Library Description

The library carries functions necessary to have complete control over all functionalities of the Click board.

Examples Description

The demo application is composed of three sections:

  • System Initialization - Necessary registers and GPIO configuration.
  • Application Initialization - PWM Initizalization and Start of PWM signal.
  • Application Task - (code snippet) - Sequential change of the brightness from
    minimum to maximum value.
void applicationTask()
{
 dutyCycle += 50;
 PWM_TIM5_Set_Duty(dutyCycle, _PWM_NON_INVERTED, _PWM_CHANNEL1);
 if (dutyCycle > pwmPeriod )
 dutyCycle = 0;
 Delay_ms(2);
}

Other mikroE Libraries used in the example:

  • PWM

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.

Let's make - Breathalyser

Is there such a thing as the Ballmer peak? It's the idea that moderate alcohol consumption has a benefitial impact on creativity, and hence, on programming ability. The theory was explained in this issue of the xkcd webcomic. We devised a practical test to examine the validity of the assumption.
