MUX v 16 problem

I made a similar mod on Razor board - removed capacitors for HP filter but left resistors in place (at least for now....). Green arrows point to bridged connections where HP caps used to be, and blue is my 'Boo-Boo' - by accident removed cap for P...
Just added these instructions to the manual as well...
Oops.. Corrected thanks!
"Not all the ArduIMU's flats have low pass filters, please double check." I think you mean "high pass filters"....
The next version of ardupilot will have SAT's information available... ;-)
Some details you must remember:
-Your solder skills must be advance or medium-advance to attempt this.
-If you try to do it with your razor remember that you will void your warranty with SparkFun.
-The same with ArduIMU, if you can't do it i will...
Hello Assembly pictures of the new shield are located here.
Chris, Yes I changed this for the v2/blue shield.

How to remove the High Pass Filter from your ArduIMU and Razor boards.
Some details you must remember:
-Your solder skills must be advance or medium-advance to attempt this.
-If you try to do it with your razor remember that you will void your warranty with SparkFun.
-The same with ArduIMU, if you can't do it i will for you (free of charge).
-Not all the ArduIMU's flats have high pass filters, please double check. Check if the HP resistors are already gone.
To remove the capacitors and the resistors is pretty easy. First try to set the highest temp possible in yo… Continue

More news.. (Including new 2Ch OptoCoupler and ArduIMU Flat issue)
For some reason my left index finger hurts me, so i can't type very well. ;-)
I'm setting up ArduIMU and ArduPilot SVN repertory, in conjunction with Google code. In that way you will be able to track all the changes made to the code and spot the differences between revisions with the possibility to comment (or complain) about it.
Lets do an interesting example, if you go to google code repertory for ardupilot and you click in the tab "source" and then in the option "Changes", or just click he… Continue

Can somebody tell me the meaning of this picture?
The first two in guess it correctly, will receive a unit free of charge including UPS shipping. Limited to one international.

The Best Stabilizer!
LOL, i was wondering the refresh rate of that thing:

Constantinescu said… - Congratulations for your anniversary. I will try the explanations ASAP when I will be back home. Which is the best ADC, after you, to use with IMU 5DOF I bought? Jason Wood used an MCP 3208 but:
a) his associated kalman is only for the angle and the gyro_bias, not enough for such a sensor;
b) he uses an ADC not so strong for IMU 5DOF (only 12 bit)
c) he uses some library functions at which I can't have access.
d) dreaming to use something like ahrs.c we discover the memory limitation
Saturday morning I will go a week for a short trip in Madrid. Maybe the very beautiful and very catholic Espagne will help to find a solution.
A bientôt,
Georges

- But he is using it for an helicopter?? Yes i saw some projects using the same sparkfun board but they used it in airplanes (and 12 bits ADC), no helicopters, and the system work at 3 volts so the voltage reference is excellent for this IMU, arduino uses 5 volts and the ADC reference is between 0v to 5v, no 0v to 3volts (remeber that the 5DOF uses 3 volts)... Well i obtained a good ADC with 16 bit resolution... an works with I2C... butt i don't know, could work if you only have one or two sensors... but five is too much, i2c is a easy to use port, but is slowly...
Ah maybe the problem with your library's that you cant just copy and paste the code, you need to adapt it to arduino enviroment
Well you can try... but i will give you an advise try to void using arduino for helicopters (maybe for airplane is feasible) but for helicopter you need high refresh rate to maintain it stabilized..
Ok just because i like you i will tell you this:
I recommend you this microcontroller:
http://www.sparkfun.com/commerce/product_info.php?products_id=8559
I can give you the link to download the Keil Uvision for program ARM in C++, and where to buy the JTAG (ULINK2) to program it... This MCU works with 3 volts, ultra low power, you have 3 UART ports (serials), 12 bits ADCs, two I2c, and is 2 dmips of power, that means more or less than 200 arduinos attached together of processing power, and consume the same energy as only one. IS based in the ARM Cortex M3, you know ARM right??? is the microprocessor of all the cellular phones (even iphone), and PS3, etc. etc.
I using it to program my next airplane autopilot and i don't have to worry about power any more and ports.. But you need to read a little bit... and expend some time to get the ARM... but at the END is very easy.. even easier than arduino..

- Hy Jordi, I am back from Madrid. It was wonderful (Zurbaran, Goya, El Greco, Picasso, etc). What about JTAG (ULINK2) source you promised me? I tried to look on the net but the price of this equipment is big. I found a quotation around 350 dollars. Please send me your opinion. Mean time the sparkfun send me the Cortex M3.
A bientôt, Georges

Work as the ulink2 but is called ulinkme (check it in keil webpage). I used it and is very good.. (was include with my development boards). I also recommend you buy the keil ST32 develiment board because includes the ulinkme free... =)

- Hy Jordi, I found very easy the first reference but for the second I am not able to choose one. There are many options and as I am not sure I prefer to ask again your help. Please send me the pointer for the product as for the first one. A bientôt, Georges

Túlio Fernandes said… - Hi Jordi,
I saw that photo of you and another guy holding an white aircraft, could you please tell me where did you got one of those and how much did it cost?
I'm from Brazil and I never saw those models around here, maybe I will have to buy one outside to use in my grad paper.
Thank you.

Have a great week man!
