Hy Jordi, Following your advise I ordered from SparkFun Electronics:
a) Header board for STM32 Cotex-M3
b) USB cable
c) Bread Board Power Suply USB 5V/3.3V
Please tell me where to order the remaining components (JTAG programmer/debugger, libraries, etc.)
A bientôt, Georges

Hi Constantinescu...
As I found out there are some issues with the code in the Arduino 0011 environment (it works for me in 0010) - i assemble my teststuff tonight and then will get back to you with my findings and my test pde which I am providing here.

Hi Christoph,
Millions of thanks for your answer. I read about your calibration stand. It is magnifique. I will try to make something similary. Please tell me which is the program necessary for reading a .pde file. Do you think that I must charge the 0010 version? A bientôt, Georges

Hi Christoph, I have got the code of chad working on arduino 010. Uff!! The same code on 011 does not work. The compilation bugs with a lot of errors. Please tell me the procedure for reproducing your magic program with the cube. A bientôt, Georges

My kalman filter is basically a copy of jordi's arducopter kalman filter code, so I'd recommend you start from that. I haven't really advanced much from his code in terms of attitude measurement, as I've been working on magnetic heading and barometric altitude.

Hello Alec, Thank you for the answer. I will try to do so. By the way, do you know about a Kalman Filter for 3 accelerations (biases) Ax, Ay, Az. A bientôt, Georges

Hi Constantinescu, pleased to read you. I'm sorry i did not introduce myself before the request. I'm also living in France (Nantes).

I have the same board I guess (STM32-H103). I plan first on getting used to the board: basically learn using uart (done), pwm (done), and adc. Then i would like to design a new board which integrates stm32, pwm outputs, accelerometers and gyroscopes in a small package.
