Hall Switch Click

Hall Switch Click is a magnetic field activated dual-relay Click board™. Hall Switch Click has two high-quality relays, which are activated by the Hall-effect sensor: when the north pole magnetic field is introduced to the sensor, one of the relays will be activated; when the south pole magnetic field is introduced to the sensor, the other relay will be activated.

Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the HallSwitch 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 HallSwitch Click driver.

Standard key functions :

  • Config Object Initialization function.

    void hallswitch_cfg_setup ( hallswitch_cfg_t *cfg );

  • Initialization function.

    HALLSWITCH_RETVAL hallswitch_init ( hallswitch_t ctx, hallswitch_cfg_t cfg );

  • Click Default Configuration function.

    void hallswitch_default_cfg ( hallswitch_t *ctx );

Example key functions :

  • Function for turn on and turn off N Pole

    void hallswitch_set_npole ( hallswitch_t *ctx, uint8_t state );

-Function for turn on and turn off S Pole

void hallswitch_set_spole ( hallswitch_t *ctx,uint8_t state );

Examples Description

The application sets sensor magnetic pole

The demo application is composed of two sections :

Application Init

Initializes Driver init and turn OFF S pole and N pole


void application_init ( void )
{
    log_cfg_t log_cfg;
    hallswitch_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.

    hallswitch_cfg_setup( &cfg );
    HALLSWITCH_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    hallswitch_init( &hallswitch, &cfg );

    hallswitch_set_npole( &hallswitch, HALLSWITCH_POLE_NO_ACTIVE );
    hallswitch_set_spole( &hallswitch, HALLSWITCH_POLE_NO_ACTIVE );
}

Application Task

Turns S and N on and off every 500 msInitializes Driver init and turn OFF S pole and N pole


void application_task()
{
    hallswitch_set_npole( &hallswitch, HALLSWITCH_POLE_ACTIVE );
    Delay_ms ( 500 );
    hallswitch_set_spole( &hallswitch, HALLSWITCH_POLE_ACTIVE );
    Delay_ms ( 500 );
    hallswitch_set_npole( &hallswitch, HALLSWITCH_POLE_NO_ACTIVE );
    Delay_ms ( 500 );
    hallswitch_set_spole( &hallswitch, HALLSWITCH_POLE_NO_ACTIVE );
    Delay_ms ( 500 );
}

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.HallSwitch

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.

Secure 3 click

1

Secure 3 click carries the ATSHA204A, a cryptographic coprocessor with secure hardware-based key storage from Microchip. The click is designed to run on either 3.3V or 5V power supply. Secure 3 click communicates with the target microcontroller over an I2C interface.

RTC 2 click

0

Example for RTC2 click board in mikroBUS form factor. It is a simple demonstration how to read/write date and time from DS1307 RTC (real-time clock). Date and time are read from the RTC every 10 milliseconds and printed on LCD. Communication with the board is done via I2C interface.

AC Current Click

0

AC Current Click is a device that is able to measure the alternating current (AC) running through the conductor, using the so-called non-invasive current sensor. The non-invasive sensor works by utilizing the electromagnetic induction phenomenon, similar to a transformer. The primary coil does not exist though, the electromagnetic field is generated by the AC Current running through the cable which is measured. The core of the sensing probe is split, allowing it to clamp on the current conducting cable. Since the sensor does not influence the measurement circuitry in any way while being galvanically isolated at the same time, it is an ideal solution to measure current running through mains, or similar high voltage installations.
