Software Support

We provide a library for the Hall Current 19 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 19 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of Hall Current 19 click board

by reading and displaying the current measurements.

The demo application is composed of two sections :

Application Init

After driver initialization and set the zero voltage reference.

void application_init ( void )
{
log_cfg_t log_cfg;
hallcurrent19_cfg_t hallcurrent19_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
hallcurrent19_cfg_setup( &hallcurrent19_cfg );
HALLCURRENT19_MAP_MIKROBUS( hallcurrent19_cfg, MIKROBUS_1 );
if ( ADC_ERROR == hallcurrent19_init( &hallcurrent19, &hallcurrent19_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, " Turn off the load current in the following 5 sec.\r\n" );
Delay_ms( 5000 );
if ( HALLCURRENT19_OK == hallcurrent19_set_zero_ref( &hallcurrent19 ) )
{
log_printf( &logger, " Process complete!\r\n");
}
else
{
log_error( &logger, " Zero reference." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

The demo application reads the current measurements [A] and displays the results.

Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
float voltage = 0;
if ( HALLCURRENT19_OK == hallcurrent19_get_current ( &hallcurrent19, &voltage ) )
{
log_printf( &logger, " Current : %.3f[A]\r\n\n", voltage );
Delay_ms( 1000 );
}
if ( HALLCURRENT19_OCD_ACTIVE == hallcurrent19_get_oc1( &hallcurrent19 ) )
{
log_printf( &logger, " Current over 7A \r\n" );
}
if ( HALLCURRENT19_OCD_ACTIVE == hallcurrent19_get_oc2( &hallcurrent19 ) )
{
log_printf( &logger, " Current over 17.5A \r\n" );
}
}
#define HALLCURRENT19_OCD_ACTIVE
Hall Current 19 Over Current Detection values.
Definition: hallcurrent19.h:78
uint8_t hallcurrent19_get_oc1(hallcurrent19_t *ctx)

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.HallCurrent19

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.
