Click library

  • Author : Nenad Filipovic
  • Date : Dec 2019.
  • Type : GPIO type

Software Support

We provide a library for the Reed 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 Reed Click driver.

Standard key functions :

  • Config Object Initialization function.

    void reed_cfg_setup ( reed_cfg_t *cfg );

  • Initialization function.

    REED_RETVAL reed_init ( reed_t ctx, reed_cfg_t cfg );

  • Click Default Configuration function.

    void reed_default_cfg ( reed_t *ctx );

Example key functions :

  • Get magnetic detected status function.

    uint8_t reed_get_status ( reed_t *ctx );

Examples Description

This is a example which demonstrates the use of REED Click board.

The demo application is composed of two sections :

Application Init

Configuring clicks and log objects.


void application_init ( void )
{
    log_cfg_t log_cfg;
    reed_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, "- Application Init -\r\n");

    //  Click initialization.

    reed_cfg_setup( &cfg );
    REED_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    reed_init( &reed, &cfg );

    reed_state = REED_NO_MAGNETIC_FIELD;
    reed_state_old = REED_NO_MAGNETIC_FIELD;

    log_printf(&logger, "--------------------\r\n");
    log_printf(&logger, "     REED Click\r\n");
    log_printf(&logger, "--------------------\r\n");
    Delay_100ms();
}

Application Task

Detect the magnetic field near the REED Click. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart when magnetic field is detected.


void application_task ( void )
{
    reed_state = reed_get_status( &reed );

    if ( ( reed_state == REED_MAGNETIC_FIELD_DETECTED ) && ( reed_state_old == REED_NO_MAGNETIC_FIELD ) )
    {
        reed_state_old = REED_MAGNETIC_FIELD_DETECTED;
        log_printf(&logger, "     ~ LOCKED ~\r\n");
        log_printf(&logger, "--------------------\r\n");
    }

    if ( ( reed_state == REED_NO_MAGNETIC_FIELD ) && ( reed_state_old == REED_MAGNETIC_FIELD_DETECTED ) )
    {
        log_printf(&logger, "    ~ UNLOCKED ~\r\n");
        log_printf(&logger, "--------------------\r\n");
        reed_state_old = REED_NO_MAGNETIC_FIELD;
    }
} 

Note

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.Reed

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.

eFuse Click

0

Fuse Click is a compact add-on board that contains a programmable electronic power breaker. This board features the STPW12, an integrated electronic power breaker optimized to monitor the input power from STMicroelectronics. Connected in series to the power rail, it can disconnect the electronic circuitry on its output if the power consumption overcomes the programmed limit. The intervention of the protection is communicated to the MCU through a signal on the fault pin. The device can also be enabled/disabled through a dedicated Enable pin with a direct PWM mode, which can be achieved through an external PWM signal.

Light 2 Click

0

Light 2 Click is a compact add-on board designed for accurate and flexible light measurement in various environments. This board features the ISL76682, a high-sensitivity, light-to-digital sensor with an I2C interface from Renesas, made specifically for automotive applications. Key features include a photodiode array that closely mimics the human eye's response, an ADC for flicker rejection, and four selectable light measurement ranges via I2C, enhancing both flexibility and accuracy. With a typical power consumption of 55µA in Standard mode and two power-down modes to minimize energy use, the board is efficient and adaptable to different lighting conditions.
