Expand 13 Click is a compact add-on board that contains a multi-port I/O expander. This board features the PI4IOE5V96248, a 48-bit general-purpose I/O expander providing remote I/O expansion for most MCU’s families from Diodes Incorporated. The PI4IOE5V96248 comes in a 6-channel configuration and allows easy addition of I/O through a standard I2C serial interface. It has a built-in level shifting feature that makes it highly flexible in power supply systems where communication between incompatible I/O voltages is required.

Click library

  • Author : Stefan Filipovic
  • Date : Oct 2021.
  • Type : I2C type

Software Support

We provide a library for the Expand13 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Expand13 Click driver.

Standard key functions :

  • expand13_cfg_setup Config Object Initialization function.

    void expand13_cfg_setup ( expand13_cfg_t *cfg );
  • expand13_init Initialization function.

    err_t expand13_init ( expand13_t *ctx, expand13_cfg_t *cfg );

Example key functions :

  • expand13_enable_device This function enables the device by setting the RST pin to high logic state.

    void expand13_enable_device ( expand13_t *ctx );
  • expand13_write_all_ports This function writes a desired data to all 6 ports.

    err_t expand13_write_all_ports ( expand13_t *ctx, uint8_t *ports );
  • expand13_read_all_ports This function reads the state of all 6 ports.

    err_t expand13_read_all_ports ( expand13_t *ctx, uint8_t *ports );

Example Description

This example demonstrates the use of Expand 13 Click board, by writing data to all six ports and then reading back the status of the ports.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the Click board.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    expand13_cfg_t expand13_cfg;  /**< Click config object. */

    /** 
     * 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.
    expand13_cfg_setup( &expand13_cfg );
    EXPAND13_MAP_MIKROBUS( expand13_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == expand13_init( &expand13, &expand13_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    expand13_enable_device ( &expand13 );
    log_info( &logger, " Application Task " );
}

Application Task

Sets the pins of all ports and then reads and displays their status on the USB UART approximately once per second.


void application_task ( void )
{
    uint8_t port_value[ 6 ] = { 0 };
    uint16_t pin_num = 0;

    for ( pin_num = EXPAND13_PIN_0_MASK; pin_num <= EXPAND13_PIN_7_MASK; pin_num <<= 1 )
    {
        if ( !expand13_get_int_pin ( &expand13 ) )
        {
            log_printf( &logger, " External input has occurred.\r\n" );
        }

        memset ( port_value, pin_num, 6 );
        expand13_write_all_ports( &expand13, port_value );

        expand13_read_all_ports( &expand13, port_value );
        for ( uint8_t cnt = EXPAND13_PORT_0; cnt <= EXPAND13_PORT_5; cnt++ )
        {
            log_printf( &logger, " Status port %d : 0x%.2X\r\n", ( uint16_t ) cnt, ( uint16_t ) port_value[ cnt ] );
        }
        log_printf( &logger, "\n" );
        Delay_ms ( 1000 );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Expand13

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. UART terminal is available in all MikroElektronika compilers.

Angle 6 Click is a compact add-on board that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft. This board features the MAQ470GQE, a 12-bit contactless angle sensor with PWM output from Monolithic Power Systems. It supports a wide range of magnetic field strengths and spatial configurations, with both end-of-shaft and off-axis (side-shaft mounting), supported configurations. Fast data acquisition and processing provides accurate angle measurement at speeds from 0 to 60,000 rpm, alongside magnetic field strength detection with programmable thresholds.
