The Hall Current 4 Click is designed to measure relatively high current by using the integrated ACS70331 sensor.
We provide a library for the HallCurrent4 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 HallCurrent4 Click driver.
Config Object Initialization function.
void hallcurrent4_cfg_setup ( hallcurrent4_cfg_t *cfg );
Initialization function.
HALLCURRENT4_RETVAL hallcurrent4_init ( hallcurrent4_t ctx, hallcurrent4_cfg_t cfg );
Reads current in mA
float hallcurrent4_get_current_data ( hallcurrent4_t *ctx );
Reads raw (ADC) current data
uint16_t hallcurrent4_get_raw_data ( hallcurrent4_t *ctx );
Demo application shows is reading current data in mA using Hall current 4 Click.
The demo application is composed of two sections :
Configuring clicks and log objects.
void application_init ( void )
{
log_cfg_t log_cfg;
hallcurrent4_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.
hallcurrent4_cfg_setup( &cfg );
HALLCURRENT4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
hallcurrent4_init( &hallcurrent4, &cfg );
}Reads Current value in mA and logs this data to USBUART every 1 sec.
void application_task ( void )
{
float current;
current = hallcurrent4_get_current_data( &hallcurrent4 );
log_printf( &logger, " >> Current value: %.2f mA\r\n", current );
log_printf( &logger, " ------------------------- \r\n" );
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.
