As subject says - is there a rule of thumb when moving to AC2? should I start with the PID values from the Pirates NG version, or start from scratch with the defaults? AndrewContinue

Camera Stab Pitch not moving

I have an APM 1280 running 2.5.x and the pitch output (5) seems not to work. Roll is OK - I can move the copter and the servo will respond. Pitch does nothing however. Interestingly, if I change the CAM_P_TRIM parameter, the pitch servo will move. So it is not the servo, not the output. It just does not respond to changing the pitch of the copter.Channel 6 on the TX does nothing either.Am I missing something?See More

Bluetooth Serial Communications with the APM

Posted on September 17, 2011 at 1:46pm 41 Comments

I've heard some people mention using bluetooth to communicate with microcontrollers as replacement for a serial or USB & FTDI. Recently some small bluetooth serial modules have become available from large electronics retailers and smaller ones that operate on large internet auction websites. They can be purchased now for just a few bucks. The module has all the bluetooth components integrated and takes 3 volt TTL level RS232 signals. It comes in a surface mountable pcb package, however…

.Net Configurator screen shots

Screen shots after some sporadic work. Accel and TX calibration is working.

UI is a bit rude still, it's in Winforms. WPF is so much nicer, but can not run on Mono.
