Software Support

We provide a library for the Current4 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 Current4 Click driver.

Example Description

This example showcases the ability of the Current 4 Click board.

It configures Host MCU for communication and reads the voltage of AN pin and calculates current on load output.

The demo application is composed of two sections :

Application Init

Initialization of the communication modules(ADC and UART).

void application_init ( void )
{
log_cfg_t log_cfg;
current4_cfg_t current4_cfg;
// Logger initialization.
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 115200;
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
current4_cfg_setup( &current4_cfg );
CURRENT4_MAP_MIKROBUS( current4_cfg, MIKROBUS_1 );
if ( ADC_ERROR == current4_init( &current4, &current4_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

In span on 500ms reads voltage and calculates the current on load.

void application_task ( void )
{
float current4_load_current = 0;
if ( ADC_ERROR != current4_read_load_current ( &current4, &current4_load_current ) )
{
log_printf( &logger, " > Load current : %.2f[A]\r\n", current4_load_current );
log_printf( &logger, "**********************\r\n" );
}
Delay_ms( 500 );
}

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.Current4

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.
