I am trying to setup a UDB4 for my electric A10 Warthog. I have the new code downloaded, compiled and installed. I have all the electronics including the radio and servos setting on my bench. After powerup I get the double wag of the servo and I believe it's trying to get GPS lock, but since I'm inside it probably can't see the GPS satellites very well (if at all).
My question is - will I be able to switch on stabilized mode and see the servos try to correct if there is no GPS lock? As it sits right now, after the initial servo wag (after 10 seconds), the green LED is on, all the radio controls work the servos (through the UDB4), but if I switch on stabilize and move the UDB4 around I don't get any servo movement. I'm hoping that it's just from the lack of GPS lock.
I recently got a UDB4 and am trying to program it for the first time using a Pickit3. I have been following the "UAV DevBoard: Getting Started with PIC Programming" guide but have run into problems when trying to build..... First off I hadn't changed the #define in the options.h which was giving me a failed build. Now however I am getting the following error:
c:\program files\microchip\mplab c30\bin\bin\..\bin/pic30-coff-ld.exe: cannot find -legacy-libc Link step failed. ---------------------------------------------------------------------- Release build of project `C:\Documents and Settings\Rich\Desktop\MatrixPilot_3_2_1\MatrixPilot\MatrixPilot-udb4.mcp' failed.

Im interested in the UAVDevBoard solely for a camera tracker. Im running a full autopilot on a helicopter and I would like to use the UAVDevBoard as a stand alone unit to track. Can anyone tell me what I'll need to implement it?
@Dave, Hi. Yes, I had that problem once.In MPLAB under "Configure / Select Device", select "dsPIC33FJ256GP710A". Be careful to select the right one ! .
It will then load the correct libraries for the UDB4.
I ended up installing UDB in my fairly new Multiplex Mentor. I flew the plane with UDB in stabilized mode for the first time this afternoon. I couldn't be more pleased with how the flight went. The Mentor is already a good plane, and with UDB it is rock solid. Very stable. Good product, guys.
Pete, I followed the steps you recommended. Everything seems to be in operational order. My first time through was a little confusing, but I just followed the programming guide and the notes I took. No error messages during the build. Now I need to install it in a plane and start ground tests. Thanks for all the advice.
All of my hardware has now arrived: UDBv3, EM-406A, OpenLog, and PicKit2. I installed MPLAB and the C compiler with no problems. I doubt I'll get to the actual hardware setup this week, because I still have a lot of reading of user guides to do. However, I don't recall seeing anything yet that states whether all components should be attached before initializing UDB, or if the process should be done by initializing UDB first, then add one component at a time. Any recommendations?
Doing a bit of reading in the UDB instructions last night. After installing the Pic drivers, it said to power up UDB before plugging the programmer into UDB. I thought I had read somewhere that UDB can get its power from the PicKit USB connection. I'm still searching the forums and wiki, but Is there a preferred method?
I think I messed up. My new UAV DevBoard arrived today. I didn't read deep enough into the instruction site before buying the GPS, and I ordered the D2523T from Sparkfun, thinking it was OK because it also used the u-Blox 5 engine. Then I saw that it wasn't supported, but the u-Blox 407 is. Unfortunately, everyone seems to be out of the u-Blox 407, and some of the comments I've read about the EM-406 say it has a slow response time. Does the D2523T absolutely not work with the DevBoard? If not, I'll have to get an RMA and send the D2523T back. And if I have to do that, which would be a better replacement, EM-406 or Mediatek?

Dear William Premerlani,
Could LPR430L and LPY330ALH gyros and MAA7361 accelero be used in Gentlenav ( UAVDEVboard) ?
Thanks in advance with best regards
