Ammeter Click is a mikroBUS add-on board with circuitry for measuring electric current (both AC and DC).
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.
This library contains API for Ammeter Click driver.
Config Object Initialization function.
void ammeter_cfg_setup ( ammeter_cfg_t *cfg );
Initialization function.
AMMETER_RETVAL ammeter_init ( ammeter_t ctx, ammeter_cfg_t cfg );
float ammeter_amperage ( ammeter_t *ctx );
Demo app measures and displays current by using Ammeter Click board.
The demo application is composed of two sections :
Initalizes SPI, LOG and Click drivers.
void application_init ( void )
{
log_cfg_t log_cfg;
ammeter_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_printf( &logger, "---- Application Init ----\r\n" );
// Click initialization.
ammeter_cfg_setup( &cfg );
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" );
}
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 );
}
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.
