Has anyone tried to use PalmLog with a recent version of MS2 Extra code? It seems to be giving me nothing but problems. I have a DIYPNP unit with the 3.1.1 code and I can't the thing to hold a steady connection. I've gone into the preferences and set the RTU size to match the one in my INI file, but no mater what I do it seems like it connects for a second or so and gets a capture of the data (although most of my temperatures are still screwed up because I haven't set the calibration factors) right before it disconnects again. I can't log anything since it stops logging when the connection drops.

It doesn't look like PalmLog has been touched in about 4 years so I guess I shouldn't be surprised if it doesn't work, but I was curious if anyone here had gotten it working with recent MS2 Extra code or if it was just a problem across the board. If it just flat out doesn't work any more (and there was enough intrest) I'd be tempted to see what I could work out with logging to an SD card (and getting rid of the annoying HB++ log screens).

Should PalmLog work with recent MS2 Extra firmware? If it doesn't, would anybody be interested in an SD card logging application for a Palm m125 or m500?

Hell yes

I used palm log a few years back when I was using the 029 MS1 code. I attempted to use it with the HI-RES MS1 code and changed the correct things, but it still managed to completely corrupt my firmware at one point and make my car inoperable until I put a new chip in.

Not worth the trouble IMO.

I think it would be great if there was a small portable device that you could hook up to the megasquirt and have it datalog data to a SD card or such.

I had nothing but trouble with palm log, therefore, i no longer use it. I am waiting for an android interface.

I was looking for the same kind of thing too in terms of portable logging. I really want to take logs during HPDEs and autocrosses as it's one of the few times I'm really winding out the car, and if something happens I want to be able to take a look at the data and correct the situation. There's no way I'd pass tech with a laptop somewhere in the cabin unless I worked out something REALLY crazy for mounting.

I'm not holding my breath waiting for an Android, iOS, or any other modern handheld to get something that meets my needs. For one, none of them seem to have native serial interfaces. I'm cheap, and if I can get a device off eBay for $30 that will do what I need it to I'm not even going to consider working on a $300 or more device that I'd have to hack around some odd hardware solution to support.

It does sound like PalmLog may be a bit of a dead end, though. Next time I get some time I'll see what I can hack up just to make sure this is feasible with what I have.

I made a portable logger that I use at autocrosses. I would consider making them for folks.

bearda

Can you say a little more about how it works, and a rough idea how much you'd charge for one?

Techsalvager

do want

JustinHoMi

It's a black box with a serial cable, an LED, and a toggle switch. You just plug it into the megasquirt and flip the switch when you want to log. It saves to an SD card.

The "catch" is that I haven't taken the time to design my own circuit board or box. So it's using off the shelf components, which drives the cost up a bit. It's also a little bit of a pain to remove the sd card (you have to open up the case to get it out).

I'll have to add up the cost of parts, but it'd probably be about $100.

*duino based?

Yup!

Turboroach on this forum was working on one a while ago for both MS and adaptronic. Seemed like an awesome idea, but he got busy with life and whatnot and I never saw what became of it. I'm glad someone got one working .

JustinHoMi

It works great for MS-I, but I don't remember if I took the time to get it working for MS-II. It's been over a year since I've used the thing, and shortly afterwards I wrote an Android app to do the same thing (which does work with MS-I and MS-II). So I've just been using the Android app.

It won't take much time to add MS-II support to the logger though.

How do you interface with the android's USB port? Or are you using bluetooth?

JustinHoMi

I'm using a bluetooth adapter. I don't know that there is any good way to use the USB port.

I dug out my old copy of CodeWarrior last night and started playing around with it. I'm still a ways away from having something with a base level of functionality, but I can write dummy files (FRD format, but BS data) to the SD card and pull them out from my laptop.

I'll start working the serial data stream this weekend. With some luck I should have something up and running within two or three weeks.

I've been working on the logging application for the last week or so and just about have something ready to release. Right now support is limited to what I have to test with (MS2/Extra and PalmOS 4 devices with SD cards) but once I'm confident everything is working correctly I'll expand it to support other devices and MegaSquirt versions.

I ran a quick test this morning on my way to work and captured around 4000 records in a little more than 12 minutes, so it looks like I'm getting around 5 records per second. TunerStudio captures about 16 per second on my netbook for comparison. There's a lot of room for improvement in the code, though, so I'll see where it can go from there.
