Hello,

is there anything similar to "simulavr" for use with Teensy/ ARM ?
I need some vcd outputs of my code to check timing in gtkwave.

thanks wally
 
I've heard of ARMulator but that's about it...

I'd personally use a picoscope connected to a physical GPIO pin. Logic analysers are also very good for this
 
What sort of quanta of time are you looking to measure here?
There may well be a software solution.

It's always good to get an actual reading with microcontrollers as they suffer from lots of things that can mess with timings such as prefetching, interrupts and 1/2 clock instructions

Signals to drive a linear ccd sensor
 
Xenoamor, (you live up to your name :)

Thank you for this offer, but I know Teensy for few days yet, so I'm much more busy
to familiarize with this little mighty thing. I have BusPirate and a other device from Saleae
to measure. Not very professional but sufficient for me, especially when I will get behind the secrets of sigrok.
What are you doing with the microcontroller stuff ?
 
I've heard good things about the BusPirate. I actually use either an FPGA or a Teensy to create stimuli but BusPirate is certainly on my 'to get' list.

I actually have a picoscope 2205MSO here and they provide a really rather nice free PC GUI to go with it. For the price I decided I'd rather that then get involved with Sigrok.

I'd love a Intronix LogicPort analyzer though. I've used one many times and lets just say. For a company that have only one product and have worked on it for ten years. It's very well polished and runs at 500Mhz

And do you mean what am I currently using microcontrollers for..?

I just wanted to see if we have some overlaping projects.
My most busy field of interest at the moment is spectroscopy, especially
HPLC with several detection methods, but making it for non-absurd pricing
available more or less opensource.

Does it work with Linux? Their download page looks like Windows only.

It does, but not natively as it uses the proprietary D2xx drivers.

You have to use Wine to run the application and use this as a go between for the windows -> linux drivers. It's a pain thinking about it actually, perhaps I'll write them a message and see if they have any intention to port it over. Probably not though. What a bummer!

I'd actually be very interested in HPLC as I spend a lot of time brewing beer. It'd be great to collect some real data on the beer's IBU (bitterness)

I currently work at a Electroluminescent and LED research company so most of my Teensy use is whipping up quick demonstration pieces. It's really a very ideal prototyping tool, I think we must have about 60 of them over here. Coming from a very solid Atmel background it's really helped me to get familiar with the ARM architecture.

For now I'm working on a fairly large FPGA project. We're hoping to have 200+ or so FPGAs communicating
 
While I cannot contribute to the main discussion topic I would like to express my interest in anything to with HPLC. I operate and Agilent 1100 HPLC unit with DAD detector and the current Agilent Chemstation software. This is used for identifying dyes, pigments and other aspects of museum collections and archaeological artifacts. I look forward to your future posts.

Really Steve? The Intronix LA1034 LogicPort one Xenoamor mentioned? Their download page seems to have only a single software link that's a .exe file, and 4 links for help files in different languages.

Yes, I'm familiar with Saleae. I bought one a few years ago. The Linux version is so buggy that it basically doesn't work. It frequently crashes, after acquiring data from the hardware, causing you to lose all your work. The version I downloaded back then was 1.1.15. I just looked at their site again, and they now have a 1.2.5 beta test, but the main download is still 1.1.15.

I talked with the Saleae folks at Maker Faire a couple years ago, about the terrible experience with their product. They seemed genuinely surprised, but after a little while they readily admitted they pretty much don't test the Linux version. Only the Windows version gets any significant quality testing.

In my mind, there's a big different between "work with Linux" and "hand a Linux version of the software". If the software is so unstable, crashes so frequently causing total data loss, it really can't be said to "work" in any meaningful sense.

I believe he was referring to the Saleae

Yep very much. It's really a pain when programmers often work on linux and want their test equipment to run on the same environment. Even the picoscope 2205MSO, which is a 16 port logic analyser, amongst other things, still suffers from the odd crash on linux.
Not surprising though, gauging from their forum responses to reported bugs usually consist of "Does it happen on windows?"

I don't have an Intronix.

Saleae has improved a lot.
I use it in windows and it is quite stable and it's better for me than the logic analyzer in the Rigol 'scope.
The Saelea has a lot of built-in serial decoders, free whereas Rigol and others try to charge for every little add-on.
I've read that the Linux and Mac versions have happy users now, with the newer firmware.

But yes, economics drives engineering tool sellers too.

And PJRC's testing rigor on Linux.

I like Linux. But, well, software sellers have to make a living!
