Re: CAN controller

Hmm... I'm a newbie but I think you guys are over thinking this. An STN1110 chip is $10 and interfaces with the ECU, and supports all OBDII protocols. I need ISO for my car, as CAN wasn't implemented yet (2002 Acura), but the STN is good for all of them. It also accepts up to 5V input, but is meant ...

Re: Newbie here... looking for help (Carputer)

I've been figuring out quite a few things. For the OBDII interface, which I figured would be the hardest part of all this, well, turns out it won't be so bad. I plan to buy an STN1110 for $10(+Shipping) which will communicate with the ECU, and then all I need is a simple program that sends "AT" comm...

Re: OBD-II STN1110

As I research more, and think about it, I'm starting to feel that I should buy an Arduino as there are already many people successfully interfacing with their ECU and using LED displays to readout information. It's exactly what I want, and I'm thinking it might even be better overall to leave the Pi...

Re: OBD-II STN1110

Learning so much here. Really great. So, I found an open source software called pyOBD (written in Python) that can interface with, apparently, any ELM chip: http://www.elm323.com/pyobd There's also some great info here on making your own board to interface with it, as well as other software. http://...

Re: 5v rail on computer psu for power

If it's a terrible PSU, then maybe don't do it, but it should be ok. Many people power their RPi off a PC's regular USB connections. I guess it depends how you hook it up.

IP-Bus to GPIO Idea (Control Pi with Car Head Unit?)

Hi guys, I've got an idea but no idea how to implement it. I'm currently using a Pioneer DEH P6900UB head unit, it's a single DIN CD player with multiple input/outputs. At first I thought maybe I could connect to it with the USB, which is used for iPods and USB Flash media playback, but I highly dou...

Re: Overclocking

This topic is relevant to my interests. Many people have posted how they raised arm, ram, and core freqs but no mention of gpu freq, so that's why I wonder. If it just sticks to 250 without manual modification, then it seems that it would be less stable with a raised core_freq. That's pretty much r...

Re: RasPi power usage measurements ~2 watts at idle

I'm really curious where this is going. Will the RPi have an auto sleep/wake function based on a GPIO input? Would be extremely helpful for a Carputer scenario, although I suppose a secondary logic controller like, perhaps and Arduino?, could do the job. I really don't know enough to know what is an...

Secondly, Dom is considering a GPIO switch for auto sleep/wake! In theory yes. Trouble is we are...

Re: OBD-II STN1110

Hi, newbie here. What is the point of this/these chips? Why not interface with the standard OBDII output? Would you not simply require a software that can read the data?

Re: Raspberry CarPi

I definitely like the look of that Samsung touch screen. I think for a Carputer, it would be a bit silly to forgo a screen since you can do a lot more than just play music (in which case, you can just plug in an iPod or whatever). For example, GPS and OBDII data. The question is whether a touch scre...

This topic is relevant to my interests. Just curious, as this doesn't seem to have been explicitely covered.

Re: Monitor Advice

Noob here, but I can help a bit. The RPi does output power through the USB, but it is minimal, like 500mA. This would not power a monitor AFAIK. So the best thing to do, I think, is get a powered USB hub. You can also probably find a 12V-5V DC electronics kit and run the RPi off your batter line, or...
