AVR beacon
A hamradio beacon project on an AVR MCU
... text to send it to the air. Transmission rates and modes are configurable from the input text. AVR beacon can read an external digital instruments like (voltmeter, thermometer, axelerometer, anemometer, etc.) and send its data to the air.
Beacons network is planned to implement using an external GPS module for time syncronization.
This project runs on Atmel AVR pico-power Mega microcontrollers: ATmega48p, ATmega88p, ATmega168p and ATmega368p. It is possible to port it to other AVR MCUs as well.
