Current 12 Click

Current 12 Click is a compact add-on board designed for high-precision monitoring of current, voltage, power, and temperature in various applications. This board features the TSC1641, a 60V 16-bit power monitor with an I2C interface from STMicroelectronics. The TSC1641 consist of a high-precision 16-bit dual-channel sigma-delta ADC, capable of measuring high-side, low-side, and bidirectional currents with a programmable conversion time ranging from 128µs to 32.7ms. It supports 2-wire I2C communication with clock frequencies up to 1MHz, and includes an alert interrupt pin for setting thresholds on voltage, current, power, and temperature.

Software Support

We provide a library for the Current 12 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 12 Click driver.

Example Description

This example demonstrates the use of the Current 12 Click board by reading and displaying the input current measurements.

The demo application is composed of two sections :

Application Init

The initialization of the I2C module and log UART. After driver initialization, the app sets the default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
current12_cfg_t current12_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
current12_cfg_setup( &current12_cfg );
CURRENT12_MAP_MIKROBUS( current12_cfg, MIKROBUS_1 );
if ( I2C_MASTER_ERROR == current12_init( &current12, &current12_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( CURRENT12_ERROR == current12_default_cfg ( &current12 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
log_printf( &logger, "_____________________\r\n " );
Delay_ms ( 100 );
}

Application Task

The demo application reads and displays the results of the input current, voltage, and power measurements. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
float meas_data = 0;
if ( CURRENT12_OK == current12_get_shunt_voltage( &current12, &meas_data ) )
{
log_printf( &logger, " Shunt Voltage: %.2f [mV]\r\n ", meas_data );
Delay_ms ( 100 );
}
if ( CURRENT12_OK == current12_get_load_voltage( &current12, &meas_data ) )
{
log_printf( &logger, " Load Voltage: %.2f [V]\r\n ", meas_data );
Delay_ms ( 100 );
}
if ( CURRENT12_OK == current12_get_dc_power( &current12, &meas_data ) )
{
log_printf( &logger, " DC Power: %.2f [W]\r\n ", meas_data );
Delay_ms ( 100 );
}
if ( CURRENT12_OK == current12_get_current( &current12, &meas_data ) )
{
log_printf( &logger, " Current: %.2f [mA]\r\n", meas_data );
Delay_ms ( 100 );
}
log_printf( &logger, "_____________________\r\n " );
Delay_ms ( 1000 );
Delay_ms ( 1000 );
}

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.

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Current12

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.
