RadioCountToLeds

RadioCountToLeds is a simple radio broadcast demo application. It runs a 4 Hz counter and broadcasts the value every time it is updated. When the application hears a packet from another node, it displays the value from the packet using its LEDs. The number of displayed bits depends on the number of LEDs on a particular platform (max 8). The application is intended to test and demonstrate how the system is set up, how threads, timers and the radio work.

The application is compatible with the TinyOS RadioCountToLeds application and protocol, it has been briefly tested against an IRIS node.

Work in progress

The application mainly demonstrates radio functionality on top of the MistComm API, but the MistComm API still has some issues and therefore the way it is used will change before the 1.0 release. Keep checking this exaple app to keep up with changes and improvements.

Platforms

The application has been tested and should work with the following platforms:

  • Thinnect TestSystemBoard0 (tsb0)
  • Thinnect TestSystemBoard2 (tsb2)
  • SiLabs Thunderboard Sense (thunderboard)
  • SiLabs Thunderboard Sense 2 (thunderboard2)
  • SiLabs BRD4001A + BRD4161A (brd4161a-mb)
  • SiLabs BRD4001A + BRD4162A (brd4162a-mb)
  • SiLabs BRD4001A + BRD4304A (brd4304a-mb)

TODO Series2 boards:

  • SiLabs BRD4001A + BRD4180A (brd4180a-mb)

Build

Standard build options apply, check the main README. Additionally the device address can be set at compile time, see the next chapter for details.

Device address / signature

Devices are expected to carry a device signature using the format specified in https://github.com/thinnect/euisiggen and https://github.com/thinnect/device-signature. The device then derives a short network address using the lowest 2 bytes of the EUI64 contained in the signature.

If the device does not have a signature, then the application will initialize the radio with the value defined with DEFAULT_AM_ADDR. For example to set the address to 0xABCD in the firmware for a Thunderboard Sense 2, make can be called make thunderboard2 DEFAULT_AM_ADDR=0xABCD. It is necessary to call make clean manually when changing the DEFAULT_AM_ADDR value as the buildsystem is unable to recognize changes of environment variables.
