Following the MoteinoMEGA release, the RFM69 library and examples have been updated to support MoteinoMEGA, there are significant changes to the library and you should get latest. The MoteinoMEGA Arduino Core has been released and needs to be installed in the Arduino/hardware folder (stable v1.0.5 tested working) before uploading to MoteinoMega. The Eagle source and schematic/board files are published in the LowPowerLab github repository. The Moteino page was updated to reflect the addition of the MEGA to the Moteino family.
The Wireless Programming library and examples are updated to fix bugs and support the MEGA as well. Another important change is the introduction of radio.ACKRequested() function in the RFM69 lib which should be used instead of the radio.ACK_REQUESTED variable. This ensures that ACKs requested by a broadcaster are ignored and only targeted ACKs are responded to. Please update your examples for proper wireless programming behavior. All examples have been updated to reflect this change. Also the SwitchMote sketch has been updated.
I consider this a major release and hence your constructive feedback and notification about anything that was omitted is appreciated.
