Introduction ============ This is a spectrum sensing application for the VESNA platform. It presents a unified interface to different radiofrequency energy detection modules through a serial terminal. It also serves as an example use of hardware drivers using the low-level spectrum sensing API. All spectrum sensing devices supported by this application work by tuning to a radiofrequency channel and estimating the power level at the antenna interface. The range of frequencies that can be sensed is determined by a hardware configuration. Each device may support one or more configurations. A configuration is characterized by the frequency of the bottom-most channel, channel spacing, channel bandwidth, number of channels and the time it takes the device to perform a measurement for a single channel. Currently the following hardware models are supported (selectable via the MODEL environment variable when invoking make): - sne-crewtv VESNA SNC + SNE-CREWTV hardware configuration wide-band energy detection in the UHF band using NXP TDA18219HN tuner (also requires proprietary libtda18219 VESNA library) - sne-ismtv-uhf VESNA SNC + SNE-ISMTV-UHF hardware configuration wide-band energy detection in the UHF band using NXP TDA18219HN tuner (also requires proprietary libtda18219 VESNA library) - sne-ismtv-868 VESNA SNC + SNE-ISMTV-868 hardware configuration energy detection in the 868 MHz ISM band using Texas Instruments CC1101. - snr-trx-868 VESNA SNC + SNR-TRX-868 hardware configuration energy detection in the 868 MHz ISM band using Texas Instruments CC1101. - sne-ismtv-2400 VESNA SNC + SNE-ISMTV-2400 hardware configuration energy detection in the 2.4 GHz ISM band using Texas Instruments CC2500. - snr-trx-2400 VESNA SNC + SNR-TRX-2400 hardware configuration energy detection in the 2.4 GHz ISM band using Texas Instruments CC2500. - null VESNA SNC hardware configuration dummy software-only device, returning noise and zero measurements For more info on VESNA, see http://sensorlab.ijs.si/hardware.html Compilation =========== To compile and upload firmware to a VESNA using OpenOCD and Olimex ARM-USB-OCD: $ make MODEL=sne-crewtv spectrum-sensor.u Set the MODEL variable to the name of the hardware model you are using. If you want to run the application using the VESNA bootloader, add "LDSCRIPT=vesna_app.ld" to the make command-line. Usage ===== Connect VESNA to a serial terminal using 115200 baud, 8 data bits, 1 stop bit, no parity. You can then use the terminal to interact with the application in a command-line fashion (conclude each command with a new line) Type "help" to print a list of available commands with brief descriptions. A typical session consists of: 1. "list" command to get the list of hardware configurations available 2. "select" command to select a configuration and setup the spectrum sweep parameters. 3. "report-on" command to start the sweep. 4. "report-off" command to stop the sweep. The python/ directory includes Python classes that abstract this interface. Please refer to the README in that directory for details.
