你可以使用以下代码实现STM32F103系列微控制器的步进电机梯形加减速控制:
```cpp
#include "stm32f10x.h"
#define STEPPER_PULSE_PIN GPIO_Pin_0
#define STEPPER_PULSE_PORT GPIOA
#define STEPPER_DIR_PIN GPIO_Pin_1
#define STEPPER_DIR_PORT GPIOA
void delay(uint32_t time) {
while(time--);
}
void stepper_init(void) {
GPIO_InitTypeDef GPIO_InitStructure;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
GPIO_InitStructure.GPIO_Pin = STEPPER_PULSE_PIN | STEPPER_DIR_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(STEPPER_PULSE_PORT, &GPIO_InitStructure);
}
void stepper_move(uint32_t steps, uint32_t speed) {
uint32_t accel_steps = steps / 2;
uint32_t decel_steps = steps - accel_steps;
uint32_t accel_delay = (1000000 / speed) / accel_steps;
uint32_t decel_delay = (1000000 / speed) / decel_steps;
uint32_t delay_time = accel_delay;
// 设置方向为正向
GPIO_SetBits(STEPPER_DIR_PORT, STEPPER_DIR_PIN);
// 加速阶段
for (int i = 0; i < accel_steps; i++) {
// 触发脉冲
GPIO_SetBits(STEPPER_PULSE_PORT, STEPPER_PULSE_PIN);
delay(delay_time);
GPIO_ResetBits(STEPPER_PULSE_PORT, STEPPER_PULSE_PIN);
// 延时
delay(delay_time);
// 更新延时时间
delay_time -= accel_delay / accel_steps;
}
// 匀速阶段
delay_time = (1000000 / speed) / accel_steps;
for (int i = 0; i < decel_steps; i++) {
// 触发脉冲
GPIO_SetBits(STEPPER_PULSE_PORT, STEPPER_PULSE_PIN);
delay(delay_time);
GPIO_ResetBits(STEPPER_PULSE_PORT, STEPPER_PULSE_PIN);
// 延时
delay(delay_time);
}
}
int main(void) {
stepper_init();
while(1) {
// 控制步进电机运动 200 步,速度为 1000 steps/s
stepper_move(200, 1000);
// 延时 1s
delay(1000000);
}
}
```
这段代码使用GPIOA的0号引脚作为步进电机的脉冲输出引脚,1号引脚作为方向控制引脚。你可以根据实际连接的引脚进行修改。在`main`函数中,可以通过调用`stepper_move`函数来控制步进电机的运动,其中`steps`参数表示步数,`speed`参数表示速度(单位:steps/s)。
