MUX 4 Click

MUX 4 Click is a compact add-on board that contains a precise analog multiplexing IC. This board features the 74HC4851, 8-channel analog multiplexer/demultiplexer with injection-current effect control from Nexperia USA Inc.

Click library

  • Author : Stefan Filipovic
  • Date : Jul 2021.
  • Type : ADC type

Software Support

We provide a library for the MUX4 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 MUX4 Click driver.

Standard key functions :

  • mux4_cfg_setup Config Object Initialization function.

    void mux4_cfg_setup ( mux4_cfg_t *cfg );
  • mux4_init Initialization function.

    err_t mux4_init ( mux4_t *ctx, mux4_cfg_t *cfg );

Example key functions :

  • mux4_read_an_pin_voltage This function reads results of AD conversion of the AN pin and converts them to proportional voltage level.

    err_t mux4_read_an_pin_voltage ( mux4_t *ctx, float *data_out );
  • mux4_enable_input This function enable or disables analog inputs.

    void mux4_enable_input ( mux4_t *ctx, uint8_t en_state );
  • mux4_select_input This function selects which input channel signal is being forwarded to the AN/EXT pin.

    void mux4_select_input ( mux4_t *ctx, uint8_t input );

Example Description

This example demonstrates the use of MUX 4 Click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables analog inputs.


void application_init ( void )
{
    log_cfg_t log_cfg;    /**< Logger config object. */
    mux4_cfg_t mux4_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 );
    Delay_ms ( 100 );
    log_info( &logger, " Application Init " );

    // Click initialization.

    mux4_cfg_setup( &mux4_cfg );
    MUX4_MAP_MIKROBUS( mux4_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == mux4_init( &mux4, &mux4_cfg ) )
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }

    mux4_enable_input( &mux4, MUX4_ENABLE_INPUT );
}

Application Task

Reads the voltage from all input channels and displays the values of each channel on the USB UART approximately every second.


void application_task ( void )
{
    float mux4_an_voltage = 0;

    for ( uint8_t cnt = MUX4_SELECT_INPUT_1; cnt <= MUX4_SELECT_INPUT_8; cnt++ )
    {
        mux4_select_input( &mux4, cnt );
        Delay_ms ( 10 );
        if ( ADC_ERROR != mux4_read_an_pin_voltage ( &mux4, &mux4_an_voltage ) ) 
        {
            log_printf( &logger, " CH%u Voltage : %.3f V\r\n", ( uint16_t ) cnt, mux4_an_voltage );
        }
    }
    log_printf( &logger, " ----------------------------\r\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.MUX4

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.

TFT Proto 7in - Example

5

TFT Proto 7in carries a 800x480 HT050AWV40T TFT screen covered with a 4-wire resistive touchscreen panel. To drive the 262k-color display, there's an SSD1963 graphic controller with a 8/9/16/24-bit MCU interface. The touchpanel is driven by an advanced STMPE811 controller. TFT Proto 7in uses a 3.3V power supply only.
