We provide a library for the Proximity7 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 Proximity7 Click driver.
Config Object Initialization function.
void proximity7_cfg_setup ( proximity7_cfg_t *cfg );
Initialization function.
PROXIMITY7_RETVAL proximity7_init ( proximity7_t ctx, proximity7_cfg_t cfg );
Click Default Configuration function.
void proximity7_default_cfg ( proximity7_t *ctx );
Get proximity data.
uint16_t proximity7_get_proximity_data( proximity7_t *ctx )
Get lux level.
float proximity7_get_lux_level( proximity7_t *ctx )
Set proximity offset
uint8_t proximity7_set_proximity_offset( proximity7_t *ctx, uint8_t proximity_offset_magnitude )
This application give us lux level and proximiti data.
The demo application is composed of two sections :
Initializes I2C driver and writes basic settings to device registers
void application_init ( void )
{
log_cfg_t log_cfg;
proximity7_cfg_t cfg;

- When setting LED drive strength please note that if "proximity drive level - PDL" bit in "configuration register" is set to 1, LED drive current values are reduced by 9.
- When setting wait time note that if "wait long - WLONG" bit is set to 1, time is 12x longer. Therefore if WLONG == 1 set time between 33ms and 8386.56ms.
- When setting ALS gain note that if "ALS gain level - AGL" bit is set to 1, ALS gains are scaled by 0.16, otherwise, they are scaled by 1.
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.
