Ratio Computers loves your work!
Dear Subsurface developers, I'd like, first of all, to express my personal and my company appreciation for the great job you've done up to now to support our dive computers. Since January I've been hired at Ratio Computers as their new CoE and I like so much your work I'd love to see our dive computers completely supported. We would love to tell our customers the application we sponsor for PC interface is Subsurface instead of our current, and outdated, Divelogger 4 application (running only for Windows and Mac). Nevertheless up to now Divelogger is the only application allowing to update our dive computers firmware, a thing we would love to see in Subsurface too. Unfortunately, due basically to lack of free time, I cannot add that feature to your code by myself: I need someone who would like to do that. So don't hesitate to let me know if there around someone is willing to implement additional features to support all the Ratio Computers features. I'll share with him/her all the information he/she needs. Again thank you for your hard work, R. P.S. I've not seen any way to sponsor the Subsurface Project with donations... haven't you thought about it? -- Riccardo Brama, Ph.D. Chief of Engineering Ratio-Computers, a Dive Industries s.r.l. brand Via Vetturini 22/24 58024 Massa Marittima (GR) Italia Web: www.ratio-computers.com E-mail: riccard...@ratio-computers.com Ai sensi del "Testo Unico sulla Privacy D.

Re: Ratio Computers loves your work!
Dear Dirk, it seems to me you felt my email as something aiming to harm either your work or your freedom. I'm sorry for that and be sure I was not meaning anything like that. What's true is exactly the opposite: we would love to contribute in some way in it, providing documentation, specification, information and our support. Since my time is limited I thought that writing in this ML could have helped me in finding someone who: 1. Knows the project well; 2. Is willing to work on it implementing some new features improving the support for our dive computers; 3. Is available to collaborate with us on such themes. I know open source projects are usually lead and/or developed by people yet having a well paid job, but maybe, out there, someone is interested in a position taking care of developing such enhancements with us. >> We love seeing involvement from the dive computer manufacturer, it tends to >> make many things easier for us too. > No doubt that is true. That was our aim: making things easier and giving people something they love. > So: I have no problem with someone else using Subsurface for whatever > purpose they want (as long as they comply with the license of > Subsurface and the components that we use - i.e. make the full source > code of the version that you ship available to any user, among other > things). But I politely request that you change the branding and that > you provide your own support. You can call it "Ratio-Divelog (based on > Subsurface)" or just "Ratio-Divelog". But please don't call the thing > that you ship "Subsurface". And please don't point your customers to > us for support. I never thought to point our customers to you for support, be sure. Anyway, got that: if you prefer we can start a spin-off of Subsurface for our customer's needs. > So yeah, this is where Linus and I disagree. You want firmware update > support? Go ahead, implement it, publish the sources (see above about > the license requirements), and we'll decide if we want to include > this. But no, we won't do this for you. Ok, sorry for having suggested that. I thought it could have been easier to find out some skilled people within the Subsurface developers community instead of starting things ground up. Nevertheless I will try to see how we can act to do that. Again, sorry if you felt my email was aiming at limiting your development freedom: that was definitely out of my scope. Hoping to hear us soon for news, My very best regards, R. -- Riccardo Brama, Ph.D. Chief of Engineering Ratio-Computers, a Dive Industries s.r.l. brand Via Vetturini 22/24 58024 Massa Marittima (GR) Italia Web: www.ratio-computers.com E-mail: riccard...@ratio-computers.com Ai sensi del "Testo Unico sulla Privacy D.

Re: CNS calculation headaches
Robert, I totally agree with you on the use of a two functions interpolation. One to be used up to 1.5 the other one (that seems to me to be well approximated by a linear interpolation) for higher values. That would lead to less "underestimation" and to a behavior that seems to be more realistic. Cheers, R. Inviato da iPhone di Eng.

Dirk,
yes all of them share the same cable controller. It should work that way.
Thank you and cheers,

Re: Ratio ix3m Pro on Android
Dirk, I can ensure you Ratio cable is based on a FTDI FT230X USB to UART converter. Best regards, R.-.
