They hopefully put out via an RS-232 serial port or CanBUS.<br /><br />Communication Path: An Android phone can read data easiest over Bluetooth. You will need to find an adapter from the controller and battery pack output to Bluetooth, as I've done above. An Android-based PC likely has RS-232 serial ports or USB and you'll need the correct cables or adapters.<br /><br />Software: Once you're getting data into the device, you'll need to parse it based on the protocol defined by the device. You'll need the protocol definition to properly read and interpret the data stream. If you don't have the documentation you'll have to reverse-engineer it. You can then use this data to drive the gauges.<br /><br />I hope this helps. Feel free to email me directly if you need more help.Michael Brownhttps://www.blogger.com/profile/13907618944840338910noreply@blogger.comtag:blogger.com,1999:blog-8858445023207964067.post-81344954089878654452012-12-10T23:31:17.409-08:002012-12-10T23:31:17.409-08:00hi.

(note: ive been programming computers since 1979, so im adept at reading/writing code).<br />thanks in advance for any help you can provide.<br />johan@hilltopauto dot biz<br />johanhttp://hilltopauto.biznoreply@blogger.comtag:blogger.com,1999:blog-8858445023207964067.post-62584062827831378332012-02-27T12:16:29.598-08:002012-02-27T12:16:29.598-08:00Rikard, I tried to use the app in my first real dr...Rikard, I tried to use the app in my first real drive of the car yesterday and found a bug with the data flow handling.

I'm converting a -73 Fiat 500 R myself and since I own a paktrakr 600 I would love to test your app. Is it possible to get a copy of the app? I use a HTC DESIRE HD with Android 2.3.5.<br /><br />Please se my blog at luigi500.blogspot.com<br /><br />Best regards<br /><br />rikard.westlund@gmail.comriwehttps://www.blogger.com/profile/14225933081936188416noreply@blogger.comtag:blogger.com,1999:blog-8858445023207964067.post-21702883720884211362011-10-17T21:45:10.311-07:002011-10-17T21:45:10.311-07:00Zane, as we discussed over email, I'm happy to...Zane, as we discussed over email, I'm happy to contribute my code to your project.

In the short term I think it would be easier to make a custom version for your layout. <br /><br />Email me a description of the physical battery layout and Paktrakr remote battery layout when you get a chance.Michael Brownhttps://www.blogger.com/profile/13907618944840338910noreply@blogger.comtag:blogger.com,1999:blog-8858445023207964067.post-60890017228790049212010-06-14T15:32:19.937-07:002010-06-14T15:32:19.937-07:00WOAH!

I was going to go with the EV dashboard on a windows ce gps device (already bought it in fact) but using my android phone (EVO 4g) would be SO MUCH MORE CONVENIENT!!! I would love to test this out as you develop it, if you need bug hunters. I'm currently still building my EV from a 1986 Mazda RX7, working on metalwork/fabrication right now. Please keep posting on the development of this app, it's looking amazing!<br /><br />Will the individual battery breakdown be separated by remote? Please feel free to email me, I would love to talk more about this project!<br /><br />jason@frankencar.orgUnknownhttps://www.blogger.com/profile/01800840514495540193noreply@blogger.comtag:blogger.com,1999:blog-8858445023207964067.post-38179021164693963732010-04-10T10:52:09.328-07:002010-04-10T10:52:09.328-07:00I look forward to that Steve!

Love the software add-ons. That's brilliant. I look forward to a tandem ride in our electric Porsches through the mean streets of San Luis Obispo!Stevehttps://www.blogger.com/profile/01910595180093275632noreply@blogger.com
