Serial via another Arduino with XBee
In case anyone is interested... I have written a small protocol dumper and serial passthrough for Multiwii. I put an Arduino on the aircraft with an Xbee, connected to the second serial port of the MultiWii. I then run the GUI into a USB explorer with another XBee on it. This gives me in the air tun...

Re: Fuzzy tuning of PID gains
Auto tune/assist tune from the GUI shouldn't be hard... start at a PID = 0, then increase P in steps, say every 10 seconds. The user can decide when oscillations set in, then fix P, then move onto I, etc. This would work for any board 8 or 32 bit. ANyone think this is worthwhile/useful?

Re: Attemp to integrate sonar (ultrasonic sensor)
I have a 32u4 based MicroWii (Hextronik) and a SRF-04. Is it possible to get Alt-hold to use this sensor directly from the MicroWii?
I have experience in coding the Arduino Leonardo, so can do some coding if that necessary.
Any suggestions would be appreciated...

Re: Spektrum Telemetry Feed
Yes, as have I... but I have this equipment lying around, so would rather use it than discard it. And the code is there and working, so why not? Also, its a bit satisfying to have reverse engineered the 'x-bus' protocol, despite Sputum's best efforts to obfuscate it! Why not offer a lower cost path ...

Re: Spektrum Telemetry Feed
Hi all, I have a Dx7s and TM1000 and SPektrum GPS. I have written code for my home brewed FC which reads the GPS data via the Leonardo's I2C (yes, x-bus is just Sputum-proprietary-speak for I2C). The GPS module is a slave, the Leonardo must be the master. This means the I2C pins are used. The GPS mo...

Re: Fuzzy tuning of PID gains
How about doing the auto tuning in the Processing GUI app? No RAM/code size issues... I am using an XBee 2.4GHz to get in-flight access via the GUI (and others are using bluetooth) so all the interface needs is a button next to each PID set saying 'Auto tune'. Additional features could be starting l...

Re: Hexcopter/quadcopter losing throttle power after awhile
I had a similar problem after I mis-connected some of the connections to the rx. It would not develop enough power in any mode to lift off. Checked everything, couldn't get it to work. Found this thread, cleared EEPROM, recalibrated ESCs, reloaded MultiWii, recalibrated accel and mag, and viola, it ...
