Click library

Software Support

We provide a library for the Ammeter 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.

Library Description

This library contains API for Ammeter Click driver.

Standard key functions :

Example key functions :

Examples Description

Demo app measures and displays current by using Ammeter click board.

The demo application is composed of two sections :

Application Init

Initalizes SPI, LOG and click drivers.

void application_init ( void )
{
log_cfg_t log_cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "---- Application Init ----\r\n" );
// Click initialization.
AMMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
ammeter_init( &ammeter, &cfg );
log_printf( &logger, "-----------------------\r\n" );
log_printf( &logger, " Ammeter Click \r\n" );
log_printf( &logger, "-----------------------\r\n" );
}

Application Task

This is an example that shows the capabilities of the Ammeter click by

measuring amperage in miliampers. Ammeter click board can be used to saftly measure current up to 1A both AC and DC, in the case of AC, for peak to peak value.

void application_task ( void )
{
amperage = ammeter_amperage( &ammeter );
log_printf( &logger, " Current: %.2f mA \r\n", amperage );
log_printf( &logger, "-----------------------\r\n" );
Delay_ms( 1000 );
}

Note

It is important to notice that this click board has its' own electronic

circuit, and may not be powered from the same source which we are measuring. Result will not be correct in that case.

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.
