简易数字电压表设计,日常生活可能需要用到，看看(Simple digital voltage meter, daily life may need to use)

STM32CubeMX _pwm示例,可以用于参考,希望对大家有帮助(STM32CubeMX _pwm Examples, which can be used for reference, I hope to help you all.)

说明：  本程序主要实现led点阵显示汉字的功能，并能使字体上下或者左右移动(This procedure led dot matrix display to achieve the main function of Chinese characters and fonts can move up and down or left and right)

建立环形缓冲区，将发送缓冲区建立成一个环形的缓冲区，在这个环形缓冲区内，通过头指针和尾指针来定位空白区和数据区(Ring buffer and send buffer created as a circular buffer in the ring buffer head and tail pointers to locate the blank area and data area)

RS232串口通信接收发送数字发送：从单片机P1、P2口输入按键信号， PC机RS232C口接收。 接收：PC机由RS232C口发送数字时，P4口连接的数码管显示。需要发送十六进制数，例如， 十进制数3，应该发送03(RS232 serial communication to send digital receiving )

说明：  利用温度控制制冷设备运行，实现空调扇自动制冷(Using temperature control refrigeration equipment to realize automatic refrigeration of air conditioning fan)
