Project development, ideas, and suggestions / Re: Fabio Varesano & FreeIMU
Tonight I'm going to the Fabio Varesano Foundation to talk about this.
We need to create a new collaborative platform  for development, but I fear that this activity will take some time.
Do not miss your Patch, ...... you uses this time to write other patches and support FreeIMU ..... when we are ready everything will be added to FreeIMU.

thanks

[quote author="tyftyftyf"]Hello,

Does anyone know how to submit patches to the FreeIMU library? I saw a "TODO List" on the FreeIMU development forum and found some ideas there very interesting. I already implemented one of them, "Sensor Fusion Algorithm Cold Start", but cannot reply to that thread anymore (since there is no one to verify my account). How do I participate in the development of FreeIMU?

Project development, ideas, and suggestions / Re: Fabio Varesano & FreeIMU
I have heard that the Fablab of Turin has set up a foundation in memory of Fabio.
Some old friends have contacted the family and obtained the entire copy of your data and you are organizing to promote and continue its projects.
I know they're working on the new version of Fabio FreeIMU on which he worked and they are producing a number of modules.

I do not know the details and lostatus of this initiative .... but as soon as I know something more I will inform you.

bye

Project development, ideas, and suggestions / Re: Fabio Varesano & FreeIMU
I fully agree!

Perhaps I was a bit hasty in proposing hardware changes. I'm also thinking that the Software sincere worked perfectly. Apparently this is not true ....... it needs to be improved.

PCBs have available could be a start for those who know how to assemble the components above. I am not able :-(

Have the opportunity to purchase a fully assembled FreeIMU allow me to start studying it. Then in time we could talk about Evolutions Hardware if we feel the need.

IAN: It 'assessable propose Seedstudio to produce some examples of FreeIMU as it is? I am not able to solder the components above and would prefer a professional pre-printed form (as Seedstudio).

You are perfectly right but I and many other DP members do not have a FreeIMU for development. Unfortunately I could not find an online vendor.  You know a supplier?
DP is able to find the sensor needed to create prototypes of FreeIMU and print (seedstudio?) If you can take this route, I am willing to buy one or two modules freeIMU and work on the software.
You will need to create a new repository for development.
However, I believe that all decisions (or recommendations) on the development of hardware and software and management are working for Ian.
Who is interested in this project? PaulStoffregen you are interested in software development? Those interested Hardware Development?

Which sensors we can use? Any idea? I like chip digital interface (SPI, I2C, etc.) but do not know how fast they work.

A good design should guarantee at least 50 measurements per second. You agree?

FreeIMU sensor consists of the following:

MPU6050            (U301) ----> Gyro + Accelerometer
HMC5883L          (U401) ----> Three-Axis Digital Compass
MS5611 - 01BA03 (U201) ----> Barometric Pressure Sensor

What do you think? They are good chip?

I was thinking of adding an MCU to read continuously and quickly provide sensors and external data read (ISP? I2C? Serial?)

Hi,
I heard about this sad event a few days after Christmas in Italian mailing list that I follow.
I was told that Fabio has handled the entire project FreeIMU alone, so he did not actually worked with anyone else. Of course I cannot be 100% sure about this information.
FreeIMU consists of only a few sensors, does not have microcontrollers and it is released in Open Hardware and Software.
Ian, it is reasonable to think that we can start to improve this project.
We can decide whether to continue calling it FreeIMU or OpenIMU etc. but to pay respect to Fabio I think we have to keep track of the initial project.
Some ideas to improve a similar project? I propose to insert a microcontroller and a temperature sensor.

Hi Ian

I'd like to work around FreeIMU not be forgotten or lost in the chaos of the Web. For this reason, I wonder if you could take this project forward in sauce DP. 
From this project we could improve it because I think it is a very useful project in different sectors such as automotive, model helicopters, airplanes and quadcopters ..... etc..
We may also find areas of study and research. These types of modules are suitable for different uses.



Greetings

Project development, ideas, and suggestions / Datalogger
Hello

I am interested in a data logger that can be used on linux.
For years, I take care of the experimental model and I need to acquire signals from load cells to measure the power provided by the aircraft engines, triaxial accelerations, temperature and pressure so I need the analog and digital channels.
In the market I could not find anything cheap enough that you could use Linux!

We list some basic specifications
--------------------------------------
Analog Channels> = 8 Single (4 differntial)
Digital Channels> = 8 Single (including counter / timer)
Full Scale Voltage + - ... VFS programmable
Resolution> = 10 bit
Sample Rate> = 1000 samples per second
Interface USB (capture  Configuration)
SD card (acquisition  Configuration)
......

You can open a new project?

greetings

Open Bench Logic Sniffer / Re: fw_update.exe for Linux
Hello

[quote author="ian"]
I believe someone has made a linux version. You can compile it from the latest source in SVN.

What is the link to the SVN repository?

Thanks

Open Bench Logic Sniffer / fw_update.exe for Linux
I would like some information about the process of updating the Open Bench Logic Sniffer.
Two days ago I used the update process included in the package OpenBenchLogicSniffer-2.12-Setup.exe .... This is perfect for Windows users ......
Unfortunately I was not always at my disposal a Windows-based computer ..... is difficult for me to update the PIC firmware
It is planned to develop fw_update.exe for Linux (Ubuntu)?  The timing of the ninth release notes?


Thanks
Drake
