RF Meter click is a radio frequency power measurement device covering a frequency span from 1 MHz to 8 GHz over a 60 dB range. An external antenna acquires the signal, which is then processed by the AD8318 logarithmic detector. For communicating with the target board MCU, the mikroBUS SPI interface is used with additional TEMP OUT pin.

Library Description

The library covers all the necessary functions that enables the usage of the RF Meter click board.
It offers reading from output register and calculations that result in relatively accurate radio frequency signal strenght value.

Key functions:

  • uint16_t rfmeter_dataRead() - Function is used to read data from output register.
  • float rfmeter_getVoltage() - Function is used to read raw voltage value from output register.
  • float rfmeter_getSignalStrenght( float slope, float intercept ) - Function is used to calculate radio frequency signal strenght in a vicinity.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes SPI module, LOG and GPIO structures, sets CS pin as output and AN pin as input.
  • Application Initialization - Initalizes SPI driver and makes an initial log.
  • Application Task - (code snippet) This is an example that shows the capabilities of the RF Meter click by measuring radio frequency signal strenght.
void applicationTask( )
{
    signal = rfmeter_getSignalStrenght( _RFMETER_DEF_SLOPE, _RFMETER_DEF_INTERCEPT );
    
    mikrobus_logWrite( "Signal strenght: ", _LOG_TEXT );
    FloatToStr( signal, logTxt );
    mikrobus_logWrite( logTxt, _LOG_TEXT );
    mikrobus_logWrite( "dBm", _LOG_LINE );

    Delay_ms( 1000 );
    mikrobus_logWrite( "-----------------------", _LOG_LINE );
}

Other mikroE Libraries used in the example:

  • SPI
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.
