UV 4 click is a powerful Ultra Violet (UV) sensing device and Ambient Light Sensor (ALS) Click board, featuring a sensor with a very wide dynamic range of detectable light intensity, across two ADC range settings.
We provide a library for the UV4 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 UV4 Click driver.
void uv4_cfg_setup ( uv4_cfg_t *cfg );
void uv4_default_cfg ( uv4_t *ctx );
UV4_RETVAL uv4_write_reg ( uv4_t* ctx, const uint8_t reg_address, const uint8_t transfer_data );
UV4_RETVAL uv4_read_reg ( uv4_t* ctx, uint8_t reg_address, uint8_t* data_out, uint8_t inc_en, uint8_t n_bytes );
UV4_RETVAL uv4_write_param_data ( uv4_t* ctx, uint8_t param_address, uint8_t transfer_data );
Reads all configured measurements from selected channels and logs results every 500ms.
The demo application is composed of two sections :
Initializes driver, performs reset command and enables selected channels.
Reads all configured measurements from selected channels and logs results every 500ms.
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.
