Library Description
The library covers all the necessary functions that enables the usage of the Stepper 14 Click board. It initializes and defines the I2C driver and drivers that allow full control of the device to the user. User can use the device to control forward and reverse motion, apply brake and coast functions for brushless dc motors, and forward and reverse motion in full step and half step for stepper motors.
Key functions:
void stepper14_step_motor ( uint8_t interface, uint8_t direction, uint32_t steps_no ); - Function is used to drive two or four wire stepper motor in user defined direction, one step at a time.void stepper14_set_half_step ( uint8_t hl_step ); - Function is used to set specific half step.void stepper14_control_mode_set ( uint8_t mode ); - Function is used to set mode of operation.Examples description
The application is composed of three sections :
void application_task ( )
{
mikrobus_logWrite( " Stepper motor makes one turn forward ", _LOG_LINE );
stepper14_step_motor( STEPPER14_4_PIN_INTERFACE, STEPPER14_DIR_CW, 200 );
Delay_ms( 1000 );
mikrobus_logWrite( " Stepper motor makes one turn backward ", _LOG_LINE );
stepper14_step_motor( STEPPER14_4_PIN_INTERFACE, STEPPER14_DIR_CCW, 200 );
Delay_ms( 1000 );
}

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
