Library Description

The library covers all the necessary functions to control DC Motor 15 Click board™. DC Motor 15 Click communicates with the target board through the RST, CS, PWM and INT pins on mikroBUS™. This library offers functions for setting or clearing of RST, CS and PWM pins, and check the state of the INT pin, also user can use functions that drive motor forward and in reverse or apply brake functions.

Key functions:

• void dcmotor15_forward ( ); - Function is used to drive the motor forward.
• void dcmotor15_reverse ( ); - Function is used to drive the motor in reverse.
• void dcmotor15_brake ( ); - Function is used to brake the motor.

Examples description

The application is composed of three sections :

• System Initialization - Initializes LOG structure and sets RST, CS and PWM pins as output, and INT pin as input.
• Application Initialization - Initializes GPIO driver, powers up the device and starts log.
• Application Task - This example demonstrates the use of DC Motor 15 Click by driving the connected motor forward for 5 seconds, than braking for 2 second, and driving it in reverse for 5 more seconds, braking again for 2 second afterwards.

void application_task ( )
{
    mikrobus_logWrite( "The motor turns forward!", _LOG_LINE );
    dcmotor15_forward( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "The motor brakes!", _LOG_LINE );
    dcmotor15_brake( );
    Delay_ms( 2000 );
    mikrobus_logWrite( "The motor turns in reverse!", _LOG_LINE );
    dcmotor15_reverse( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "The motor brakes!", _LOG_LINE );
    dcmotor15_brake( );
    Delay_ms( 2000 );
}

Other mikroE Libraries used in the example:

• UART

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.
