Parallax Propellar Auto Pilot

Posted by Earl on March 20, 2009 at 7:39am
Here is my code for the Parallax Propeller CPU using the guts of a Wii nun chuck as the accelerometer.The code is modified from Paul Huber's to use the nun chuck data.For a $15 accelerometer it works nice. Still worling on project.

    Earl: I looked at the pcb layout, you must have some 0.1uF caps to decouple the 5V supply, located
    right at the chip power and ground pins. Also a 10uF cap at least on the 5V. A ground plane helps a lot, too.

    CPU's will not work without these caps. Not reliably, at least.

    Here is the latest code with all the sensors working..
    Also what I will fly...
    And the first circuit board..

    The accelerometer alone is useless for aircraft tilt sensing in coordinated turn. Search more on the forum.

    This is my code for the barometer i2c module sdk500. It is written in spin code for the parallax propeller.

    Here is new code with a 'ping' ultrasonic altitude. I now need to integrate the compass and altitude module.
