好的,针对你的问题,我提供如下的程序代码,希望能够帮到你:
```c
#include "stm32f10x.h"
#define PWM_PERIOD 1000
#define PWM_STEPS 100
void TIM3_PWM_init(void)
{
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
TIM_OCInitTypeDef TIM_OCInitStructure;
RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);
TIM_TimeBaseStructure.TIM_Period = PWM_PERIOD - 1;
TIM_TimeBaseStructure.TIM_Prescaler = 71;
TIM_TimeBaseStructure.TIM_ClockDivision = 0;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseInit(TIM3, &TIM_TimeBaseStructure);
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = 0;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
TIM_OC3Init(TIM3, &TIM_OCInitStructure);
TIM_Cmd(TIM3, ENABLE);
}
void Motor_init(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8 | GPIO_Pin_9;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(GPIOA, &GPIO_InitStructure);
}
void Motor_control(int duty_cycle)
{
if(duty_cycle > PWM_STEPS) duty_cycle = PWM_STEPS;
if(duty_cycle < -PWM_STEPS) duty_cycle = -PWM_STEPS;
if(duty_cycle >= 0)
{
GPIO_SetBits(GPIOA, GPIO_Pin_8);
GPIO_ResetBits(GPIOA, GPIO_Pin_9);
TIM_SetCompare3(TIM3, (PWM_PERIOD - 1) * duty_cycle / PWM_STEPS);
}
else
{
GPIO_SetBits(GPIOA, GPIO_Pin_9);
GPIO_ResetBits(GPIOA, GPIO_Pin_8);
TIM_SetCompare3(TIM3, (PWM_PERIOD - 1) * (-duty_cycle) / PWM_STEPS);
}
}
int main(void)
{
Motor_init();
TIM3_PWM_init();
while(1)
{
if(GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_10) == RESET)
{
Motor_control(PWM_STEPS);
}
else
{
Motor_control(-PWM_STEPS);
}
}
}
```
这个程序是用来控制JGB37-520霍尔编码器直流电机的,其中包括了初始化PWM信号以及电机的初始化和控制。在使用时,你需要将它下载到你的STM32C8T6开发板中,并将霍尔编码器直流电机连接到相应的引脚上,即可控制电机的转动。
