Initialization and de-initialization functions:

Operation functions:

void StepMotor_WaveDriveChangeStep(int16_t number_of_step , uint16_t step_time); /* This function is for change step in wave drive mode */
void StepMotor_WaveDriveChangeAngle(float angle , uint16_t step_time);  /* This function is for change angle in wave drive mode */

How to use this library

The Stepper Motor library can be used as follows:

1. Add .h and source file in project.

2. Config GPIO as output in your project.

3. Config Stepper Motor in 'STEP_MOTOR_CONFIG.h' header, for example:

• Options:

  /* --- Config Port --- */
  #define _MOTOR_PORT     &PORTB
  #define _MOTOR_PIN_A    1
  
  /* --- Config Angle --- */
  #define _FULL_ANGLE     360.0f
  #define _STEP_QUANTITY  200.0f
  
  /* --- Config Driver --- */
  //#define _STM32_HAL_DRIVER  "STM32_GPIO/STM32_GPIO.h"
  

4. Using operation methods, for example:

Example 1:

int main(void)
{
	
    while (1) 
    {
  
      StepMotor_WaveDriveChangeStep(10, 250);
      _DELAY_MS(500);
    
      StepMotor_WaveDriveChangeStep(-12, 250);
      _DELAY_MS(500);
    
    }
}
   

Example 2:

int main(void)
{

    while (1) 
    {
    
      StepMotor_WaveDriveChangeStep(10, 250);
      _DELAY_MS(500);
      
      StepMotor_WaveDriveChangeStep(-12, 250);
      _DELAY_MS(500);
      
      StepMotor_WaveDriveChangeAngle(101.0, 250);
      _DELAY_MS(500);
      
      StepMotor_WaveDriveChangeAngle(-150.6, 250);
      _DELAY_MS(500);
    
    }
}
