UVC Click
UVC Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description
This Click is capable of measuring UVC spectrum in the range of 220nm up to 280nm and light intensity from 0mW/cm² up to 9.3mW/cm². With high sensitivity and good solar blindness, it can be used for monitoring sterilization lamps.
Example Libraries
- MikroSDK.Board
- MikroSDK.Log
- Click.Uvc

Application Init
Initializes the driver.
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
}

Application Task
Reads sensor raw data and calculates voltage and power of UVC light. The measured values will be displayed on the USB UART every 1500 ms.
{
uint16_t raw_data;
float voltage;
float power;
log_printf( &logger, "Raw data: %d\r\n", raw_data );
log_printf( &logger, "Voltage: %.4f mV\r\n", voltage );
log_printf( &logger, "Power: %.4f mW/cm2\r\n", power );
log_printf( &logger, "----------------------\r\n" );

Application Output
This Click board can be interfaced and monitored in two ways:
- Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
- UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.
Additional Notes and Information
The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
