Proximity 2 clickâ„¢ features MAX44000, an IC that integrates an ambient light as well as a proximity sensor. The IR proximity detector is matched with an integrated IR LED driver (for the onboard high power infrared LED). Proximity 2 clickâ„¢ communicates with the target board microcontroller through mikroBUS I2C (SCL, SDA), and INT lines.

Library Description
The library initializes and defines the I2C bus driver and drivers that offer a choice for writing and reading
data in and from registers. The library includes a functions for reading interrupt state, main configuration,
receive configuration, transmit configuration, ambient light and proximity registers. It allows to it's user
many diferent setings and set ups in order tu make full usage of its capabilities.
Key functions:
uint8_t proximity2_readProxDataReg();- Function is used to read prox data register in order to get data on distance from sensor to an object.Examples description
The application is composed of three sections:
void applicationTask()
{
proxiVal = proximity2_readProxDataReg();
ambient = proximity2_readAlsDataRegs();
if ( ( ( proxiVal - proxiValOld ) > sensitivity ) || ( ( proxiValOld - proxiVal ) > sensitivity ) )
{
mikrobus_logWrite( " Distance : ", _LOG_TEXT );
IntToStr( proxiVal, txt );
Ltrim( txt );
mikrobus_logWrite( txt, _LOG_LINE );
mikrobus_logWrite( " Light : ", _LOG_TEXT );
IntToStr( ambient, txt );
Ltrim( txt );
mikrobus_logWrite( txt, _LOG_LINE );
mikrobus_logWrite( "-------------------", _LOG_LINE );
proxiValOld = proxiVal;
Delay_ms( 1 );
}
}

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
