Usage of serial ports in ATMega 1280

Posted by Chinab Chugh on May 27, 2011 at 10:36am

In an ATMega 1280 Autopilot controller (as in the full kit in the store), where are the 4 UART serial ports being used:

 

I know that one must be for USB, then maybe one for the IMU sensor. I am using one for Xbee as well. So, I was wondering whether there is still one free?

 

My intention is to communicate with another microcontroller and was thinking of ways to do this. I dont intend on using the SPI as of now.

 

Thanks All.

    Hi Chinab,

    Did you ever figure out how to get APM to communicate with another processor?  I want to do the same thing.

    Serial0 USB

    Serial1 GPS

    Serial2 DataLogging (Flash) 

    Serial3 Telemetry

    See the recent post regarding sharing telemetry port with xbee and Remzibi OSD, you may be able to use the same type of setup.
