6.9.4 Transceiver Features

This module provides framework to access hardware features supported by Atmel transceivers that are not reflected in 802.15.4 standard.

Follow these steps in order to configure and add this module to the project:

  • Click on the checkbox near the 'Transceiver Features' module on the panel on the left hand side to enable this module to be added to the project

  • Select one or more options shown on the right hand side panel. Selecting an option adds the relevant functions to the generated code.

    • Read Voltage - a function to read the transceiver supply voltage is added to the project

    • Read Temperature - a function to read the temperature value from the transceiver's integrated sensor

    • Continuous Transmission - a function to start/end continuous transmission is added to the project. Continuous Transmission Test Mode supports final application / production tests as well as certification tests. Using this test mode the radio transceiver transmits continuously a previously transferred frame (PRBS mode) or a continuous wave signal (CW mode). In CW mode two different signal frequencies per channel can be transmitted:

      • f1 = fCH + 0.5MHz

      • f2 = fCH - 0.5MHz

      Here fCH is the channel center frequency programmed by register 0x08 (PHY_CC_CCA). Note, in CW mode it is not possible to transmit an RF signal directly on the channel center frequency. PSDU data in the Frame Buffer must contain at least a valid PHR followed by PSDU data. It is recommended to use a frame of maximum length (127 bytes) and arbitrary PSDU data for the PRBS mode. The SHR and the PHR are not transmitted. The transmission starts with the PSDU data and is repeated continuously.
