Compile issue

[heyezhi727]

There's an error that: #error Must include FastSerial.h before the Arduino serial driver is defined.
when compiling the project in Arduino 1.6.11. Could you please tell me how to fix it? I've tried several ways, but it still exists.

I have actually no idea. Try using a older version of arduino.

It wil compile in 1.0.5

I'd like to compile for Arduino Yun, the old version IDE can't support for this.

Take a look at this fork. He has made updates for later arduino versions https://github.com/t413/APM-Mavlink-to-FrSky
