Click library

  • Author : Stefan Filipovic
  • Date : Jun 2024.
  • Type : I2C type

Software Support

We provide a library for the 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 Current 14 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of Current 11 click board by reading and displaying the input current measurements.

The demo application is composed of two sections :

Application Init

Initializes the driver and calibrates the zero current offset and data resolution at 3A load current.

void application_init ( void )
{
log_cfg_t log_cfg;
current14_cfg_t current14_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
current14_cfg_setup( &current14_cfg );
CURRENT14_MAP_MIKROBUS( current14_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == current14_init( &current14, &current14_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( CURRENT14_ERROR == current14_default_cfg ( &current14 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_printf( &logger, " Calibrating zero current offset in 5 seconds...\r\n" );
log_printf( &logger, " Make sure no current flows through the sensor during the calibration process.\r\n" );
for ( uint8_t cnt = 5; cnt > 0; cnt-- )
{
log_printf( &logger, " %u\r\n", ( uint16_t ) cnt );
Delay_ms ( 1000 );
}
if ( CURRENT14_ERROR == current14_calib_offset ( &current14 ) )
{
log_error( &logger, " Calibrate offset." );
for ( ; ; );
}
log_printf( &logger, " Offset calibration DONE.\r\n\n" );
log_printf( &logger, " Calibrating data resolution in 5 seconds...\r\n" );
log_printf( &logger, " Keep the load current set at 3A during the calibration process.\r\n" );
for ( uint8_t cnt = 5; cnt > 0; cnt-- )
{
log_printf( &logger, " %u\r\n", ( uint16_t ) cnt );
Delay_ms ( 1000 );
}
if ( CURRENT14_ERROR == current14_calib_resolution ( &current14, 3.0f ) )
{
log_error( &logger, " Calibrate resolution." );
for ( ; ; );
}
log_printf( &logger, " Data resolution calibration DONE.\r\n" );
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 ( CURRENT14_OK == current14_get_current ( &current14, &current ) )
{
log_printf ( &logger, " Current: %.3f A\r\n\n", current );
}
}

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.Current14

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.
