"Hi PixHawk,
Thanks for the reply.
I hadn't considered all of the communication decoding.
I think I saw someone from your group post to the ROS mailing list regarding LCM:

ian commented on Chris Anderson's blog post Introduction to PixHawk ground control station (including source code)"I'm curious of other's opinion, or if the PixHawk developers have time to respond:
-it seems most of the current implementation could easily be reproduced in HTML/5, the exception being the graphing component, since aside from flot and a…"
ian commented on Reto's blog post Xbee socket board"Thanks for the comments Jordi. Since I already have 3.3V levels on my uC though, I was mainly curious about assembly differences. Given the negative comments on the sparkfun site regarding assembly: did you find the adafruit pcb to be less…"
ian commented on Reto's blog post Xbee socket board"jordi: Can you say what you do not like about them? I have neither, but since my uC is already at 3.3V (not an arduino), I don't need the level converter on the Adafruit board, I guess the the leds might be helpful though. On the Sparkfun site…"

ian replied to Adam Carter's discussion HD Video"The elphel camera is open source, cheaper than the Axis stuff, has several compression schemes, can stream via WiFi to an open web client they provide, and is capable of capturing 30fps at 1920x1088. Up to 8 SD cards can be used for offline storage…"

Math models for inertial navigation and selection of a microcontroller
Posted on January 12, 2009 at 11:06am 4 Comments 0 Likes
I am trying to decide on a platform, but I would like to consider the math model being used, an the whether there is a need for floating point on the microcontroller.
There are several models available for inertial measurements - some handling drop out of the GPS signal better than others, etc.. I'm trying to decide on a platform to control a multi rotor craft - quad or something similar to Jack's latest iteration using five propellers - but I'd like to have the option (if possible) to… Continue
