Proximity 2 Click features MAX44000, an IC that integrates an ambient light as well as a proximity sensor. The chip consists of an array of photodiodes that convert light into current, which the internal circuitry then converts into a digital value.

Proximity 2 Click features MAX44000, an IC that integrates an ambient light as well as a proximity sensor. The chip consists of an array of photodiodes that convert light into current, which the internal circuitry then converts into a digital value.
We provide a library for the Proximity2 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for Proximity2 Click driver.
Config Object Initialization function.
void proximity2_cfg_setup ( proximity2_cfg_t *cfg );
Initialization function.
PROXIMITY2_RETVAL proximity2_init ( proximity2_t ctx, proximity2_cfg_t cfg );
Click Default Configuration function.
void proximity2_default_cfg ( proximity2_t *ctx );
Read PROX Data Register function.
uint8_t proximity2_read_prox ( proximity2_t *ctx );
Read ALS Data Registers function.
uint16_t proximity2_read_als ( proximity2_t *ctx );
This is an example that shows the most important functions that Proximity 2 Click has.
The demo application is composed of two sections :
Configuring clicks and log objects. Setting the Click in the default configuration.
void application_init ( void )
{
log_cfg_t log_cfg;
proximity2_cfg_t cfg;
/**
* 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 );
log_info( &logger, "Application Init" );
// Click initialization.
proximity2_cfg_setup( &cfg );
PROXIMITY2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
proximity2_init( &proximity2, &cfg );
proximity2_default_cfg ( &proximity2 );
log_info( &logger, "Application Init" );
Delay_ms ( 1000 );
}
Shows the most important proximity and ambient value.
void application_task ( void )
{
proxi_val = proximity2_read_prox ( &proximity2 );
ambient = proximity2_read_als ( &proximity2 );
log_printf( &logger, " Distance : %d \r\n", (uint16_t)proxi_val );
log_printf( &logger, " Light : %d \r\n", ambient );
log_printf( &logger, "------------------\r\n" );
Delay_ms ( 300 );
}
The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
