Library Description

Library contains function for returnning INT pin state Library contains functions for getting and setting device register content Library contains function for updating data used to calculate ALS Lux value Library contains function for device initialization Library contains function for raw data to Lux converison Library contains functions for getting PS and ALS values Library contains functions for getting raw PS and ALS data Library contains functions for setting ALS and PS High and Low thresholds Library contains function for setting PS offset value

Key functions:

• void proximity11_update(void) - updates data used to calculate Lux
• uint8_t proximity11_init(void) - initializes the device
• void proximity11_getPsAlsValues( uint16_t * ps_value, float * als_value ) - gets raw ALS and PS data and converts raw ALS data to Lux value

Examples description

The application is composed of three sections :

• System Initialization - Initializes INT pin, I2C and LOG modules
• Application Initialization - Initializes I2C driver and performs device initialization
• Application Task - Gets ALS and PS values and logs those values

void applicationTask( )
{
    proximity11_getPsAlsValues( &ps_value, &als_value );

    WordToStr( ps_value, text );
    mikrobus_logWrite( "PS  : ", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " [count]", _LOG_LINE );

    FloatToStr( als_value, text );
    mikrobus_logWrite( "ALS : ", _LOG_TEXT );
    mikrobus_logWrite( text, _LOG_TEXT );
    mikrobus_logWrite( " [Lx]", _LOG_LINE );

    mikrobus_logWrite( " ", _LOG_LINE );

    Delay_ms(500);
}

Other mikroE Libraries used in the example:

• I2C
• UART
• Conversions

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.
