  • Page 3: Introduction

    Introduction The CC2400 single-chip RF transceiver provides a highly integrated, flexible low-cost solution for applications using the world wide unlicensed 2.4 GHz frequency band. The CC2400DBK demonstration board kit is a complement to the development kit (DK) as the hardware is representative of an actual application, and it is well suited as a prototyping platform for application code.

Figure 2: Antenna dimensions The height of the antenna is defined as the distance from the ground plane to the parallel section, and the length is from the end of the antenna parallel section to the feed point.
  • Page 6 The radiated pattern for the PCB antenna was measured with the horizontal polarization direction for the CC2400DB by measuring with vertical and horizontal mounting of the demonstration board. Important: In practical range testing outdoors with line-of-sight (LOS) and use of the rfBlinkLed application example, the following range has been verified at Chipcon Norway with optimal SmartRF Studio settings for the respective data rates: 1.

  • Page 8: Rs-232 Interface

    RS-232 interface A serial port is included on the CC2400DB. This port is used when software is programmed into the AVR MCU using the boot loader, and is also used by several of the example programs. The port includes support for RTS/CTS-type hardware flow control (handshaking). Important: It is important to be aware that maximum data rate for the Atmega8 RS-232 interface on CC2400DB is 38.4 Kbps due to the use of the internal RC oscillator.

  • Page 22: Using The Cc2400Db Demonstration Board

    Using the CC2400DB Demonstration Board The CC2400DB Demonstration Board is designed to be useful for quick prototyping, and also for quick practical evaluation such as range testing. Software can be programmed into the AVR microcontroller either using an external programmer such as the AVRISP programmer or using the serial port to communicate with the boot loader that is programmed into the MCU when the CC2400DB is shipped from the factory.

  • Page 23: Rc Oscillator

    Figure 13: AVR Studio AVRISP Fuses Window RC oscillator The internal RC oscillator is used as reference time base. The oscillator frequency is relatively independent of temperature and operating voltage. Its nominal frequency is 8 MHz. A calibration feature utilising a calibration word programmed into the microcontroller at the factory ensures that the oscillator frequency is equal from unit to unit.

The program code memory (flash) and the EEPROM can be reprogrammed. AVRISP Figure 14: AVRISP Program Window used to program flash or EEPROM The device used for programming must be connected to the CC2400DB programming socket.

  • Page 25: Bootloader

    Table 6: ISP header connector Bootloader The CC2400DB is shipped with a bootloader. This loader communicates with AVR Studio. After reset the bootloader must have a way to determine to start program mode or to run the application software residing in the application code section of the flash. To start the bootloader the Joystick center push on CC2400DB is used to enter program mode.

  • Page 26: Introduction To Examples Provided With Cc2400Db

    Figure 16: AVRprog bootloader Window In the bootloader window the user can browse to the location of his application program and program the application code section of the flash with the new application. After programming is successful, reset the processor and the application code will start. Important: If the AVRISP programmer is used to program examples, the bootloader will be deleted if no protection mode is applied to this section of the processor flash.

    specifically the compiler converts one or more C source files into assembly code, which, together with any handwritten assembler files are fed to the assembler. The assembler then produces object files (machine code and binary data), which in turn are fed into the linker together with the libraries and include files.

  • Page 28: Configure Output Profile

    • Utility.c Configure output profile The CC2400 Development Environment “build process” generates an executable file according to the settings specified in the make file provided with the application examples and by using the macros configured in the text editor. To support the processor target the output file must be in the correct format.

    Troubleshooting It does not work • Make sure that the power supply is connected to the correct pins on the power connector. • Is the supply voltage correctly polarized? If not, the protection diode will prevent any current from flowing. + and – are indicated on the PCB. On the DC jack, the tip is + and the ring is –.
