Serializer Click is a compact add-on board that contains a digital input translator/serializer. This board features the MAX31910, an eight-channel digital input serializer for high-channel density digital input modules in industrial and process automation from Analog Devices. The MAX31910 translates, conditions, and serializes the 24V digital output of sensors and switches to 5V CMOS-compatible signals required by the MCU. It provides the front-end interface circuit of a programmable logic controller (PLC) digital input module. It communicates with MCU via the SPI interface and comes in configuration with an installed digital isolator. This Click board™ is suited for various applications such as industrial, process, and building automation, digital input modules for PLCs, and more.

Click library

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

Software Support

We provide a library for the Serializer 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 Serializer Click driver.

Standard key functions :

  • serializer_cfg_setup Config Object Initialization function.

    void serializer_cfg_setup ( serializer_cfg_t *cfg );
  • serializer_init Initialization function.

    err_t serializer_init ( serializer_t *ctx, serializer_cfg_t *cfg );

Example key functions :

  • serializer_get_flt_pin This function returns the fault pin logic state.

    uint8_t serializer_get_flt_pin ( serializer_t *ctx );
  • serializer_read_input This function reads the input data by using SPI serial interface, and then checks the data integrity by verifying the CRC byte.

    err_t serializer_read_input ( serializer_t *ctx, uint8_t *data_out );

Example Description

This example demonstrates the use of a Serializer Click board by reading the state of all inputs and displaying the results on the USB UART.

The demo application is composed of two sections :

Application Init

Initializes the driver and logger.


void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    serializer_cfg_t serializer_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.
    serializer_cfg_setup( &serializer_cfg );
    SERIALIZER_MAP_MIKROBUS( serializer_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == serializer_init( &serializer, &serializer_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Reads the state of all inputs and displays the results on the USB UART approximately once per second. Also, if there's any fault indication detected, it will be displayed accordingly.


void application_task ( void )
{
    uint8_t input_data = 0;
    err_t status = serializer_read_input ( &serializer, &input_data );

    if ( SERIALIZER_ERROR != status )
    {
        for ( uint8_t cnt = 0; cnt < 8; cnt++ )
        {
            log_printf( &logger, " IN%u: %s\r\n", ( uint16_t ) cnt + 1, 
                                                  ( char * ) ( ( input_data & ( 1 << cnt ) ) ? "High" : "Low" ) );
        }
        if ( status & SERIALIZER_STATUS_UNDERVOLTAGE )
        {
            log_info( &logger, "Undervoltage fault" );
        }
        if ( status & SERIALIZER_STATUS_OVERTEMPERATURE )
        {
            log_info( &logger, "Overtemperature fault" );
        }
        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.Serializer

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.

HAPTIC 3 Click

0

Haptic 3 Click is a compact add-on board that uses advanced vibration patterns and waveforms to convey information to a user. This board features the DA7282, a linear resonant actuator (LRA), and an eccentric rotating mass (ERM) haptic driver from Dialog Semiconductor. The DA7282 features LRA or ERM drive capability with automatic closed-loop LRA resonant frequency tracking, guaranteeing consistency across LRA production tolerances. It also offers wideband operation that fully utilizes the capabilities of newer wideband and multi-directional LRAs, alongside three external general-purpose inputs for triggering up to six independent haptic sequences.

Is there such a thing as the Ballmer peak? It's the idea that moderate alcohol consumption has a benefitial impact on creativity, and hence, on programming ability. The theory was explained in this issue of the xkcd webcomic. We devised a practical test to examine the validity of the assumption.
