Click library

  • Author : MikroE Team
  • Date : Sep 2020.
  • Type : I2C type

Software Support

We provide a library for the Expand6 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 Expand6 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void expand6_cfg_setup ( expand6_cfg_t *cfg );

  • Initialization function.

    EXPAND6_RETVAL expand6_init ( expand6_t ctx, expand6_cfg_t cfg );

Example key functions :

  • Set all OUTPUT pins' logic levels in one port function

    void expand6_write_port ( expand6_t *ctx, uint8_t port, uint8_t value );

  • Reset function

    void expand6_reset ( expand6_t *ctx );

  • Set a single OUTPUT pin's logic level function

    void expand6_write_pin ( expand6_t *ctx, uint16_t pin, uint8_t pin_val );

Examples Description

This example demonstrates the use of EXPAND 6 Click board.

The demo application is composed of two sections :

Application Init

Initalizes I2C driver and makes an initial log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    expand6_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_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    expand6_cfg_setup( &cfg );
    EXPAND6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    expand6_init( &expand6, &cfg );

    expand6_reset ( &expand6 );
    Delay_ms ( 1000 );

    log_printf( &logger, "------------------- \r\n" );
    log_printf( &logger, "   EXPAND 6 Click   \r\n" );
    log_printf( &logger, "------------------- \r\n" );
}

Application Task

This example shows the capabilities of the EXPAND 6 Click by toggling each of the 20 available pins.


void application_task ( void )
{
    expand6_write_port( &expand6, EXPAND6_PORT_0, 0xFF );
    expand6_write_port( &expand6, EXPAND6_PORT_1, 0xFF );
    expand6_write_port( &expand6, EXPAND6_PORT_2, 0xFF );

    log_printf( &logger, "All pins set to HIGH logic level!\r\n" );
    log_printf( &logger, "---------------------------------\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    for ( pin_num = 0; pin_num < 20; pin_num++ )
    {
        expand6_write_pin( &expand6, pin_num, EXPAND6_LOW );
        log_printf( &logger, "Pin %u is set to LOW logic level!\r\n", ( uint16_t) pin_num );
        Delay_ms ( 300 );
    }

    log_printf( &logger, "---------------------------------\r\n" );
    Delay_ms ( 1000 );
}

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.Expand6

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.

7x10 G Click is a LED dot matrix display Click, which can be used to display graphics or letters in a very simple and easy way. The Click board has two LED dot matrix modules with 7x5 stylish, round, dot-like LED elements. These displays produce clean and uniform patterns since the elements are optically isolated from each other and there is no light bleeding between the adjacent LED cells. Additionally, turn-on and turn-off times of the matrix cells are optimized for a clean and fluid display performance, with no flickering or lag.
