I have been wanting to use Adafruit's servo and TFT library, but whenever I upload example sketches, it always says that yield was not declared in this scope. I know that this is in the Intel Edison troubleshooting, but I cannot type out functions that are already in a library. Please help!
Are you talking about Arduino Sketch? or some thing specific to Edison?
Post the program so we can see what you can see.
And please use the code button </>
so your code looks like thisand is easy to copy to a text editor
Did you select Edison as your upload target on the Tools menu? Did you install the i686 boards via the boards manager?
