Click library

  • Author : Luka Filipovic
  • Date : Nov 2019.
  • Type : SPI type

Software Support

We provide a library for the Magneto4 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 Magneto4 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void magneto4_cfg_setup ( magneto4_cfg_t *cfg );

  • Initialization function.

    MAGNETO4_RETVAL magneto4_init ( magneto4_t ctx, magneto4_cfg_t cfg );

  • Click Default Configuration function.

    void magneto4_default_cfg ( magneto4_t *ctx );

Example key functions :

  • Get Magnetic measurement status

    uint8_t magneto4_get_magnetic_status ( magneto4_t ctx, mag_status_t mag_status );

  • Encoder position

    void magneto4_get_encoder_position ( magneto4_t *ctx );

  • Encoder direction

    uint8_t magneto4_get_encoder_direction ( magneto4_t ctx, mag_status_t mag_status );

Examples Description

Reads and logs magnetic field strength values if magnetic field strength values bigger than 3000, start magnetic linear position mode,
when moving the sensor from left to right the position for 1 step is reduced.

The demo application is composed of two sections :

Application Init

Initializes Driver init and sets start encoder position on the zero. Reads and logs magnetic field strength values. For starting an encoder, it is necessary that the magnetic field strength is greater than 3000.


void application_init ( void )
{
    log_cfg_t log_cfg;
    magneto4_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.

    magneto4_cfg_setup( &cfg );
    MAGNETO4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    magneto4_init( &magneto4, &cfg );

    magneto4_default_cfg ( &magneto4 );

    log_printf( &logger, " --- Please, bring the magnet close ---\r\n" );

    while ( magnetic_field < MAGNETO4_MAX_MAGNETIC_FIELD_VALUE )
    {
        magnetic_field = magneto4_get_magnetic_field( &magneto4 );
        log_printf( &logger, " Magnetic field strength : %d\r\n", magnetic_field );
        Delay_ms ( 1000 );
    }

    Delay_ms ( 1000 );
    Delay_ms ( 500 );
    log_printf( &logger, " --- Magnetic Linear Position ---\r\n" );
}

Application Task

When moving the sensor from left to right, one step is added and when moving from right to left, the position for 1 step is reduced.


void application_task ( void )
{
    //  Task implementation.

    magneto4_get_encoder_position( &magneto4 );

    enc_position = magneto4.encoder_position;

    if ( old_position != enc_position )
    {
        log_printf( &logger, " Encoder position : %d\r\n", enc_position );
        log_printf( &logger, " ------------------------\r\n" );
    }

    old_position = enc_position;
}  

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.Magneto4

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.

GSR click can be used to measure the electrodermal activity (EDA) of the human body, also known as the galvanic skin response (GSR). EDA is actually the property of the human body that causes continuous variation in the electrical characteristics of the skin.

Thermo K 3 Click

0

Thermo K 3 Click is a compact add-on board that provides accurate temperature measurements with a thermocouple probe. This board features the MAX6675, a cold-junction-compensated K-thermocouple-to-digital converter from Analog Devices. With the versatile type-K probe, this board enables precise temperature measurements of up to +700°C in 12-bit (0.25°C) resolution. This board can measure temperatures as high as +1024°C but with less precision. It features cold-junction compensation sensing and correction and open thermocouple detection.
