Library Description

The library covers all the necessary functions to control DC Motor 16 click board. There are functions for controlling motor speed, direction, starting and stoping.

Key functions:

• void dcmotor16_set_direction( uint8_t dir ) - Set motor direction
• void dcmotor16_ctrl_vref( uint16_t value ) - Control motor VRef (speed)
• void dcmotor16_stop( void ) - Motor stop

Examples description

The application is composed of three sections :

• System Initialization - Initialization SPI module and all necessary GPIO pins
• Application Initialization - Initialization driver init
• Application Task - Start motor example with change motor direction and speed

void application_task ( )
{
    uint16_t cnt;
    
    mikrobus_logWrite( ">> Motor start with direction [FORWARD] <<", _LOG_LINE );
    dcmotor16_set_direction( DCMOTOR16_DIR_FORWARD );
    for( cnt = 0; cnt <= 0x0100; cnt+= 25 )
    {
        dcmotor16_ctrl_vref( cnt );
        Delay_ms( 250 );
    }
    Delay_ms( 2000 );
    
    mikrobus_logWrite( ">> Motor stop ", _LOG_LINE );
    dcmotor16_stop();
    Delay_ms( 1000 );
    
    mikrobus_logWrite( ">> Motor start with direction [BACKWARD] <<", _LOG_LINE );
    dcmotor16_set_direction( DCMOTOR16_DIR_BACKWARD );
    for( cnt = 0; cnt <= 0x0100; cnt+= 25 )
    {
        dcmotor16_ctrl_vref( cnt );
        Delay_ms( 250 );
    }
    Delay_ms( 2000 );
    
    mikrobus_logWrite( ">> Motor stop ", _LOG_LINE );
    dcmotor16_stop();
    Delay_ms( 1000 );
}

• UART Library

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.
