Library Description

The library covers all the necessary functions to control IR Beacon Click board.
IR Beacon Click communicates with the target board via PWM module.
This library contains drivers for enabling or disabling PWM and for enabling, disabling or reseting MOD.

Key functions:

• void irbeacon_enablePwm(); - Function enables the PWM by seting PWM pin.
• void irbeacon_enableMod();- Function enables the device by seting MOD pin.
• void irbeacon_resetMod(); - Function resets the device.

Examples description

The application is composed of three sections:

• System Initialization - Initializes GPIO structure, sets AN and PWM pins as output.
• Application Initialization -  Enables GPIO and PWM, sets the frequency and duty cycle and enables PWM.
• Application Task - (code snippet) This is a example which demonstrates the use of IR Beacon Click board. It shows how to enable the device and gradualy increase the duty cycle.

void applicationTask() 
{
    irbeacon_enableMod();
    
    for ( dutyCycle = 250; dutyCycle < 3000; dutyCycle += 250 )
    {
        irbeacon_pwmSetDuty( dutyCycle );
        Delay_ms( 500 );
    }
    
    irbeacon_disableMod();
    Delay_ms( 1000 );
}

Additional notes and informations

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
