奋斗版stm32开发板PWM实验，是学习stm32实现PWM调速的好实验-Struggle version stm32 development board PWM experiment PWM speed learning stm32 experimental

基于STM32的32位为控制器的生成PWM波形的详细的C程序代码工程文件。本代码实现如下功能：利用TIM3的通道2（PA7）产生PWM来控制DS0的亮度，实现DS0从 暗->亮->暗的循环变化。-Detailed engineering documents C code based STM32 32-bit controller for PWM waveform generation. This code implements the following functions: use
