Library Description
You can find all the functions for controlling LED lighting in the file Click_LED_Driver5_pwm
Key functions:
uint32_t leddriver5_pwmInit(uint16_t freq) - PWM init functionvoid leddriver5_pwmSetDuty(uint16_t duty) - PWM set duty functionvoid leddriver5_pwmStart() - PWM start functionvoid leddriver5_pwmStop() - PWM stop functionExamples description
The application is composed of the three sections :
void applicationTask()
{
_dutyCycle += 250;
leddriver5_pwmSetDuty(_dutyCycle);
if (_dutyCycle > 10000 )
{
_dutyCycle = 0;
leddriver5_pwmSetDuty(_dutyCycle);
Delay_ms(2000);
}
Delay_ms( 100 );
}

Additional notes and information
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.
