基于stm32单片机电压表设计,AD检测分压电阻电压值，根据电阻分压比算出所测电压，并显示在oled液晶上(Based on the design of voltage meter of STM32 single chip computer, AD detects the voltage value of dividing resistor, calculates the measured voltage according to the ratio of dividing resistor voltage, and displays it on OLED liquid crystal.)

这是FreeRTOS移植到STM32F0系列单片机的实例，已经验证成功，成功的驱动了LED,24L01,SPI,ADC等等外设。源码已经测试通过无误。(This is FreeRTOS transplanted to STM32F0 MCU instance, has been verified successfully, the success of driven LED, 24L01, SPI, ADC and so on peripherals. Source code has been tested correctly.)
