Firmware for the ultrasound modem
First untested version of the combined sender/reciever firmware. Uses RTC based timing synchronisation. Also uses the RadioHead library instead of the obsolete VirtualWire library.
buddy_modem contains the latest combined firmware
#Old firmware for separate sender/reciever:
- recieverj is the standalone receiver, wired for display on a Nokia LCD
- transmitter is the standalone transmitter
Both use the VirtualWire library (superseded by the RadioHead library)
