Will upload the initial software in a few hours .

 

Cool XD

Should the gauges be running close to real time once it's closer to a final version?

 

Yes I hope so , I need to play arround with the refresh rate of the interface . And also assign more ram to the GPU . Won't be able to test much this week , as I am going on a business trip tomorrow . Only gonna be able to test again the weekend after next . Just wanted to upload my progress and start getting some donations , as it's really expensive to do this alone for me . Post your experiences and play arround with the refresh times

 

Having fewer gauges on screen at one time may improve response

 

Yes will also try that . The final release will have 4 dash boards that can be switched , so no need to have all gauges on one screen .

 

Hope I get some feedback from people who tried it

 

Hi guys ,

Quick update :
Version r3 is in develpment with new features :

-4 free configurable dashboards that can be switched while running
-Logging of the following values as CSV file (can be used in Excel) to USB :

-Engine Speed (rpm)
-Absolute Intake Pressure (Kg/cm2)
-Pressure Sensor Voltage (mv)
-Throttle Sensor Voltage (mv)
-Primary Injector Pulse Width (mSec)
-Fuel correction
-Leading Ignition Angle (deg)
-Trailing Ignition Angle (deg)
-Fuel Temperature (deg.C)
-Metering Oil Pump Duty (%)
-Boost Duty (TP.%)
-Boost Duty (Wg,%)
-Water Temperature (deg. C)
-Intake Air Temperature (deg C)
-Knocking Level
-Battery Voltage (V)
-Vehicle Speed (Km/h)
-ISCV duty (%)
-O2 Sensor Voltage (mv)
-Secondary Injector Pulse Width (mSec)

It would be nice to get some feedback of you guys eg .
Have you tested it on a raspberry pie or linux pc ?
How does it perform if ran from a normal linux pc ?

Without your feedback , i can only give my input to the developer

 

Sorry guys , just realized i haven't uploaded the programm yet ,
Just change the file extension from XML to zip and extract .
(forum only allows 100KB zip , but 1.9 MB xml files )
Make sure you read the readme , as the path where the files are is important

Have fun testing

 

Hello Markus,
I am the administrator of the community RX-7 France. First of all, congratulations for the work done, we discussed a similar project in your power to do without all the ugly and useless gauges in our cars. Do you think it would be possible to help you in your development? We have some ideas for graphics with a purely digital data display power FC to stay in a sober and legible aesthetics. Thank you in advance Markus, congratulations.

 

Hi Tony

Thanks for your interest . I would apprechiate any help possible , donations would help a great deal , as it is really expensive to pay for all the development on my own (over 400 $ of my own money already ) . The source code will be made available by the freelancer i hired after all the contracted work is done (i hope in 2 -3 weeks ) . In the meanwhile i would apprechiate if people would test the software , as i have lots of other tasks to do and don't really get to any testing in the next 2 weeks ( UIM and turbo pipes out for polishing ) . Please play ouround with the refresh rate in the config file and see how low we can possibly go to get a smoot display . The source code will be uploaded on google code . Anyone interested in developing this further after that is welcome to join .

You can donate via paypal to Markus.Ippy@gmx.de (every little bit helps )

 

Hi Guys

Just received -r3 from my developer today

Newly added :

You can use now 4 Dashboards
Automatic logging with output to a CSV file

I will upload -r3 for testing today

My developer is busy cleaning up the sourcecode now , and will upload it on the weekend onto google code :

https://code.google.com/p/raspexi-viewer-linux/

 

Here the link to the R3 binaries

https://onedrive.live.com/redir?resi...54082B4E%21108

Enjoy

 

congrats on getting the raspexi viewer going i my yet to get my car running but i will be working on my car and getting it running by june so as soon as my classes end in 2 weeks i will get to work on my car and hopefully be able to test it.

 

Thanks man , haven't tested R3 yet got my UIM and boost pipe only back yesterday from polishing . Will get new air filters next week , so I hope I get time to test properly by end of next week . Still need to assemble the UIM

 

what raspberry pi unit are you using? which do you recommend?

 

I use a model B , still need to play arround with less gauges per screen as it is a bit laggy still

 

The latency you see is quite possibly a result of the PowerFC itself. The communications protocol on the PowerFC is ungodly slow. The data rate of of the datalogit to the PowerFC is not even close to the data rate of the datalogit to the PC. To effectively generate a graphical display like this you need to use a form of command queuing that prioritizes critical information queries over less critical information.

For example:

Query Basic
Query Basic
Query Advanced
Query Basic
Query Basic
Query Sensors
Query Basic
Query Basic
Query Advanced

I use a method similar to this for a program I wrote for OSX that works very well.

 

Thanks for the tip , i finally got time to test R3 today and its still laggy even with just one gauge . Here the video


Sorry for the source code delay , it should be finally uploaded this weekend , hope someone with programming skills can improve it and make it work better

 

Is it still requesting all the info from the PFC, but then only displaying it on one gauge?
As opposed to requesting only the specific info that the one gauge requires

 

Thanks slacker . I hope the source code is online soon , then we can have a look at that

 

Hi guys ,

My developer pushed the source code today to google code , sorry for the delay .
This is as far as my develpment will go . If you are interested in carrying on and improving the code , send me a PM and i will add you on the google code project page . The source code can be found here
https://code.google.com/p/raspexi-viewer-linux/
I hope some of you with programming skills will help me to take it further
I also attached the source code in this post

@ $lacker hope you can contribute with your ideas

Regards

Markus

 

I wish I could help, but I can't code unfortunately
I sent a donation a few weeks ago
Hopefully there's a programmer with an interest in the FD that will get involved

This is coded in C?

 

Thanks for your donation slacker , I only saw it now . Yes it's coded in C . I also want to learn programming myself , so I also hope I can browse through the source and make changes . Have anybody been able to test it ?

 

i started working at this company and theres tons a software developers if you could shoot me all info that you have collected maybe i can have one or a few developers take a look and see if we can get this running smoothly. i cant wait till its ready.

 

how well will this work with the datalogit?
