Other Equipment & Products / Re: FTDI driver kills fake FTDI FT232??
« Last post by maxstone on Today at 06:51:30 PM »

This isn't "FTDI's driver accidentally damages clones". FTDI's driver contains code blatantly, explicitly, and clearly designed to damage clones.

They removed their vendor ID from clone chips, nothing more.

Microcontrollers & FPGA's / Re: delay argument too long
« Last post by Torrentula on Today at 06:46:22 PM »
I'll bite. The simple workaround would be:

Code: [Select]
void _delay_100ms(int n)
{
    while(n--)
    {
        _delay_ms(100);
    }
}

int main(void)
{
    // 1000 ms delay
    _delay_100ms(10);
}

Should Vishay be able to remotely brick your MacBook air if it contains a counterfeit resistor?

Why not? Although inconvenience, I would just get a refund from Apple. Who in that case would be in the wrong, not Vishay.

Suuuuure.

It's guaranteed by trading standards in the UK.

should you scream bloody murder if they _try_ to give you that free service, but fill oil pan with brake fluid due to differences between real and fake one?

You sure as hell should scream bloody murder if they go ahead and punch a hole in the oil pan.

Not sure about why I would buy a Saleae when I already have a Logicport? Are they better in some way?


That's true. I have not used the Logicport so I can not give you any comparisons.

The Saleae is a toy compared to the Logicport. Just download the free Logicport Software from www.intronix.com (the demo mode will act as if the hardware would be connected) and and compare it to the Saleae stuff.

Projects, Designs, and Technical Stuff / Re: IC powered via non-vcc pin?!
« Last post by Gizmo on Today at 06:43:29 PM »
It's definitely off. 0v registered on the reg output until I enable the address bus, then magically the 5v applied to the output leg seems to power everything up! I am happy with the explanation given above as to what is happening. I am going to move to using 2x 8bit tristate binary counters linked together as I can't find any larger counters with a chip enable / output enable.

An interesting one to learn anyway! This stuff is all quite new to me so I've got a lot to learn... :)

Which Microsoft et. el. do all the time if they detect a fake serial (or Vendor ID in FTDI case.)

Do they?

I'm guessing that you can yoll back the driver and use the FTDI util to change the vendor ID.

Test Equipment / Re: Agilent U1253A - dim display lighting
« Last post by toli on Today at 06:39:58 PM »
Thank you for that. I've looked up on Google and didn't run across this discussion.
I was actually surprised by that, I though those issues are a thing of the past with the silicon they use for OLED display nowadays. I can understand it happening on older technology where the device characteristics would shift with the continuous current through it, but I didn't realize it will happen on this display. Especially given the fact it was only lightly used and was always kept at the low setting for the display.

So reading that thread, and the one linked within it, I see there's basically nothing to do except for throwing it out or hoping Agilent will be willing to offer a replacement with an LCD screen for a reasonable price?  :wtf:

Open Source Hardware / Re: OpenLab Standard
« Last post by awallin on Today at 06:29:44 PM »
There already is an instrument standard. IVI.

http://ivifoundation.org/resources/default.aspx

...

If I was writing yet another device driver (oh it can be painful) and it was for open sourceable stuff, I would join IVI and make it translate to that standard for sure. $700 US per year. http://ivifoundation.org/resources/default.aspx


what about LXI over ethernet. Are there licensing fees for that too?
Someone needs to write a simple C/C++ library that is portable to all the MCUs people are using and uses standard Ethernet with IVI/LXI/some-standard for communication - that would be a step forward IMO. It needs to be a standard where the library-writer, developer, and user are not required to pay licensing fees or where the standards-document costs money to read.
