Just a guess...

The program that will coralate all the data has not been released!

I don't know what the first piece of data represents. It increases with each card write. Anyone know?

Jerry....

Timestamp or cycle count?

Yes, first field is milliseconds since the unit powered on. If you are getting stuttering on the lights then your sd card is probably not fast enough. Stick with the good brands like Lexar and SanDisk. They implement the sd card specs properly. There may be other good brands too. Surf the net for the best sd cards for write speed, that's what matters. The SanDisk I have writes the data to disk in 12milliseconds worst case - and the write occurs every 5 secs like you say. 12ms is way to small to notice.

look at this!
this a a U-blox,I think!

Quadrino GPS Position Hold (5 min 53 sec)

I'm new to quads, I just finished my 650 next level quad with quadrino zoom v2 with 2.1 firmware. I had a successful hover but I need help setting the PID rates and I need help with the sensors. First, How do you change the PID rates, do you change them in the config. program or somewhere else, also can you have different rates for different switch positions. Finally what sensor should I have on in any given switch position. I do have the sensors on a three position switch.

Anyone needing help!
Webex is open now and will be open for about a hour starting now!

Password is always "quad"

Go to flyingeinstein.webex.com

The SD card I got is a 4g SanDisk. I remembered that this was discussed on the webex last sunday and SanDisk and Lexar were mentioned as fast units. I'll make a small video tomorrow showing the light sequence when it's writing...

MultiWii dev version r1311 has lot of feature updated.:
- baro Alt from mahowik (new functions to come, noted)
- baro calibration and some baro mods from Sebbi
- new task scheduler for a better computation time repartition
- better Ublox code detection
- HORIZON mode (mix between ACRO & ANGLE)
- ANGLE mode is the old LEVEL mode
- every UART for everything on MEGA
- cool GUI enhancement from magnetron
- spektrum bind button for spektrum receiver (Danal)
- telemetry cosmetic
- bug correction for servos on MEGA
- failsafe is more robust

- variometer
- mag gain calibration improvement for HMC5883L
- GPS MKT binary parser
- GPS forward predictive filter

blue light still doesn't work?

haha, me too! This one i like most:
Assisted AcroTrainer **********
/* Train Acro with auto recovery. Value set the point where ANGLE_MODE takes over.
Remember to activate ANGLE_MODE first!...
A Value on 200 will give a very distinct transfer */
#define ACROTRAINER_MODE 200 //

"Amazing to watch a quad come tumbling down with minimum throttle, and then level itself automatically, just before hitting the ground"


Bledi has a video on Acrotrainer:

Use this and feel lilke Warthox for a while.
