I've checked all my pockets and I can find no Palm...but I have an iphone.


I may pick one up though. Pics of the ve and spark tables on the palm?

If the software existed, how would we hook up an iphone to the car? Is there an adapter cable?

Sorry I'm an iphone n00b.

The power/computer cable has a usb at the end. So one would just need a serial to USB

Asus EeePC and in car and done.

I'll do a post of my overall setup once done.

In car digital dash of sorts and GPS datalogging for track.

Or you could use bluetooth. If you're gonna write a new app, why not? I'm kinda surprised that the iphone crowd would even consider using something as "primitive" as a USB cable.

holy driver

I've done a little research on this front and one thing that's a PITA is that the hardware interface for the iPhone is closed. You have to sign up with Apple if you want access to the docs on the port and/or bluetooth hardware (you don't need special access to do phone to phone bluetooth, just for other devices). That said, I'm sure some enterprising folks have got it reverse engineered. It will just then require a jailbroken phone since you'll be accessing the hardware in an unapproved way. I recall that there was one guy working on some kind of iPhoneOS megasquirt software on the ms-extra forums, but I don't know what became of it.

Sorry Hustler, but thats one more reason to go Android. I can use certified apps in the market place, or use third party apps of your design or anyone else without apple or tmobile voiding your warranty. Apples dictating is tiresome

I'm a long time mac using graphic artist masquerading as a mac using sales engineer, but even I'm fed up with Apple demands on how I can use my hardware. ( I bought it, its mine!)

I've considering working on an app for the G1, and other Android enable phones, but again the interface is a bit of an issue. My MSPNP uses a serial connecting. I know some of the other Megasquirter builds offer full USB capability, but the I don't think that applies to the MSPNP. I don't know if any MS supports bluetooth although that would be a great option if things change.

Reading the above post.. why is it that MS uses a serial connection anyways.. USB ftw.

I don't know for a fact, but I think it is because thats what was common when it was first developed. In addition it was really easy to find an older laptop with a serial port a few years ago. However things have changed. On the non PNP builds I know you can adapt usb, and I would think you could do this to the PNP as well, but you would have to talk to guys at DIYAutotune for that info.

this would be something i'd be interested in as well because i'm too lazy to lug my laptop around with me and don't think it's a good idea to leave it in the hot car all day

RS-232 is still a very common standard on embedded microcontrollers, largely because it is easy to implement, has very low overhead, and is entirely adequate for the sort of low datarate tasks that these processors typically perform. Both the 68HC908 (MS1) and the 9S12C (MS2) processors natively speak RS232 on dedicated pins, requiring only a simple line driver to interface with the outside world.

USB, by comparison, is somewhat more complex to implement and has a higher overhead, and is thus not commonly seen on processors intended for embedded devices.

There are several low cost single-chip USB interfaces available for use in designs like the MS, and nearly all of them consist of a USB to RS-232 transciever which appears to the host PC as a virtualized COM port, and appears to the microcontroller to be a normal RS-232 terminal. I'm pretty sure that this is how USB is being implemented in the new MS3 design, although the schematic does not seem to be available yet.

Writing software for handhelds is a pain in the *** and usually involves buying expensive development kits.

It is not true that iphones run mac os x in any useful sense.

Thanks, that makes a lot of sense.
Once I get done with this freaking deployment I am getting back into software dev. a lot of my side projects will hopefully be automotive related

Yeah, while a lot of folks seem to view USB as being "simpler" than RS-232 (for reasons that I still don't understand), from an engineering standpoint, both hardware and software, RS-232 is 1,024 times easier to deal with.

apariah

I think the problem is most if not all new laptops/netbooks come with usb vs. Serial Rs232. This forces you to use an adapter that may or may not work. Was pretty fortunate, my setup seems to works fine serial, or usb, but I also purchased my adapter through DIY Autotune.

Sorry, threadjack, back to your regularly scheduled thread.
