Ambient 18 Click

Ambient 18 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.


Click Library

  • Author : Stefan Filipovic
  • Date : Dec 2021.
  • Type : ADC/I2C type

Software Support

Example Description

This example demonstrates the use of Ambient 18 Click board by measuring and displaying the illuminance value in Lux.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Ambient18

Example Key Functions

Application Init

Initializes the driver and sets the gain mode to M-Gain which can detect the illuminance of up to 1000 lux.

void application_init ( void )
{
log_cfg_t log_cfg;
ambient18_cfg_t ambient18_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
ambient18_cfg_setup( &ambient18_cfg );
AMBIENT18_MAP_MIKROBUS( ambient18_cfg, MIKROBUS_1 );
err_t init_flag = ambient18_init( &ambient18, &ambient18_cfg );
if ( ( ADC_ERROR == init_flag ) || ( I2C_MASTER_ERROR == init_flag ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
log_printf( &logger, " M-Gain mode selected.\r\n Up to 1000 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 ( AMBIENT18_OK == ambient18_read_voltage ( &ambient18, &voltage ) )
{
log_printf( &logger, " Illuminance : %ld Lux\r\n\n", ambient18_voltage_to_lux( &ambient18, voltage ) );
Delay_ms ( 1000 );
}
}

Application Output

This Click board can be interfaced and monitored in two ways:

  • Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
  • UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
