Library Description

The library covers all the necessary functions to control DC Motor 14 click board. DC Motor 14 click communicates with the target board through the AN and RST lines on MikroBUS. This library offers functions for setting or clearing of both pins used for communication, also user can use functions that drive motor forward and in reverse or apply brake and stop functions.

Key functions:

• void dcmotor14_forward ( ); - Function is used to drive the motor forward.
• void dcmotor14_reverse ( ); - Function is used to drive the motor reverse.
• void dcmotor14_brake ( ); - Function is used to brake the motor.

Examples description

The application is composed of three sections :

• System Initialization - Initializes LOG structure and sets AN and RST pins as output.
• Application Initialization - Initializes GPIO driver and starts log.
• Application Task - This example demonstrates the use of DC Motor 14 click by driving it forward motion for 5 seconds, than applying brakes it for 2 second, and then driving it in reverse for 5 seconds, after that, it stops for 2 second.

void application_task ( )
{
    mikrobus_logWrite( "The motor turns forward!", _LOG_LINE );
    dcmotor14_forward( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "The motor brakes!", _LOG_LINE );
    dcmotor14_brake( );
    Delay_ms( 2000 );
    mikrobus_logWrite( "The motor turns in reverse", _LOG_LINE );
    dcmotor14_reverse( );
    Delay_ms( 5000 );
    mikrobus_logWrite( "The motor stops", _LOG_LINE );
    dcmotor14_stop( );
    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.
