I am working on a project where I use an arduino uno in the loop with a rc receiver feeding information into it, then the uno is sending information into an APM 2.5 autopilot to control a drone.
The first approach i was using involved code that used pulseIn to read the pwm from the receiver and it worked but was very sloppy.
So we switched over to interrupts and I used some example code to read the rc controller and the readings were beautiful. http://rcarduino.blogspot.com/2012/01/how-to-read-rc-receiver-with.html
The next step was I wanted to read multiple channels and be able to control the drone again using my rc controller going through the uno. I found this project and it looked good I just needed to make some small tweaks for my application. http://rcarduino.blogspot.com/2012/04/how-to-read-multiple-rc-channels-draft.html
The problem I am having is this uses a library and I have downloaded and installed the proper library, but it's not working. I try to compile and i get " 'PCintPort' has not been declared ". I've also noticed that when I try to put the library in the code with the drop down menu it just puts a blank space in there instead. I tested other libraries and they will put in the lines of code in properly (ex. #include <EEPROM.h>).
So does anyone have any idea what is going on here? I am very confused, I've tried using both the latest stable IDE and the beta. Deleted the library and installed different versions. I'm at a loss.
