustable frequency amplitude, including two papers.)

说明：  使用STM32驱动ADS1118，电压采样信息打印到串口上(STM32F103--->ADS1118)
