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 function

• void leddriver5_pwmSetDuty(uint16_t duty) - PWM set duty function

• void leddriver5_pwmStart() - PWM start function

• void leddriver5_pwmStop() - PWM stop function

Examples description

The application is composed of the three sections :

• System Initialization - Sets PWM pin as OUTPUT
• Application Initialization - Initialization driver init and pwm init
• Application Task - (code snippet) - Controls the brightness of the LED using PWM

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.
