Henry Nee came over to the hangar today and installed Ubuntu 10 on my EeePC
net book. What a transformation. It now has access to 1000's of free
programs easily downloaded and installed with a few clicks of
the mouse button. Thanks Henry.

There is a terminal program that runs on Ubuntu 10.
This is a first step getting the EC to talk to an Android tablet.
Both the EeePC and Android tablets run Linux as does the Mac for that
matter. Late Macs allow one to install Ubuntu and perhaps several
other Linux distros.

Henry  is also working on a hardware tap that will monitor the serial
traffic
between Ed Anderson tuning device and Tracy's EC. It should also work
with Tracy's EM.

Eventually we hope for a Megasquirt type graphical user interface on a
tablet
for Tracy's EC to make it easier to tune. In theory one could record many
mixture maps so they can be shared with others.

BTW Henry and I have a lot in common. We both started with the 6502
back in the early 1970's.

Hey Paul,

Did Tracy provide you any details of his communication interface, or are you
planning on reverse engineering it?

Thanks,
Brannon

Not so far. We did get some help from Ed Anderson and Perry Casson.

"Yes, Tracy has a set of EC commands and uses the MIDI format to transmitcommands and data over the serial link. " E.A.


"My many attempts to get things right always resulting in getting a few throttle settings where the engine would stumble. I found once there was a ?hole? in the map table they were very hard to fix as the engine would oscillate above and below the problem MAP pressure valueand saving correct data where the problem existed was hard to do. To help get a better idea what was going on I wrote a simple program that parses and displays the runtime data getting sent outof the EC2. Here's a look at the data I was able to pull out from the EC2 data packet and display."


"Unfortunately you can not plug the serial port of your laptop directly to your EC2 because a EC2 uses 5V CMOS logic levels not +/-12V as used by RS232 so you are going toneed to build a adapter circuit. I had few Maxim 232 line drivers laying around so that is what Iused. On the rainy day list is to actually make a short run of PCB's so I can have a permanentlymounted device in the airplane but for tuning purposes the breadboard approach works well. It would cost less that $10.00 in parts to build the following. For those you who are not familiar with electronics prototyping click here to see what a breadbread looks like, they are available from any electronics supply store."


"I've been working on a Pocket PC version as well with a plan to be able to use this as a inflight fuel totalizer among other things but it's still a work in progress."

"Note: The PC version is developed to the state where it is functional enough to be useful but there are several things like spinner controls, menus and the setting dialog that do nothing. For me it was good enough to get the job done as is so I'll probably not be doing much development on it until the Pocket PC version is completed."

"Important: This program requires EC2 firmaware that is dated Oct 2003 ornewer. To get order EC2 firmware updates contact Real Word Solutions"


To download the current Windows version click here: EC2Params.exe

To download the source code (requires MSVC)  click here: EC2Params.zip

"Note: Nov. 2010 - I while back I spoke to Ed Anderson who used some if this code to help with his development of his fuel totalizer.  Glad it was some use to someone - buthe did mention the newer EC2 firmeware uses a high higher baud rate - 38400 I believe he said." P.C.
