Hall Current 13 Click is a compact add-on board that provides economical and precise AC or DC current sensing solutions. This board features the TMCS1107-Q1, a galvanically isolated Hall-effect current sensor capable of DC or AC current measurement with high accuracy, excellent linearity, and temperature stability from Texas Instruments. It enables the lowest drift, <3% full-scale error, and highest accuracy over time and temperature. It also provides a reliable 420V lifetime working voltage and 3kVRMS isolation between the current path and circuitry with uni/bidirectional current sensing. Besides, the user is allowed to process the output signal in analog or digital form.

We provide a library for the Hall Current 13 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 Hall Current 13 Click driver.
hallcurrent13_cfg_setup
Config Object Initialization function.
void hallcurrent13_cfg_setup ( hallcurrent13_cfg_t *cfg );
hallcurrent13_init
Initialization function.
err_t hallcurrent13_init ( hallcurrent13_t *ctx, hallcurrent13_cfg_t *cfg );
hallcurrent13_default_cfg
Click Default Configuration function.
err_t hallcurrent13_default_cfg ( hallcurrent13_t *ctx );
hallcurrent13_read_current
This function reads the input current level [A] based on HALLCURRENT13_NUM_CONVERSIONS of voltage measurements.
err_t hallcurrent13_read_current ( hallcurrent13_t *ctx, float *current );
hallcurrent13_read_voltage
This function reads raw ADC value and converts it to proportional voltage level.
err_t hallcurrent13_read_voltage ( hallcurrent13_t *ctx, float *voltage );
hallcurrent13_set_vref
This function sets the voltage reference for Hall Current 13 Click driver.
err_t hallcurrent13_set_vref ( hallcurrent13_t *ctx, float vref );
This example demonstrates the use of Hall Current 13 Click board by reading and displaying the input current measurements.
The demo application is composed of two sections :
Initializes the driver and logger.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
hallcurrent13_cfg_t hallcurrent13_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.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
hallcurrent13_cfg_setup( &hallcurrent13_cfg );
HALLCURRENT13_MAP_MIKROBUS( hallcurrent13_cfg, MIKROBUS_1 );
err_t init_flag = hallcurrent13_init( &hallcurrent13, &hallcurrent13_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}
Reads the input current measurements and displays the results on the USB UART approximately once per second.
void application_task ( void )
{
float current = 0;
if ( HALLCURRENT13_OK == hallcurrent13_read_current ( &hallcurrent13, ¤t ) )
{
log_printf( &logger, " Current : %.3f[A]\r\n\n", current );
Delay_ms ( 1000 );
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

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.
