Hall Current 14 click

Hall Current 14 Click is a compact add-on board that contains a precise solution for AC/DC current sensing. This board features the MCS1801, a fully integrated Hall-effect-based isolated linear current sensor designed for the current range of ±25A from Monolithic Power Systems (MPS). The galvanic isolation between the pins of the primary copper conductive path and the sensor leads allows the MCS1801 to replace optoisolators or other isolation devices. Applied current flowing through this copper conduction path generates a magnetic field that the differential Hall sensors convert into a proportional voltage, where after that, the user is given the option to process the output voltage as an analog or digital value.

Software Support

We provide a library for the Hall Current 14 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.

Library Description

This library contains API for Hall Current 14 Click driver.

Example Description

This example demonstrates the use of Hall Current 14 click board by reading and displaying the input current measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.

void application_init ( void )
{
log_cfg_t log_cfg;
hallcurrent14_cfg_t hallcurrent14_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
hallcurrent14_cfg_setup( &hallcurrent14_cfg );
HALLCURRENT14_MAP_MIKROBUS( hallcurrent14_cfg, MIKROBUS_1 );
err_t init_flag = hallcurrent14_init( &hallcurrent14, &hallcurrent14_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

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 ( HALLCURRENT14_OK == hallcurrent14_read_current ( &hallcurrent14, &current ) )
{
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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.HallCurrent14

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.
