About Me:
Previously into "antweight" robots making all my own hardware and software , mostly using Microchip PICs programmed in C. Now having a go at UAVs - starting with an Easystar.
Please tell us a bit about your UAV interest

"Yes this is lots of fun Doug. If anyone else is too impatient to wait for Doug's code to be avaialble there is a version of source code which will run on Ardupilot (orignal) hardware to receive the remote control channels from a DSM2 Satellite…"
"There was a discussion on this device, including code a while ago here:
http://www.diydrones.com/profiles/blogs/store-updates-1
The code below has been tested using an Ardupilot PCB and includes the right device id etc for communications.
You do…"

"I2C level shifter (PCA9306) is a great find adn design, ideal for connecting the SCP1000-D11 to Ardupilot as it provides the 3V3 supply voltage as well as optimising the I2C communications. I've been getting away with running my whole Ardupilot…"
"Q4: As Doug has said there are plenty of threads on Easystar construction on RCGroups, possibly too many - How you feel about mounting the motor probably depends on how you have fixed the two halves of the body together. I've successfully used small…"
"Incredible "creatures" - we saw them today at the Gadget Show Live (NEC, UK), as in the video (which I guess was taken yesterday before the huge crowds were let in) and then in the Super Theatre show. They were being remote controlled due to…"
"ArduNXT (the poor relation of DIYDrones dev teams - as it is going rather slowly) which is setting out to provide a Lego Mindstorms NXT interface with Radio Contol and Servos based on an ArduPilot PCB is quite similar to your 4 channel servo…"

"I've been playing with the SCP1000-D11 for a few months using the official VTI breakout board, but connected to a Microchip PIC processor instead of an arduino. I've merged some code that I had already written, to track the chance in altitude, based…"
With a view to maximising the available processor power (cycles) available for further enhancements of the algorithms used in ArduPilot I am always on the look out for ways to improve the efficiency of the code.Unfortunately the standard Arduino…
"Jason,
The GPS decoding bug is as follows: GPS_UBLOX: in function decode_gps, case 6, the received byte should be added to UBX_buffer and included in the checksum BEFORE the test on the payload counter to decide whether we have received the full…"

"I've spotted a bug in the uBlox GPS decoding which means that corrupt messages are not rejected.
If you are happy to add me to the google code project committers then I will gladly submit a fix - which would be the easiest - if you don't want more…"

"VTI:SCP1000 - agreed the device package is not hobbiest friendly but there are a few versions of boards around with the device already soldered down. I've used one successfully with TWI (IIC) interface, but now find that VTI have quietly…"
"What does anyone recommend as a client for accessing the subversion repository of the source code, presumably there aren't any which integrate with Arduino IDE? I've got Visual Studio which I use as my main IDE for development."
"Have you ever had a GPS lock from your GPS module (presumably it is a uBlox 5)?
For a first fix try to have a good view of the sky and just be patient.
There is a utility "u-center" available from uBlox web site which you can run on a PC which I…"

"Changing the last variable to be UBX_ck_b I can now get a GPS lock indication - hence the line is now:
if((ck_a=UBX_ck_a)&&(ck_b=UBX_ck_b))
I hope this is useful - I'm still very new to this so appologies if this turns out to be rubbish."
if((ck_a=UBX_ck_a)&&(ck_b=UBX_ck_b))
I hope this is useful - I'm still very new to this so appologies if this turns out to be rubbish."
I'm not getting a GPS lock with uBlox 5.I wondered if the checksum comparison (below) is correct as UBX_ck_b is not checked but UBX_ck_a is used twice?Code extract from GPS_UBLOX tab:if((ck_a=UBX_ck_a)&&(ck_b=UBX_ck_a)) //Verify the received…
