以下是在STM32F030中使用TIM16输出反向PWM的代码示例:
```c
#include "stm32f0xx.h"
void TIM16_PWM_Init(void)
{
// 使能TIM16时钟
RCC->APB2ENR |= RCC_APB2ENR_TIM16EN;
// 配置TIM16为PWM模式1
TIM16->CCMR1 |= TIM_CCMR1_OC1M_2 | TIM_CCMR1_OC1M_1;
TIM16->CCMR1 &= ~TIM_CCMR1_OC1M_0;
// 配置TIM16的预分频器和自动重载寄存器,设置PWM频率为10kHz
TIM16->PSC = 48 - 1;
TIM16->ARR = 1000 - 1;
// 配置TIM16的CCR1寄存器,设置PWM占空比为50%
TIM16->CCR1 = 500 - 1;
// 配置TIM16的输出比较模式为PWM模式1
TIM16->CCER |= TIM_CCER_CC1E;
TIM16->BDTR |= TIM_BDTR_MOE;
// 配置TIM16的计数模式为向上计数
TIM16->CR1 &= ~TIM_CR1_DIR;
// 启动TIM16
TIM16->CR1 |= TIM_CR1_CEN;
}
int main(void)
{
// 初始化TIM16
TIM16_PWM_Init();
while (1)
{
// 程序主循环
}
}
```
