I had to use a gui app to unshrink that sucker on the mac! :-/
What are the channels?
Did you get the CAN decode to work? Which speed?
Did you know that you can change the labels in the logicdata file and save with that?
Did you know that you can add the decoders/analysers to channels and save with that?
I'll be following your progress on this :-)

That's really funny, because I've been looking at getting a really cheap trailer to live in to get out of paying rent. The really cheap ones are about a months rent. The kind that's even too trashy for a trailer park so you camouflage it in the woods or bury it in an old flash flood ravine in the desert. So that the nice government men don't harass you about it being an illegal structure, or not moving 100ft every 21 days.Fred wrote:I'm happy to help accelerate you along your chosen path to alcoholism and a trailer-park life
Awesome, although it seems to have lost my Saleae settings from Ubuntu to windows. :-/ So I switched to 7z.Fred wrote:Fixed!
Same as the wire colors except for the one green wire which is on the Blue port. 0,4,5, and 6 if I remember correctly. 5 is the interesting one.Fred wrote:What are the channels?
On 5 I found widths around 3.75-4.25uS, so 1/0.000004 gives a bit rate of 250000. Which means I need to move my sampling frequency from 16MHz to around 250kHz to get rid of the 62.5nS wide pulses, noise I'm assuming.Fred wrote:Did you get the CAN decode to work? Which speed?

LOL
If bit rate = 250k then you should sample at least 500k to capture them. You might need more if the pws are fussy.On 5 I found widths around 3.75-4.25uS, so 1/0.000004 gives a bit rate of 250000.

Just opened your new file, cool to see it decoded like that :-) Have you made any sense of it yet?

Ya, I got the megaupload reference, I took the statement more as use one of many file hosting sites.Fred wrote:It was a joke!
Not really. I talked to mike about it a little bit. I exported the data to a csv text file, and then wrote a small program that opens it, and reformats it without the Saleae data logging stuff. So now I need to filter the text file for good commands, and remove all the duplicate commands. Then program the TA card to send the commands over the CAN interface.Fred wrote:Have you made any sense of it yet?
I ordered a turbo that is suppose to be here tomorrow. When it shows up I'll have a turbo that I can take the housing off of, and throw commands at to see what happens.
:-p

You forgot this one.

$1800
I think these controllers are all way too expensive. What do you guys think a fair price is for a programmable controller without a display?

Re: Holset HE351VE VGT Turbo (NO 56K)
That depends on the volume of production, the existing knowledge, code and PCB work that could be leveraged, and the amount of R&D time stuffed into it.Peter wrote:I think these controllers are all way too expensive.

Volume has to be low for this.
R&D time is proving to be fairly high.
Most people would be starting from scratch.
Then you have to look at the "is it worth it" factor, from the customers' point of view. If priced too high, none will sell, even if you're effectively losing cash on each one (due to your hourly rate and R&D time).
That's why it's admirable of you to be working on this for the good of all, as the cost to you is measurably high, and the return on that investment almost certainly only love and respect. Excuse the hippy, but you're making the world a better place. Excuse the realist, at great cost of your hours/time/life.

Re: Holset HE351VE VGT Turbo (NO 56K)
So if I ever get this working correctly, and up to Fred's standards. I'm thinking that they should be cheap enough to build that I could offer 20 or so of them for free in exchange for youtube videos of people smashing the shit out of their over priced controllers.
