Library Description

The library covers all the necessary functions that enables the usage of the H-Bridge 5 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 foreward and reverse motion, apply diferent kinds of brake functions and synchronization fast decay functions, enable and disable device, or to put it to sleep. For better control over the device generic read and write functions are made available to the user as well as "set port" and ADC functions.

Key functions:

• void hbridge5_foreward() - Function is used to put motor into foreward motion.
• void hbridge5_reverse() - Function is used to put motor into reverse motion.
• void hbridge5_brake_low() - Function is used to brake motor to a halt.

Examples description

The application is composed of three sections :

• System Initialization - Initializes I2C module, LOG and GPIO structures, sets RST pin as output and INT and AN pins as input.
• Application Initialization - Initalizes I2C driver, configures all ports as output and writes an initial log.
• Application Task - (code snippet) This example demonstrates the use of H-Bridge 5 Click board, by running dc motor foreward, then stoping and then running it in reverse and stoping again.

void application_task ( )
{
    hbridge5_foreward( );
    Delay_ms( 3000 );
    
    hbridge5_brake_low( );
    Delay_ms( 1000 );
    
    hbridge5_reverse( );
    Delay_ms( 3000 );
    
    hbridge5_brake_low( );
    Delay_ms( 1000 );
}

Other mikroE Libraries used in the example:

• I2C
• UART
• ADC
• Conversions

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.
