Proximity 3 click is an intelligent proximity and light sensing device, which features the VCNL4200 sensor from Vishay - high sensitivity long distance proximity sensor (PS), ambient light sensor (ALS) and 940 nm IRED, all in one small package.
We provide a library for the Proximity3 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 Proximity3 Click driver.
void proximity3_cfg_setup ( proximity3_cfg_t *cfg );
PROXIMITY3_RETVAL proximity3_init ( proximity3_t *ctx, proximity3_cfg_t *cfg );
void proximity3_default_cfg ( proximity3_t *ctx );
void proximity3_generic_write ( proximity3_t *ctx, uint8_t reg_address, uint16_t data_in );
uint16_t proximity3_generic_read ( proximity3_t *ctx, uint8_t reg_address );
uint16_t proximity3_read_ambient_light_sensor ( proximity3_t *ctx );
This example reads the data from the ambient light sensor and converts the data into digital form using calculations.
The demo application is composed of two sections :
Initialization driver enables - I2C, initializes VCNL4100, write configuration register and starts to write log to Usart Terminal.
This is a example which demonstrates the use of Proximity 3 Click board. Measured distance ( proximity ) and illuminance ( abmient light ) from sensor, results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for aproximetly every 3 sec.
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.
Other mikroE Libraries used in the example:
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.
