Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

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

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for IrEclipse Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ireclipse_cfg_setup ( ireclipse_cfg_t *cfg );

  • Initialization function.

    IRECLIPSE_RETVAL ireclipse_init ( ireclipse_t ctx, ireclipse_cfg_t cfg );

  • Click Default Configuration function.

    void ireclipse_default_cfg ( ireclipse_t *ctx );

Example key functions :

  • Detecting states of IR beam from EE-SX198 photo interrupter sensor.

    uint8_t ireclipse_int_status ( ireclipse_t *ctx );

Examples Description

This is an example of IR ECLIPSE Click board.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.


void application_init ( void )
{
    log_cfg_t log_cfg;
    ireclipse_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_printf(&logger, "- Application Init -\r\n");

    //  Click initialization.

    ireclipse_cfg_setup( &cfg );
    IRECLIPSE_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ireclipse_init( &ireclipse, &cfg );
    log_printf( &logger, "--------------------\r\n" );
    log_printf( &logger, "   Start counting:  \r\n" );
    log_printf( &logger, "--------------------\r\n" );

    n_cnt = IRECLIPSE_START_CNT_VAL;
    state_old = IRECLIPSE_LOW;
    state_new = IRECLIPSE_LOW;
}

Application Task

This is a example which demonstrates the use of IR eclipse Click board. When the beam from the transmitter is eclipsed by placing an object in the gap ( like a piece of paper ), when the sensor is triggered, the counter is incremented by one. Results are being sent to the Usart Terminal where you can track their changes. Data logs on usb uart when the sensor is triggered.


void application_task ( void )
{
    state_new = ireclipse_int_status( &ireclipse );

    if ( ( state_new == IRECLIPSE_HIGH ) && ( state_old == IRECLIPSE_LOW ) )
    {
        state_old = IRECLIPSE_HIGH;
        log_printf( &logger, "  Counter = %d \r\n", n_cnt );

        n_cnt++;
    }

    if ( ( state_new == IRECLIPSE_LOW ) && ( state_old == IRECLIPSE_HIGH ) )
    {
        log_printf( &logger, "--------------------\r\n" );
        state_old = IRECLIPSE_LOW;
    }
}  

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.IrEclipse

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.
