    Re: CErase, Cwrite problem

    Seconded.

    Also Tim,
    When you say "higher up" or "high" in memory, are you referring to > 0x1000 per se? As in towards the higher addresses?
    Because I was following this thread and getting...

    Re: CErase, Cwrite problem

    What?

    The bootloader I've been tweaking, and changing, although it works fine, uses these routines without issue.
    What's wrong with making use of these functions, compile the bootloader code,...

    Re: Huge explosion at Japan Nuke plant.

    I was unaware of those details Joe. I had assumed, wrongly, that a lack of available power backup system was due to there being no batteries, and failed generators.

    To get somewhat off topic, for...

    Re: Huge explosion at Japan Nuke plant.

    I have to agree with you that the primary cause of this was a lack of a backup power supply system other than a diesel generator. It's kind of silly when you think about this, every data center that...

    I'm currently working on documentation and final commenting of involved code to be released.
    I'll post an additional update here when content has been added.

    Re: PSTN Dial Tone emulator

    Maybe you could use an el cheapo VOIP bridge ala MagicJack or the like?
    They can be picked up in the US for about $30. I've used these for testing other equipment and it worked fine.

    I've thrown up a front page for now that serves as an overview to the project.

    I'd be very surprised if this was ever implemented in Proton, I'm pretty sure I saw this discussed by Les in another thread when I was searching for a method to use local variables.

  19. Re: Can I get the "version value" of my source code?

    The version information you see is strictly related to the IDE. It is not compiled anywhere in your code. However, you could write a plugin for Proton that would hook the pre-compile message and you...
  20. Re: Editing posts in "Code Examples and Projects - Moderated"

    I agree with you 100%, of course nothing will ever stop it. Some manufacturers prefer security by obscurity, which really isn't security at all. The best locks are still difficult to pick, even when...

    Ah, yes, decapsulation and such. I'm aware of these physical attacks.
    There are tricks to making this much much more expensive to pull off. For instance:
    After writing the bootloader you fry PGD,...

    It's useful for a bootloader. So firmware updates can be delivered encrypted.

    Specifically I'm about to release a secure encryption algorithm written entirely in Proton.
    I'll take a look at the Wiki site now.
