Click library

  • Author : Stefan Filipovic
  • Date : Jul 2021.
  • Type : ADC type

Software Support

We provide a library for the Ambient12 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 Ambient12 Click driver.

Standard key functions :

Example key functions :

Example Description

This example demonstrates the use of Ambient 12 click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the gain mode to M-Gain which can detect the illuminance of up to 10000 lux.

void application_init ( void )
{
log_cfg_t log_cfg;
ambient12_cfg_t ambient12_cfg;
// Logger initialization.
LOG_MAP_USB_UART( log_cfg );
log_cfg.level = LOG_LEVEL_DEBUG;
log_cfg.baud = 115200;
log_init( &logger, &log_cfg );
Delay_ms( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
ambient12_cfg_setup( &ambient12_cfg );
AMBIENT12_MAP_MIKROBUS( ambient12_cfg, MIKROBUS_1 );
if ( ADC_ERROR == ambient12_init( &ambient12, &ambient12_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
log_printf( &logger, " M-Gain mode selected.\r\n Up to 10000 lux can be measured.\r\n" );
log_info( &logger, " Application Task " );
}

Application Task

Reads the ADC voltage and then calculates the illuminance from it. The calculated value of illuminance in lux is being displayed on the USB UART approximately once per second.

void application_task ( void )
{
float voltage = 0;
if ( AMBIENT12_OK == ambient12_read_adc_voltage ( &ambient12, &voltage ) )
{
log_printf( &logger, " Illuminance : %ld Lux\r\n\n", ambient12_voltage_to_lux( &ambient12, voltage ) );
}
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.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ambient12

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.
