Click library

  • Author : Stefan Filipovic
  • Date : Apr 2024.
  • Type : ADC/I2C type

Software Support

We provide a library for the Current 11 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 11 Click driver.

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.

void application_init ( void )
{
log_cfg_t log_cfg;
current11_cfg_t current11_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
current11_cfg_setup( &current11_cfg );
CURRENT11_MAP_MIKROBUS( current11_cfg, MIKROBUS_1 );
err_t init_flag = current11_init( &current11, &current11_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
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" );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
{
log_error( &logger, " Calibrate offset." );
for ( ; ; );
}
log_printf( &logger, " 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 ( CURRENT11_OK == current11_read_current ( &current11, &current ) )
{
log_printf( &logger, " Current : %.1f A\r\n\n", current );
Delay_ms ( 1000 );
}
}

Note

For better accuracy, set the voltage reference by using the current11_set_vref function,

increase the number of conversions by modifying the CURRENT11_NUM_CONVERSIONS macro, and adjust the CURRENT11_COUPLING_FACTOR_G_A value.

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.Current11

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.
