H-Bridge 6 Click is a compact add-on board that contains a DC motor driver for automotive applications. This board features the VNHD7008AY, an H-bridge motor driver for automotive DC motor driving from STMicroelectronics. The VNHD7008AY, features an undervoltage shutdown, load current limitation, overload active power limitation, overtemperature shutdown, and more.
We provide a library for the HBridge6 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 HBridge6 Click driver.
hbridge6_cfg_setup
Config Object Initialization function.
void hbridge6_cfg_setup ( hbridge6_cfg_t *cfg );
hbridge6_init
Initialization function.
err_t hbridge6_init ( hbridge6_t *ctx, hbridge6_cfg_t *cfg );
hbridge6_default_cfg
Click Default Configuration function.
err_t hbridge6_default_cfg ( hbridge6_t *ctx );
hbridge6_reset
HW reset function.
void hbridge6_reset ( hbridge6_t *ctx );
hbridge6_enable_diagnostic
Enable the diagnostic function.
void hbridge6_enable_diagnostic ( hbridge6_t *ctx, uint8_t en_state );
hbridge6_set_direction
Adjust the direction function.
void hbridge6_set_direction ( hbridge6_t *ctx, uint8_t direction );
This is an example that demonstrates the use of H-Bridge 6 Click board.
The demo application is composed of two sections :
Initialization driver enables - I2C, reset the device and set default configuration, initialization and configure the PWM, also write log.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
hbridge6_cfg_t hbridge6_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.
