Software Support

We provide a library for the Opto_3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

The library performs the input state checking and the output state setting. For more details check documentation.

Key functions :

• T_OPTO3_STATE opto3_getIN1( void ) - Function returns a state of the Input 1.
• void opto3_setOUT2( T_OPTO3_SWITCH state ) - Function puts the Output 2 to the desired state.
• -

Examples Description

The application is composed of three sections :

• System Initialization - Initializes peripherals and pins.
• Application Initialization - Initializes GPIO interface.
• Application Task - (code snippet) - Switches ON or switches OFF the both outputs depending on the states of the inputs, respectively. Note : Input state is active low, and output state is active high.

void applicationTask()
{
    stateIN1 = opto3_getIN1();
    stateIN2 = opto3_getIN2();
    
    stateOUT1 = stateIN1 ^ 1;
    stateOUT2 = stateIN2 ^ 1;
    
    opto3_setOUT1( stateOUT1 );
    opto3_setOUT2( stateOUT2 );
}

The full application code, and ready to use projects can be found on our LibStock page.

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.
