Click library

  • Author : Mihajlo Djordjevic
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Magneto 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 Magneto Click driver.

Standard key functions :

  • Config Object Initialization function.

    void magneto_cfg_setup ( magneto_cfg_t *cfg );

  • Initialization function.

    MAGNETO_RETVAL magneto_init ( magneto_t ctx, magneto_cfg_t cfg );

  • Click Default Configuration function.

    void magneto_default_cfg ( magneto_t *ctx );

Example key functions :

  • This function read and returns the value of the state register.

    uint16_t magneto_get_state ( magneto_t *ctx );

  • This function read the 16-bit data from register then calculate and convert to float angle value from 0deg to 360deg.

    float magneto_calculate_angle ( magneto_t *ctx );

Examples Description

Example presents precise angle measurements down to 0.05º in 14-bit resolution.

The demo application is composed of two sections :

Application Init

Application Init performs Logger and Click initialization.


void application_init ( void )
{
    log_cfg_t log_cfg;
    magneto_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_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, "     Application  Init\r\n" );
    Delay_ms ( 100 );

    //  Click initialization.

    magneto_cfg_setup( &cfg );
    MAGNETO_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    magneto_init( &magneto, &cfg );

    log_printf( &logger, "--------------------------\r\n" );
    log_printf( &logger, " ----- MAGNETO Click ---- \r\n" );
    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );

    if ( magneto_get_state( &magneto ) != 1 )
    {
        log_printf( &logger, " -- Initialization done --\r\n" );
    }
    else
    {
        log_printf( &logger, " -------- ERROR ! --------\r\n" );
    }

    log_printf( &logger, "--------------------------\r\n" );
    Delay_ms ( 1000 );
}

Application Task

Magneto Click communicates with register via SPI by write and read from register and calculate float angle value. Results are being sent to the UART Terminal where you can track their changes. All data logs on USB UART for aproximetly every 2 sec.


void application_task ( void )
{
    angle_value = magneto_calculate_angle( &magneto );
    log_printf( &logger, "  [ANGLE] : %0.3f \r\n", angle_value );

    Delay_ms ( 1000 );
    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.Magneto

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.

NFC Tag 5 Click

0

NFC Tag 5 Click is a compact add-on board that contains a compact NFC tag IC. This board features the M24LR64E-R, a dynamic NFC/RFID tag IC with a dual interface 64-Kbit EEPROM from STMicroelectronics. It features an I2C interface alongside an RF contactless interface operating at 13.56MHz, organized as 8192×8 bits in the I2C mode and 2048×32 bits in the ISO 15693 and ISO 18000-3 mode 1 RF mode. The M24LR64E-R also features an energy harvesting analog output and a user-configurable digital output pin, used as an interrupt, toggling during either RF write in progress or RF busy mode.
