APC220 radio.

This apc220 interface and configuration library is based on a simple C class

It is based on use of SoftwareSerial so on a UNO the hardware serial port is available or other things.

On a cansat it could be like

• hardware serial for logging data on sdcard

  • higher baudrate than for radio to log large amount of data

  • 57600 which gives 5000 bytes to log pr second

• software serial for telemetri back to your homebase

  • 9600 baud or lower (lower for extending range)

  • a few hundred bytes pr second

Still beware of your databudgets. Dont use all CPU power and time for logging

If you have a MEGA there is 4 hardware serial ports. In that case you can modify library to just use a hardware serial port.

Changing frequency on radio

The library provide a simple interface for reprogram the apc220
