Yes. Though I haven't tried it, it should. There are a couple of points on the circuit board where you can stick a link.

I tried this out today. Great code Neil and Sugarbear's package worked well.

My results are below.



Interestingly I could not get the throttle opening above 89 degrees. I understand that the butterfly valve only actually opens to 82 degrees but that widgets can overread?

My only concern is whether my throttle is opening fully or not. What should startrek be showing on a properly working normal throttle?

89 degrees is fine. It's differential, not absolute.

To be honest, you won't even notice a degree or probably even ten at the top end.

Thanks neil.

Is there any way to "graph" the outputs from Startrek - i.e. something that monitors the inputs whilst driving and is capable of then importing those values into a table so that the results can be seen over a period of time?

Not for the 20v version, I'm afraid.

Of course, the source is open and it wouldn't be difficult to implement... be my guest!

It's beyond my IT ability I'm afraid otherwise I would do it.

Such is life. Good bit of software for the money. Would be particularly useful if ever the car would not start etc.

I'm sure you could just take the outputs (which are displayed to screen), into a text file, formatted for excel or similar.

The only issue I thought was the speed at which main loop is iterating at, did you say Neil somewhere that the speed is important to avoid the comms being dropped?

I can't remember whether that was the error codes (as off the top of my head, you only go into that section of code once for every 10 iterations of interrogating the sensors) or would be ok to write to a text file within the main (Sensors only, Battery Voltage etc) loop?

The main loop gathers all the data in one chunk, then decodes it and writes it to the screen. I'd probably open a text file (call it *.csv to simplify displaying it in excel) and just repeat the screen write - which takes a short string - to the file, with commas between values and a carriage return at the end of the line.

A modern computer won't have a problem keeping up with the ECU.

Does anybody know if Flash can take inputs / values from COM port or something?

It would need to be able to set the port parameters, too, and handle the input and output on a byte-by-byte basis.

FYI regarding logging data. When getting a remote "live mapping" this summer I needed to provide Startrek data, so I took an old briefcase and strapped the pc and a video camera on it. Then the video camera recorded the pc screen with the startrek output.
Finally I send the recording as an avi file to Flea.
This way I could keep my eyes on the road and had the recording for later analyses.

That's one way, I guess! Googling 'record pc screen' returns loads of hits; I'm sure some of them must work - that might be easier.

Haha McFall that's one way of doing it I suppose...

Alternatively, have a look here

And choose from many free programs which will record your PC/Laptop screen. Much easier..

Is it possible to get this style of display of dials output from the widget on a 20VT or is it an additional something that needs downloaded from somewhere (if it's available)?

It's some experimental code I wrote for a future version of startrek, but I never finished it. It's designed to take a huge number of Fiat group ECUs of Coupe vintage, but was largely experimental. The large number of graphics calls made it a little slow on the laptop I used at the time; I haven't tried it recently.

It wouldn't be too much effort for some (other) programmer to graft the styles onto the original startrek, but it's not something I have time for at the moment - too many other things on!

Flash didn't have native COM port access last time I checked, but you can compile with zinc (and use the zinc libraries) to add COM port access to flash.

I've used it before to talk to a modified barnacle design (cheers Neil) and it worked fine.

just found this on the forum.. can anybody tell me were i can get a cable and software

http://www.nailed-barnacle.co.uk/coupe/startrek/startrek.html

Sugerbear may have cables available.

Ok guys, got my laptop back and i'm dying to work out how to download the barnacle star trek software from his website...

Anyone who has previously done this, could you explain in A B C to me please... Thanks muchos

Roger

why do i have to have a macbook

Because for everything else it makes sense

lol.... very true. but it seems a lot of work to set up boot camp or parallels just to use star trek. however i'd save a fortune in diagnostics bills!!

what do i actually need to run startrek on my mac? ie cable wise? i can do all the bootcamp stuff myself...

pleaseeee help.... download instructions for novice lol


i have a 20vt
windows XP software
and no idea what i'm doing


... i may need to stick with my own trusty mechanic diagnostic skills if all else fails aha

thanks guys.

I haven't had any experience with the mac, but it seems that Wine is available for it: http://davidbaumgold.com/tutorials/wine-mac/

You're on your own there; but I run startrek under linux/Wine with the USB port mapped to com1, with no issues. I believe you can probably do the same on the mac; if that's the case perhaps you'd be kind enough to do a how-to on the subject so others can benefit. There are other mac users on here who may be able to advise.

If you do it on the mac you almost certainly won't need to install the FTDI drivers; they're probably native to the mac already.

Razor, you need to download the software from my site - http://www.nailed-barnacle.co.uk/coupe/startrek/startrek.html - and read the page! Everything you need should be on there, but don't forget you'll need to install the drivers for the USB adaptor. I've put a link on the page, but make sure you read the installation instructions on the FTDI page!

Thanks Neil
I'll give it another go tonight.

the ftdi driver are they the vcp drivers that are needed?

Yep. Though for windows XP and later, there's only one driver, does all functions.

If you're using Linux and Wine, you don't need any drivers; they're in the kernel.

Qucik one,the exe is named below and my port is com 8

startrek_bosch_M2_10_4

What do i write in the command prompt for it to start reading

ive tried
startrek_bosch_M2_10_4 com8

And states unable to open com port.

Thankyou

Should i replace the _4 with 8?
