Bandit @ 13:00 - Part 4 XBees (Plus Extra :- EPP Flying practice)
August 15, 2010
Project "Depron" took one leap forward , with the successful implementation of the XBee Pros and Servo mechanisms.
This is a key part of the project, which means that i can now rest easy that i have 1.5Kms of control over the plane.
It was no easy task to find compatible libraries for the Serial & Servo control,
In the end a combo of the NewSoftSerial.h and ServoTimer1.h was the perfect match for the XBee Pros, the whole system is running rock steady @ 38400Baud (@momo).
EDIT:- Patrick Mcabe just pointed out ServoTimer1.h only drives 2 servos (oversight on my side)..............oh man the search continues for libraries for driving serial port and 5 pwms..........
I am currently testing it to its limits...... so far so good ............
Now i can press on with the Rudder - Elevator servos mechanisms.
I have also made the motor mount ,rather novel - it was my way of making a secure supportive mount strong enough to retain the motor but at the same time flexible to align.
The Aeroplane in the Video is my sons EPP indestructable, its one of of my practice planes.
