Click library

  • Author : Jovan Stajkovic
  • Date : Dec 2019.
  • Type : SPI type

Software Support

We provide a library for the Rfmeter 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 Rfmeter Click driver.

Standard key functions :

  • Config Object Initialization function.

    void rfmeter_cfg_setup ( rfmeter_cfg_t *cfg );

  • Initialization function.

    RFMETER_RETVAL rfmeter_init ( rfmeter_t ctx, rfmeter_cfg_t cfg );

Example key functions :

  • Function is used to calculate radio frequency signal strenght in a vicinity.

    float rfmeter_get_signal_strenght ( rfmeter_t *ctx, float slope, float intercept );

Examples Description

Demo app measures and displays signal strenght by using RF Meter Click board.

The demo application is composed of two sections :

Application Init

Initalizes SPI, LOG and Click drivers.


void application_init ( void )
{
    log_cfg_t log_cfg;
    rfmeter_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 ----" );

    //  Click initialization.

    rfmeter_cfg_setup( &cfg );
    RFMETER_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    rfmeter_init( &rfmeter, &cfg );
    log_printf( &logger, "----------------------- \r\n" );
    log_printf( &logger, "    RF Meter Click      \r\n" );
    log_printf( &logger, "----------------------- \r\n" );
}

Application Task

This is an example that shows the capabilities of the RF Meter Click by measuring radio frequency signal strenght.


void application_task ( void )
{
    signal = rfmeter_get_signal_strenght( &rfmeter, RFMETER_DEF_SLOPE, RFMETER_DEF_INTERCEPT );

    log_printf( &logger, "Signal strenght: %.2f dBm \r\n", signal );

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

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.Rfmeter

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.

POT 4 Click is a compact add-on board with accurate selectable reference voltage output. This board features the PRS11R-425F-S103B1, a high-quality 11mm rotary 10k potentiometer from Bourns. The PRS11R-425F-S103B1 features a small form factor, offers an push-on momentary switch, a flatted shaft style, and a wide operating temperature range. It comes with a high-resolution 12-bit ADC, detecting even the slightest move while digitizing its position, alongside a rail-to-rail buffering operational amplifier, which provides constant input and output impedance. Besides, the user can process the output signal in analog or digital form.
