Light Temp Click
Light Temp 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.

Application Task
This is an example that demonstrates the use of the Light Temp Click board. This example shows the automatic control of the LED light intensity, the first intensity of light is rising and then the intensity of light is falling. Results are being sent to the Usart Terminal where you can track their changes.
{
static int8_t duty_cnt = 1;
static int8_t duty_inc = 1;
float duty = duty_cnt / 10.0;
log_printf( &logger, "Duty: %d%%\r\n", ( uint16_t )( duty_cnt * 10 ) );
Delay_ms ( 500 );
if ( 10 == duty_cnt )
{
duty_inc = -1;
}
else if ( 0 == duty_cnt )
{
duty_inc = 1;
}
duty_cnt += duty_inc;
}
void lighttemp_led1_pwm_start(lighttemp_t *ctx)
Start PWM module for LED1.
void lighttemp_led2_pwm_start(lighttemp_t *ctx)
Start PWM module for LED2.
void application_task(void)
Definition main.c:71
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.
