H-Bridge 15 Click is a compact add-on board with an H-Bridge gate driver, also known as a full-bridge pre-driver. This board features the DRV8834, a dual-bridge stepper or DC motor driver from Texas Instruments.
We provide a library for the H-Bridge 15 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.
This library contains API for H-Bridge 15 Click driver.
hbridge15_cfg_setup
Config Object Initialization function.
void hbridge15_cfg_setup ( hbridge15_cfg_t *cfg );
hbridge15_init
Initialization function.
err_t hbridge15_init ( hbridge15_t *ctx, hbridge15_cfg_t *cfg );
hbridge15_default_cfg
Click Default Configuration function.
err_t hbridge15_default_cfg ( hbridge15_t *ctx );
hbridge15_set_pins
H-Bridge 15 set pins function.
err_t hbridge15_set_pins ( hbridge15_t *ctx, uint8_t set_mask, uint8_t clr_mask );
hbridge15_set_sleep
H-Bridge 15 set sleep function.
err_t hbridge15_set_sleep ( hbridge15_t *ctx, uint8_t sleep_state );
hbridge15_set_out_state
H-Bridge 15 set output function.
err_t hbridge15_set_out_state ( hbridge15_t *ctx, uint8_t out_state );
This example demonstrates the use of the H-Bridge 15 Click board by driving the motor in both directions with braking and freewheeling.
The demo application is composed of two sections :
Initializes the driver and performs the Click default configuration.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
hbridge15_cfg_t hbridge15_cfg; /**< Click config object. */
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
hbridge15_cfg_setup( &hbridge15_cfg );
HBRIDGE15_MAP_MIKROBUS( hbridge15_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == hbridge15_init( &hbridge15, &hbridge15_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( HBRIDGE15_ERROR == hbridge15_default_cfg ( &hbridge15 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
This example is driving a motor in both directions with motor braking and freewheeling in between.
void application_task ( void )
{
log_printf( &logger, " Motor in forward mode. \r\n" );
hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_FORWARD );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Motor brake is on \r\n" );
hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_BRAKE );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Motor in reverse mode. \r\n" );
hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_REVERSE );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
log_printf( &logger, " Motor is coasting \r\n" );
hbridge15_set_out_state( &hbridge15, HBRIDGE15_DRIVE_MOTOR_FREEWHEEL );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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. UART terminal is available in all MikroElektronika compilers.
