I've used it and it sends packet like stuff that seems to not work. The red button breaks some of my code instead of resetting. Not sure if its your fault or mine, but we'll know very soon :-)

The big red button is UBER cool though :-)

I'll see what I can manage tonight. I'm an hour late home though and really want to put out a new release of the firmware. I also want to try your stuff and play with GIT too.

Well done mate! :-)

Works a charm.

Two reset packets sent, one with each mechanism.

This is talking to the old code for now. I have no idea why, but the new code reset is still shagged and I need to solve that.

Packet structure hasn't changed with my messing around though. I still need to tidy up some loose ends on the ECU side. No release tonight, but perhaps I can get something with some functionality out by the end of the weekend.

So I wanted to test the red button, I found the git thing, but when I clicked download, it didn't appear to do anything. I'm not logged in, do I need to be? Could it be a browser bug, I'm using opera.

Thoughts?

For windows machines -

EDIT: You may need to this on certain windows machines - so go ahead and install it first

This step is optional-

If you dont want to mess with git just go to this page and download all the files (preserving the directory structure) - this is the source code......
http://github.com/srynot4sale/freeems-tuner.git/

Install python (all 3 packages needed) -
http://www.python.org/ftp/python/2.6/python-2.6.msi
http://downloads.sourceforge.net/wxpyth ... 1-py26.exe
http://sourceforge.net/project/download ... e&14958221

And then go to the directory where you downloaded the source code and double click on main.py - for me that actually leads to a crash - so i right click and select "Edit with IDLE" and then choose run from the menu....

I'll do that when I get home, I also see you note python 2.6, I just downloaded 2.5 because the wiki notes 2.5. Perhaps the wiki could note 2.5,2.6 indicating what versions it works with?

[shameem]

I downloaded 2.6 because that's the latest version that can work with wxpython and pywin32....
For 2.5 - wxpython 2.5 compatible and pywin32 2.5 compatible should be used....
Python latest release is 3.0 or something like that.....

Thanks shameem for those instructions for us Windows users. May I add that the PyWin installation package does not like to install unless it is run from the Python installation directory. I had to move mine to get it to work. Maybe add that to your instructions for us knuckle draggers.

Trying to run FreeEMS-Tuner after following shameem's instructions and I'm getting the following error when I try to "Edit with IDLE" then Run.

This is with WxPython (ANSI) installed. I first tried with WxPython (UNICODE) installed and got basically the same error.

Just trying to join the fun. =/

That's odd - for me it installs right out of desktop - i just tried it in a different computer and it works there too.....

Looking at your error msgs - it seems wxpython is somehow not installing properly .... it cant find its core dll...

Can you uninstall everything and do a clean install.....

Also unicode version is recommended ... i think...
