stm32c8t6库函数编写pwm控制两轮电机

你可以使用STM32的库函数来编写PWM控制两轮电机的代码。下面是一个简单的示例代码，假设使用的是TIM3定时器和GPIO引脚：

首先，需要初始化定时器和GPIO引脚的配置：

#include "stm32f10x.h"

void TIM3_Configuration(void) {
  TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
  TIM_OCInitTypeDef TIM_OCInitStructure;
  GPIO_InitTypeDef GPIO_InitStructure;

  // 使能定时器时钟
  RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);
  // 使能GPIO引脚时钟
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

  // 配置GPIO引脚
  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6 | GPIO_Pin_7;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
  GPIO_Init(GPIOA, &GPIO_InitStructure);

  // 配置定时器
  TIM_TimeBaseStructure.TIM_Prescaler = 71; // 定时器分频，72MHz / (71+1) = 1MHz
  TIM_TimeBaseStructure.TIM_Period = 999;   // 定时器计数上限，1MHz / (999+1) = 1kHz
  TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
  TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);

  // 配置PWM模式
  TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
  TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
  TIM_OCInitStructure.TIM_Pulse = 0; // 初始占空比为0%
  TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
  TIM_OC1Init(TIM3, &TIM_OCInitStructure);
  TIM_OC2Init(TIM3, &TIM_OCInitStructure);

  // 使能定时器
  TIM_Cmd(TIM3, ENABLE);＊＊＊
