H Bridge 12 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 DRV8823, a 4-bridge serial interface motor driver from Texas Instruments.
We provide a library for the H-Bridge 12 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 12 Click driver.
hbridge12_cfg_setup
Config Object Initialization function.
void hbridge12_cfg_setup ( hbridge12_cfg_t *cfg );
hbridge12_init
Initialization function.
err_t hbridge12_init ( hbridge12_t *ctx, hbridge12_cfg_t *cfg );
hbridge12_default_cfg
Click Default Configuration function.
err_t hbridge12_default_cfg ( hbridge12_t *ctx );
hbridge12_write_config
H-Bridge 12 write settings function.
err_t hbridge12_write_config ( hbridge12_t *ctx, hbridge12_config_t config_data );
hbridge12_set_current_scale
H-Bridge 12 set current scale function.
void hbridge12_set_current_scale ( hbridge12_t *ctx, uint8_t channel_sel, uint8_t out1_curr_scale, uint8_t out2_curr_scale );
hbridge12_turn_clockwise
H-Bridge 12 turn motor clockwise function.
err_t hbridge12_turn_clockwise ( hbridge12_t *ctx, uint8_t channel_sel );
This example demonstrates the use of the H-Bridge 12 Click board by driving the motor connected to OUT A and OUT B, 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. */
hbridge12_cfg_t hbridge12_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.

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.
