How are you folks powering your Pis in a permanent install? Is there such a thing as a micro USB cord that can be hard wired into a 12v power source in the car?

This really makes me want to get this running on iOS. I like the idea of just having some aux data available on an iPhone rather than having to hardmount a screen somewhere. That way one could declutter the dash when you don't need to, e.g., watch temps carefully. My main interest in this thread is actually just getting rid of the rattley, gameboy-looking PFC Commander so I don't have to see it on my dash anymore.

So obviously this is slow on VNC. One alternative would be to just do a native iOS app that looks for UDP packets or something like that over bluetooth, but then you have to write a whole app, handle the data, display the gauges from scratch in a non-ugly way, etc. I wonder instead how difficult it would be to spoof a wifi or bluetooth OBD II dongle and then connect to the raspexi via any one of a million iOS OBD scanners. So the app could just get the PFC/aux data in the form of spoofed OBD PIDs instead. DashCommand, for instance, would allow you to easily make a custom dash, log data, etc. Would be great to take advantage of some of these really robust apps already out there rather than reinventing the gauge wheel.

 

So to answer your power supply question . I ordered myself a car power supply from here :
http://mausberry-circuits.myshopify....upply-switches
It has Gipo outputs and a can "sense" when the ignition is switched off . It will then keep the power on and trigger the pi to shut down , after that it will cut power . I ordered mine last week and wait for it to arrive , will keep you posted once it's here . With regards to the IOS app , this would require to write a complete app and cost a lot of money to commission . You could try to find a open source obd emulator and convert the Apexi data so you can use it in one of the many OBD apps , but that's a whole other project .

 

On a more exciting note , I am busy commissioning another feature . GoPro start stop recording triggered by Raspexi . This would allow Raspexi to set a marker in the log file when you start and stop recording . Therefore you can take the log file and the video and overlap the data in racerenderer. It's fairly easy to implement as the GoPro can be triggered by via simple http commands . Hope to have this feature in by January and post a nice track day video by end of Jan .

 

That's a great feature idea. I've got a gopro I'm hoping to play around with a bit too.

I think I'll try VNC as a stopgap while I configure the rest of the setup and decide whether I really want to do iOS vs an in-dash HDMI screen. Slow response time would be OK for me because I mainly want to check slow data like temps: IAT, coolant, etc.

 

Just got the first compiled version from my developer for testing . Could unfortunately not test in the car as its at the body shop for a paint job . GoPro 3 and 3+ are now supported Implementation was 70$ if you whish to donate

 

Source code with Hero 2,3,3+ support is uploaded to github . Enjoy testing . https://github.com/MarkusIppy/raspexi-viewer-linux
Hero 4 is not supported yet as it uses different commands than the previous hero cameras

 

I made a new image yesterday based on the latest official Raspbian Jessie image and the latest current source code . It boots directly into Raspexi in about 23 seconds . This image works on Raspberry pi 2 but should also work ona pi 1 model b ( please let me know if you have a pi 1 and confirm it working ) . It also has Megatunix pre- installed to create your own gauges . Just boot the image , quit Raspexi by pressing "q" . Type "Startx" to launch the desktop . To setup your GoPro wifi , just click on the wifi logo on the right top on the desktop and enter your wifi password and it will automatically connect on the next boot .
After that just configure the raspexi.cfg accordingly in the folder
/home/pi/raspexi /

To install this image :
Unzip the image
Have a at least 4GB SD card
In windows , download win32 disk manager
select the unzipped image
selec your SD card drive letter
click write to disk
After successful writing , insert into your raspberry pi and plug in the power cord

Please give me feedback on how this works for you

A early merry Christmas . Ho Ho Ho

 

I had a idea to make Raspexi display the values from the Power FC on virtually any Device and any OBDII app .
I stumbled upon this open source software :
OBDSim

As far as i can see it allows you to write a plugin for OBSIM that effectively coverts the data to a OBDII readable format and in turn can be readout with one of the many OBD Apps on a mobile device .

Anyone willing to write a plugin for OBDSIM ?

 

Scanning through, but seems this isn't as easy as haltech?

.

 

Unfortunately not . The power FC was never meant to have a animated display .

 

I tried to use the image but it gave me problems. I have the program running great.

How did you turn off the screen saver?

How did you get it to start at boot?

Thanks

 

Hi

I just followed this tutorial

http://blogs.wcode.org/2013/09/howto...browser-kiosk/

It uses matchbox window manager and starts your program at boot . Just changed chromium path with Raspexi path . May I ask what in my image did not work for you ? We tested it on pi 1 and 2

This seems like a very interesting interface for the power FC , unfortunately Google translate sucks . Seems it is a Bluetooth interface for the power FC

 

Thanks

I think the problem is my sd cards or reader. The card that came with my pi 2 already had the os installed. When i wrote the image on my other cards it booted and worked once then gave me mm0 errors when booting after that rewriting the image did not help.

 

Hi Markus-

First off, great project! Your latest image is running very nicely in my WRX setup. I've changed a couple of the dashes to suit my needs and I get a lot of comments on how smooth the gauges look.

Is there a way to set up a gauge to show peak values? I have the FC dashboard set up, which serves as a very clean replacement for the FC commander, but I like being able to see what my max knock or MAF voltage was after a run.

I'll put up a video of my setup in action in a few days.

 

Thanks a lot for your feedback . May I ask which model year and engine your WRX is ( like to add it to the list of tried and tested cars ) . I would also like to repost your video on the Raspexi Viewer Facebook page with your permission . Excited to see your video

 

Sorry yes you can set peak values in gauges ( but only if you use analog gauges that have a needle ). If you right click on the screen you can select tattle tale ( this will show the peak values ) . Unfortunately this won't work on gauges without needles

 

My car is a 1999 JDM Subaru Impreza WRX GF8 EJ205G - Power FC model EJ207. Of course you may post my video, once I actually go film it that is... I have a friendly drag race tonight so I'll try to get footage of the gauges in prime form!

I will give this a try and see if I can make an analog knock gauge.

What is needed to be done to implement Hero4 support? I am willing to either help or contribute to getting that working.

 

Hi Hero 4 support should be pretty simple to implement . In essence its sending a request via HTTP , GoPro 2and 3 have different commands than Hero 4 . I don't have a Hero 4 , so please do the following for me . Switch on the GoPro Connect your windows PC or Laptop to the GoPro Wifi ( just connect to the GoPRo Wlan like you would to your home Wlan ) .
Then open a browser window and type the following text

http://10.5.5.9/gp/gpControl/command/shutter?p=1

This should start the GoPro recording

http://10.5.5.9/gp/gpControl/command/shutter?p=0

This should stop the recording

Please let me know if these commands work , if they do we can implement GoPro Hero4 with not too much efforts

 

Any updates on this project? Just purchased my Raspberry Pi and looking at screens for it. Excited to try in my S4 n/a bridgeport running PFC.

 

Hi , there has been no new additions in terms of features . The software runs smooth with no known bugs . The software was released as open source so that others could add features And improvements . Unfortunately only Sonic Rat and Jacob D. Have done contributions so far . So if any of you have programming skills and want to add features send me a pm.

 

Haven't tested yet so no feedback or suggestions so far. Hopefully will be loading it up this coming weekend with my shiny new RP 3 and 10" LCD. Have you tried running the RP 3 to see if the newer processor has any effect on boot time or responsiveness of the gauges?

 

I have tested on pi2 and 3 boot time is not much faster on pi3. Jacob made a good image which boots into Raspexi in approx 10 seconds .its set to Nissan by default so you need to modify the cfg to Mazda
