"Decided to convert all the I/O between the Robard and the APM (and a VectorNav device I am also trying out) from I2C over to USB. Bad idea. It was a long process and I learned more about USB than I ever wanted to know. Roboard was using almost 100%…"
"Chris, I'd be interested in your experience with the Gress Aero platform. Any progress? I just got an nVader. Haven't done much with it yet, but hope to implement an IMU based attitude stabilization for it."
"It's amazing how far Arduino has gotten without a debugger. But no it's not just you. I feel like developing code without a debugger is like typing with your nose. It's not impossible, but it's a really inefficient way to go."
"The review quotes 30 minutes battery life outdoors and 45 minutes indoors. I have 2 of them, and 10 minutes is a lot closer, maybe 15 at best. But they're still a blast, surprisingly rugged, and uncannily stable. I took one to work and flew all…"
"Got RoBoard and APM talking @400kbps on I2C. Need to provide level translation from APM 5V to RB 3.3V levels. Could have used an external level translator, but cut 2 of runs and added 2 jumpers to APM IMU Shield board to connect the IMU's on-board…"
"Yes I agree. Windows is not a good choice for a real-time OS. But it is good for s/w development with Visual Studio and remote debugging. I'm trying it for now, but keeping the option open of re-porting the code to a more appropriate OS when the…"
"I removed the display adapter after getting XP loaded. Now I connect via Remote Desktop over ethernet. Perhaps it is possible, but I am not aware of a way to load Windows without a display controller."
"1) Yes, you use a micro SD card for the "hard disk."
2) You will need the VGA card just to load Windows. It may be possible to load the OS without it in the case of Linux, DOS, or other OS, but my experience is only with Windows.
3) I'm coding in…"
"A few more notes/comments/responses:
The RoBoard is running at < 500ma (without the display adaptor). I removed the display adapter after getting XP loaded. Now I connect via Remote Desktop over ethernet.
I must admit, it's an order of magnitude…"
I've been getting the RoBoard up and running because I'd like to have a lot more compute power than the Arduino platform has. My plan is to interface RoBoard to APM, use APM for most of the I/O and eventually do some higher level vision processing…
"I set up a pitot on my T-28 Trojan and logged GPS and raw pitot A/D values on my APM setup. Subtract off zero level, apply smoothing, take square root, multiply by 1.45. After accounting for light wind, quite good agreement with GPS speed above…"
