CC2530 步进电机控制停车场抬杆代码详解

停车场抬杆的步进电机控制可以使用 CC2530 微控制器。以下是基于 CC2530 的步进电机控制停车场抬杆代码。

代码分为两个部分，一个是 CC2530 微控制器的初始化和配置，另一个是步进电机控制的代码。

初始化和配置代码：

#include <stdint.h>
#include "ioCC2530.h"
#include "hal_mcu.h"
#include "hal_board.h"
#include "hal_led.h"
#include "hal_uart.h"
#include "hal_lcd.h"
#include "hal_key.h"
#include "hal_i2c.h"
#include "hal_timer_32k.h"
#include "hal_timer_1.h"
#include "hal_timer_2.h"
#include "hal_assert.h"
#include "hal_types.h"

void MCU_Init(void)
{
  /* Set system clock */
  CLKCONCMD = (CLKCONCMD & ~0x07) | CLKCONCMD_32MHZ;
  while (CLKCONSTA != CLKCONCMD_32MHZ);

  /* Set timer 1 as 16-bit timer */
  T1CTL &= ~0x02;

  /* Set timer 1 to use system clock as source */
  T1CTL &= ~0x0C;

  /* Enable timer 1 interrupt */
  T1IE = 1;

  /* Enable global interrupts */
  EA = 1;
}

步进电机控制代码：

#include "step_motor.h"

#define STEP_MOTOR_DIR  P1_0
#define STEP_MOTOR_EN   P1_1
#define STEP_MOTOR_STEP P1_2

void StepMotorInit(void)
{
  /* Set the direction pin as output */
  P1DIR |= BIT0;

  /* Set the enable pin as output */
  P1DIR |= BIT1;

  /* Set the step pin as output */
  P1DIR |= BIT2;

  /* Disable the motor */
  STEP_MOTOR_EN = 1;

  /* Set the direction to forward */
  STEP_MOTOR_DIR = 1;
}

void StepMotorStep(uint16_t steps)
{
  uint16_t i;

  /* Enable the motor */
  STEP_MOTOR_EN = 0;

  for (i = 0; i < steps; i++)
  {
    /* Toggle the step pin */
    STEP_MOTOR_STEP ^= 1;

    /* Wait for some time */
    delay_us(1000);
  }

  /* Disable the motor */
  STEP_MOTOR_EN = 1;
}

void StepMotorRotate(int16_t angle)
{
  uint16_t steps;

  /* Calculate the number of steps required to rotate the motor by the given angle */
  steps = (uint16_t)(((float)angle / 360.0) * 200.0);

  /* Rotate the motor */
  StepMotorStep(steps);
}

在主函数中调用 StepMotorInit() 初始化步进电机控制，然后调用 StepMotorRotate(angle) 旋转步进电机。

注意：这只是一个示例代码，实际应用中可能需要根据具体情况进行修改。
