Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : I2C type

Software Support

We provide a library for the VCTMonitor 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 VCTMonitor Click driver.

Standard key functions :

Example key functions :

Example Description

This is an example which demonstrates the use of VCT Monitor Click board.

The demo application is composed of two sections :

Application Init

Initialization driver enables the USB uart terminal and I2C.

void application_init ( void ) {
log_cfg_t log_cfg;
vctmonitor_cfg_t vctmonitor_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.
vctmonitor_cfg_setup( &vctmonitor_cfg );
VCTMONITOR_MAP_MIKROBUS( vctmonitor_cfg, MIKROBUS_1 );
err_t init_flag = vctmonitor_init( &vctmonitor, &vctmonitor_cfg );
if ( I2C_MASTER_ERROR == init_flag ) {
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

Reads temperature, current value, and differential voltage every 4 seconds.

void application_task ( void ) {
float temperature;
float voltage;
float current;
voltage = vctmonitor_read_voltage_differential( &vctmonitor );
log_printf( &logger, " Voltage : %.2f mV \r\n", voltage );
current = vctmonitor_read_current( &vctmonitor );
log_printf( &logger, " Current : %.2f mA \r\n", current );
temperature = vctmonitor_read_temperature( &vctmonitor );
log_printf( &logger, " Temperature: %.2f C \r\n", temperature );
log_printf( &logger, "- - - - - - - - - - - -\r\n" );
Delay_ms( 4000 );
}

Note

We used the next sets for the test:

  • Power supply - 4V
  • Current (Load) - 0A to 3A
  • The temperature reads from the external MMBT3904 sensor

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.VCTMonitor

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.
