UV click

Design devices that warn you of excesive ultraviolet radiation levels with UV click. This click boards carries the ML8511 IC that is sensitive to UV-A (365-315 nm) and UV-B (315-280 nm) rays.

Click library

  • Author : Nenad Filipovic
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Uv 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.

Library Description

This library contains API for Uv Click driver.

Standard key functions :

  • Config Object Initialization function.

    void uv_cfg_setup ( uv_cfg_t *cfg );

  • Initialization function.

    UV_RETVAL uv_init ( uv_t *ctx, uv_cfg_t *cfg );

  • Click Default Configuration function.

    void uv_default_cfg ( uv_t *ctx );

Example key functions :

  • Read 12-bit UV data function.

    uint16_t uv_read_data ( uv_t *ctx );

  • Set power mode function.

    void uv_set_poewr_mode ( uv_t *ctx, uint8_t pwr_en );

Examples Description

This is a example which demonstrates the use of UV Click board.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.

void application_init ( void )
{
log_cfg_t log_cfg;
uv_cfg_t cfg;
// Logger initialization.
log_cfg.level = LOG_LEVEL_DEBUG;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_printf( &logger, "- Application Init -\r\n" );
// Click initialization.
uv_cfg_setup( &cfg );
UV_MAP_MIKROBUS( cfg, MIKROBUS_1 );
uv_init( &uv, &cfg );
uv_default_cfg ( &uv );
Delay_ms( 100 );
log_printf( &logger, "--------------------\r\n" );
log_printf( &logger, " UV Click\r\n" );
log_printf( &logger, "--------------------\r\n" );
}

Application Task

This is a example which demonstrates the use of UV Click board. Reads 12-bit UV data. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart is changed for every 5 sec.

void application_task ( void )
{
uint16_t uv_data;
uv_data = uv_read_data ( &uv );
log_printf( &logger, " UV : %4d\r\n", uv_data );
log_printf( &logger, "--------------------\r\n" );
Delay_ms( 5000 );
}

Note

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:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Uv

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.
