Click library

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

Software Support

We provide a library for the Expand7 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 Expand7 Click driver.

Standard key functions :

  • expand7_cfg_setup Config Object Initialization function.

    void expand7_cfg_setup ( expand7_cfg_t *cfg ); 
  • expand7_init Initialization function.

    err_t expand7_init ( expand7_t *ctx, expand7_cfg_t *cfg );

Example key functions :

  • expand7_reset Reset function

    void expand7_reset ( expand7_t *ctx );
  • expand7_write_all Set all OUTPUT pins' logic levels function

    void expand7_write_all ( expand7_t *ctx, uint8_t value );
  • expand7_write_pin Set a single OUTPUT pin's logic level function

    void expand7_write_pin ( expand7_t *ctx, uint8_t pin, uint8_t pin_val );

Examples Description

This example demonstrates the use of the EXPAND 7 Click.

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;
    expand7_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.
    expand7_cfg_setup( &cfg );
    EXPAND7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    expand7_init( &expand7, &cfg );
    Delay_ms ( 100 );

    log_printf( &logger, "------------------- \r\n" );
    log_printf( &logger, "   EXPAND 7 Click   \r\n" );
    log_printf( &logger, "------------------- \r\n" );
}

Application Task

This example shows the capabilities of the EXPAND 7 Click by toggling each of the 40 available pins.


void application_task ( void )
{
    expand7_write_all ( &expand7, 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 ( uint8_t pin_num = 0; pin_num < 40; pin_num++ )
    {
        expand7_write_pin( &expand7, pin_num, EXPAND7_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.Expand7

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.
