Hall current 2 Click is a very accurate current measurement Click board™, which relies on the Hall effect.
We provide a library for the HallCurrent2 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for HallCurrent2 Click driver.
Config Object Initialization function.
void hallcurrent2_cfg_setup ( hallcurrent2_cfg_t *cfg );
Initialization function.
HALLCURRENT2_RETVAL hallcurrent2_init ( hallcurrent2_t ctx, hallcurrent2_cfg_t cfg );
Click Default Configuration function.
void hallcurrent2_default_cfg ( hallcurrent2_t *ctx );
This function reads data from the desired register.
void hallcurrent2_generic_read ( hallcurrent2_t *ctx );
This function changes reset chip states to reset the chip.
void hallcurrent2_reset( hallcurrent2_t *ctx );
Reads current's value in mV.
int16_t hallcurrent2_get_current( hallcurrent2_t *ctx );
This application very accurately measures current using Hall effect.
The demo application is composed of two sections :
Initializes Driver init and reset chip
void application_init ( void )
{
log_cfg_t log_cfg;
hallcurrent2_cfg_t cfg;
/**
* 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.
hallcurrent2_cfg_setup( &cfg );
HALLCURRENT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
hallcurrent2_init( &hallcurrent2, &cfg );
hallcurrent2_reset( &hallcurrent2 );
}
Reads current and logs on usbuart every 1 second.
void application_task ( void )
{
int16_t current_data;
current_data = hallcurrent2_get_current( &hallcurrent2 );
log_printf( &logger, "--- Current : %d mA\r\n", current_data );
Delay_ms ( 1000 );
}The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
