Ambient 10 Click is a compact add-on board used to sense the amount of the present ambient light. This board features the APDS-9006-020, analog-output ambient light photosensor from Broadcom Limited.
We provide a library for the Ambient10 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.
This library contains API for Ambient10 Click driver.
ambient10_cfg_setup
Config Object Initialization function.
void ambient10_cfg_setup ( ambient10_cfg_t *cfg );
ambient10_init
Initialization function.
err_t ambient10_init ( ambient10_t *ctx, ambient10_cfg_t *cfg );
ambient10_set_vref
This function sets the voltage reference for Ambient 10 Click driver.
err_t ambient10_set_vref ( ambient10_t *ctx, float vref );
ambient10_read_adc_voltage
This function reads raw 12-bit ADC data and converts it to voltage by using I2C serial interface.
err_t ambient10_read_adc_voltage ( ambient10_t *ctx, float *voltage );
ambient10_voltage_to_lux
This function calculates illuminance (lux) based on the voltage input.
uint16_t ambient10_voltage_to_lux ( ambient10_t *ctx, float voltage );
This example demonstrates the use of Ambient 10 Click board.
The demo application is composed of two sections :
Initializes the driver and sets the voltage reference.
void application_init ( void )
{
log_cfg_t log_cfg; /**< Logger config object. */
ambient10_cfg_t ambient10_cfg; /**< Click config object. */
/**
* 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 );
Delay_ms ( 100 );
log_info( &logger, " Application Init " );
// Click initialization.
ambient10_cfg_setup( &ambient10_cfg );
AMBIENT10_MAP_MIKROBUS( ambient10_cfg, MIKROBUS_1 );
if ( ADC_ERROR == ambient10_init( &ambient10, &ambient10_cfg ) )
{
log_error( &logger, " Application Init Error. " );
log_info( &logger, " Please, run program again... " );
for ( ; ; );
}
ambient10_set_vref( &ambient10, AMBIENT10_VREF_3V3 );
log_info( &logger, " 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 ( AMBIENT10_OK == ambient10_read_an_pin_voltage ( &ambient10, &voltage ) )
{
log_printf( &logger, " Illuminance : %u Lux\r\n\n", ambient10_voltage_to_lux( &ambient10, 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.

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.
