Current 2 Click is an accurate current sensing Click board™ suitable for a very accurate measurement of the current through the load.
We provide a library for the current2 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for current2 Click driver.
Config Object Initialization function.
void current2_cfg_setup ( current2_cfg_t *cfg );
Initialization function.
CURRENT2_RETVAL current2_init ( current2_t ctx, current2_cfg_t cfg );
Get ADC function
uint16_t current2_get_adc ( current2_t *ctx );
Get Averaged ADC function
uint16_t current2_get_average_adc ( current2_t *ctx, uint8_t n_samp );
Get Current function
uint16_t current2_get_current ( current2_t *ctx, uint8_t n_sample );
This application measures current.
The demo application is composed of two sections :
Initializes SPI interface in Mode 0
void application_init ( void )
{
log_cfg_t log_cfg;
current2_cfg_t cfg;
/**
* Logger initialization.
* Default baud rate: 115200
* Default log level: LOG_LEVEL_DEBUG
* @note If USB_UART_RX and USB_UART_TX
* are defined as HAL_PIN_NC, you will
* need to define them manually for log to work.
* See @b LOG_MAP_USB_UART macro definition for detailed explanation.
*/
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
current2_cfg_setup( &cfg );
CURRENT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
current2_init( ¤t, &cfg );
Delay_ms ( 300 );
log_printf( &logger, "Current 2 is initialized \r\n \r\n" );
}
Reads the current averaged result of 20 samples and gets this result in a proper value [mA]. Repeats the current reading every 500ms.
void application_task ( void )
{
uint16_t tmp;
tmp = current2_get_current( ¤t, 20 );
log_printf( &logger, "Current : %d mA \r\n", tmp );
Delay_ms ( 500 );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
