stm32c8t6驱动IRF540N驱动代码

以下是一个简单的基于STM32C8T6驱动IRF540N的示例代码：

#include "stm32f1xx.h"

#define IRF540N_PIN GPIO_PIN_0
#define IRF540N_PORT GPIOA

void PWM_Init(void)
{
    TIM_HandleTypeDef htim;

    TIM_OC_InitTypeDef sConfigOC;
    TIM_MasterConfigTypeDef sMasterConfig;

    htim.Instance = TIM2;
    htim.Init.Prescaler = 0;
    htim.Init.CounterMode = TIM_COUNTERMODE_UP;
    htim.Init.Period = 255;
    htim.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
    HAL_TIM_PWM_Init(&htim);

    sConfigOC.OCMode = TIM_OCMODE_PWM1;
    sConfigOC.Pulse = 0;
    sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH;
    sConfigOC.OCNPolarity = TIM_OCNPOLARITY_HIGH;
    sConfigOC.OCFastMode = TIM_OCFAST_DISABLE;
    sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET;
    sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET;
    HAL_TIM_PWM_ConfigChannel(&htim, &sConfigOC, TIM_CHANNEL_1);

    sMasterConfig.MasterOutputTrigger = TIM_TRGO_RESET;
    sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
    HAL_TIMEx_MasterConfigSynchronization(&htim, &sMasterConfig);

    HAL_TIM_PWM_Start(&htim, TIM_CHANNEL_1);
}

void IRF540N_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStruct;

    __HAL_RCC_GPIOA_CLK_ENABLE();

    GPIO_InitStruct.Pin = IRF540N_PIN;
    GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;
    HAL_GPIO_Init(IRF540N_PORT, &GPIO_InitStruct);
}

void IRF540N_SetDuty(uint8_t duty)
{
    TIM_OC_InitTypeDef sConfigOC;

    sConfigOC.OCMode = TIM_OCMODE_PWM1;
    sConfigOC.Pulse = duty;
    sConfigOC.OCPolarity = TIM_OCPOLARITY_HIGH;
    sConfigOC.OCNPolarity = TIM_OCNPOLARITY_HIGH;
    sConfigOC.OCFastMode = TIM_OCFAST_DISABLE;
    sConfigOC.OCIdleState = TIM_OCIDLESTATE_RESET;
    sConfigOC.OCNIdleState = TIM_OCNIDLESTATE_RESET;
    HAL_TIM_PWM_ConfigChannel(&htim, &sConfigOC, TIM_CHANNEL_1);

    if(duty > 0)
    {
        HAL_GPIO_WritePin(IRF540N_PORT, IRF540N_PIN, GPIO_PIN_SET);
    }
    else
    {
        HAL_GPIO_WritePin(IRF540N_PORT, IRF540N_PIN, GPIO_PIN_RESET);
    }
}

int main(void)
{
    PWM_Init();
    IRF540N_Init();

    while(1)
    {
        for(int i=0; i<256; i++)
        {
            IRF540N_SetDuty(i);
            HAL_Delay(10);
        }

        HAL_Delay(1000);

        for(int i=255; i>=0; i--)
        {
            IRF540N_SetDuty(i);
            HAL_Delay(10);
        }

        HAL_Delay(1000);
    }
}

这个代码使用了STM32 HAL库来驱动IRF540N。使用TIM2的PWM输出来控制电机转速。通过改变PWM的占空比来改变电机的转速。同时，使用GPIO口来控制IRF540N的Gate引脚，以控制其导通与否，从而控制电机的启停。注意在使用之前需要导入STM32 HAL库，具体请参考STM32官方教程。
