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.
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.
This library contains API for Uv Click driver.
uv_cfg_setup
Config Object Initialization function.
void uv_cfg_setup ( uv_cfg_t *cfg );
uv_init
Initialization function.
err_t uv_init ( uv_t *ctx, uv_cfg_t *cfg );
uv_read_adc_voltage
ADC Voltage Reading function.
err_t uv_read_adc_voltage ( uv_t *ctx, float *data_out );
uv_calc_index
UV Index Calculation function.
void uv_calc_index ( uv_t *ctx, float data_in, uint8_t *data_out );
This is a example which demonstrates the use of UV Click board.
The demo application is composed of two sections :
Configuration of the Click and log objects.
void application_init ( void )
{
log_cfg_t log_cfg;
uv_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.
uv_cfg_setup( &cfg );
UV_MAP_MIKROBUS( cfg, MIKROBUS_1 );
if ( SPI_MASTER_ERROR == uv_init( &uv, &cfg ) )
{
log_info( &logger, "---- Application Init Error ----" );
log_info( &logger, "---- Please, run program again ----" );
for ( ; ; );
}
uv_set_callback_handler( &uv, application_callback );
uv_device_enable( &uv );
Delay_ms ( 1000 );
uv_voltage = 0;
uv_index = 0;
log_info( &logger, "---- Application Init Done ----\r\n" );
}
Reads the result of AD conversion once per second and calculates the UV index based on that. Results are being sent to the USB UART where you can track their changes.
void application_task ( void )
{
if ( SPI_MASTER_ERROR != uv_read_adc_voltage( &uv, &uv_voltage ) )
{
uv_calc_index( &uv, uv_voltage, &uv_index );
log_printf( &logger, " UV Index [0-15] : %u\r\n", ( uint16_t ) uv_index );
log_printf( &logger, " UV ADC Voltage [V] : %.2f\r\n", uv_voltage );
log_printf( &logger, "------------------------------\r\n" );
}
Delay_ms ( 1000 );
}
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.
