Hall Current 5 click

Hall Current 5 Click is a very accurate electric current measurement Click boardâ„¢ based on the ACS733 IC. This IC is a galvanically isolated current sensor, which utilizes the Hall-effect principle.

Click library

Software Support

We provide a library for the HallCurrent5 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.

Library Description

This library contains API for HallCurrent5 Click driver.

Standard key functions :

Example key functions :

Examples Description

The demo application reads ADC value and current value.

The demo application is composed of two sections :

Application Init

Initialization device and ADC Init.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
HALLCURRENT5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
hallcurrent5_init( &hallcurrent5, &cfg );
// CLICK INIT
hallcurrent5_set_init_voltage( &hallcurrent5, 316 );
Delay_100ms();
}

Application Task

Reads current value in mA and this data logs to USBUART every 500ms.

void application_task ( void )
{
int16_t adc_value;
uint32_t sum_adc = 0;
uint8_t cnt;
float current;
// Task implementation.
tmp = hallcurrent5_generic_read( &hallcurrent5 );
log_printf( &logger, "** ADC value : [DEC]- %d, [HEX]- 0x%x \r\n", tmp, tmp );
Delay_ms( 1000 );
sum_adc = 0;
for(cnt = 0; cnt < 20; cnt++)
{
sum_adc += hallcurrent5_generic_read( &hallcurrent5 );
}
adc_value = ( sum_adc / 20 );
current = hallcurrent5_get_current( &hallcurrent5, adc_value/1.8 );
if ( current < 0 )
{
current = 0;
}
log_printf( &logger, " ADC value: %d \r\n", adc_value);
log_printf( &logger, " Current : \r\n", adc_value);
Delay_ms( 500 );
}

Note

Before the start of the program you have to set the starting voltage on AN pin. First, measure the voltage in mV on AN pin, when electronic load isn't > connected to the Click board, and pass that value as an input parameter of the voltage initialization function.

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.
