Library Description

The library covers all the necessary functions to control the H-Bridge Driver Click board™. User can use functions that control four separate input pins.

Key functions:

• void hbridgedriver_glo_enable ( uint8_t state ); - Function is used to turn the device on or off.
• void hbridgedriver_in_ls_2 ( uint8_t state ); - Function is used to set the state of the 'IL2' pin.
• void hbridgedriver_in_ls_1 ( uint8_t state ); - Function is used to set the state of the 'IL1' pin.

Examples description

The application is composed of three sections :

• System Initialization - Initializes GPIO and LOG structures, and sets AN, RST, CS, PWM and INT pins as output and start to write log.
• Application Initialization - Initalizes GPIO driver and turns the device on.
• Application Task - Demonstrates use of the H-Bridge Driver Click board™ by turning connected MOSFETs gates high or low in order to drive the motor forward, in reverse, brake or coast.

void application_task ( )
{
    mikrobus_logWrite( "The motor turns forward!", _LOG_LINE );
    hbridgedriver_forward( );
    Delay_ms( 1000 );
    mikrobus_logWrite( "The motor brakes!", _LOG_LINE );
    hbridgedriver_braking( );
    Delay_ms( 1000 );
    mikrobus_logWrite( "The motor turns in reverse", _LOG_LINE );
    hbridgedriver_reverse( );
    Delay_ms( 1000 );
    mikrobus_logWrite( "The motor coasting", _LOG_LINE );
    hbridgedriver_coasting( );
    Delay_ms( 1000 );
}

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.
