Click library

  • Author : Katarina Perendic
  • Date : okt 2019.
  • Type : I2C/SPI type

Software Support

We provide a library for the 3dHall5 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 3dHall5 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void c3dhall5_cfg_setup ( c3dhall5_cfg_t *cfg );

  • Initialization function.

    C3DHALL5_RETVAL c3dhall5_init ( c3dhall5_t ctx, c3dhall5_cfg_t cfg );

  • Click Default Configuration function.

    void c3dhall5_default_cfg ( c3dhall5_t *ctx );

Example key functions :

  • Axis data

    int16_t c3dhall5_get_axis_data ( c3dhall5_t *ctx, uint8_t axis );

  • Set offest

    void c3dhall5_set_offset ( c3dhall5_t *ctx, uint8_t offset_axis, int16_t offset );

  • Interrupt state

    uint8_t c3dhall5_get_interrupt_state ( c3dhall5_t *ctx );

Examples Description

The Demo application displays and reads 3 magnetic axes.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects. Reads device ID for check communication.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c3dhall5_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.

    c3dhall5_cfg_setup( &cfg );
    C3DHALL5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c3dhall5_init( &c3dhall5, &cfg );

    c3dhall5_default_cfg ( &c3dhall5 );

    device_id = c3dhall5_get_device_id ( &c3dhall5 );
    log_info( &logger, "** Device ID: 0x%x", device_id );
}

Application Task

Reads the magnetics X / Y / Z axis data every 1 seconds.

void application_task ( void )
{
    int16_t axis_X;
    int16_t axis_Y;
    int16_t axis_Z;

    //  Task implementation.

    axis_X = c3dhall5_get_axis_data( &c3dhall5, C3DHALL5_AXIS_X );
    axis_Y = c3dhall5_get_axis_data( &c3dhall5, C3DHALL5_AXIS_Y );
    axis_Z = c3dhall5_get_axis_data( &c3dhall5, C3DHALL5_AXIS_Z );

    log_printf( &logger, "----- AXIS -----\r\n" );
    log_printf( &logger, "** X: %d \r\n", axis_X );
    log_printf( &logger, "** Y: %d \r\n", axis_Y );
    log_printf( &logger, "** Z: %d \r\n", axis_Z );
    log_printf( &logger, "----------------\r\n" );

    Delay_ms ( 1000 );
}

Note

Default communication that is set is I2C communication. If you want to use SPI, you have to set up the cfg structure.

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.3dHall5

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.

Microwave 5 Click

0

Microwave 5 Click is a compact add-on board that utilizes the Doppler Shift Phenomenon to sense motion. This board features the PD-V10-G5, a miniature X-band microwave transceiver from Ningbo Pdlux Electronic Technology. The transmitter on this transceiver works on a 10.525GHz frequency over the patch antenna, with a 2-4kHz pulse repetition frequency. The strength of the sensor’s output, in other words, the detection range, depends on the Signal-to-Noise ratio.
