The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.
Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.
However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. What has changed is that the method of MegaSquirt support today has rapidly moved to Facebook, this is where the vast majority of interaction is happening now. For those not on Facebook the msextra forums is another place for product support. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.
Sorry, PalmLog is written specifically to communicate via serial port. The source code is freely available to others who want to extend the functionality further.

From the first post in this thread it looks like the M500 has TTL capability, so if the M125 also has that capability, then you could use a MAX232 chip to convert the Palm's TTL to RS232 to talk to the MS. There may be other ways but RS232 communication is pretty well rock solid. An alternative to the MAX232 is the DS275 chip I posted on page 1, available from RS Components in Oz, it doesn't need the 4 external caps, and steals power from the RS232 lines. However it probably won't run fast enough for MS2 datalogging applications. If you use a MAX232 you could use 5V from the MS and run that up the serial cable. The MAX232 is fairly bulletproof so go that way if in any doubt.
Just for info for this thread, I recently got a Tungsten T, it does RS232 no worries, and is a very strong, quality unit. Everything on it works better or finer than the Palm V series and Sony Clie that I am comparing it with. What I also like about this Palm is it has the best screen visibility I have seen in daylight or shade, good battery life, compact, strong!!! (don't ask me how I know) and fast with a 144MHz processor. I see they are still fairly cheap in USA.
So the Tungsten T will do the job without needing the TTL conversion chip?
I'm trying to keep things as simple as possible.
I have bought 3 second hand Palm IIIc's so far and none of them will power on. I'm awaiting a new battery, but I don't think its going to work somehow.
I am such an eeeediot.
I bought a serial cable and usb charge cable for the Palm IIIc from ebay.
It turns out that the charge cable had pin 10 as 5v and pin 9 as GND instead of pin 9 as 5v.
After switching the wires around, it actually powers on
It seems to me the PalmVIIx has the older non-upgradeable operating system. If that's the case, it won't work.
PalmLog supports MS2, but has not been tested with MS2Extra that I'm aware of. The actually logging portion of the program should work if configured properly in the setup screen. Displayed runtime values will likely be off, as that aspect is hard-coded in the PalmLog to suit each version of MS embedded code.

What operating system is installed on your Palm Viix? Do you know if it is the original OS, or was it upgraded? With that info I'll add details to the compatibility list.
Thanks,

the version I am running is 3.5.3
I dont remember what it was running earlier but I just went to the palm site and downloaded the latest OS upgrade i could find which was 3.5.3
I got a Palm to serial cable off ebay for 4$ they didnt have a cable for the VIIx so I got one for the Pam III.
Now I can use it without the docking station.
Im runing MS Extra. Ive set the ms2 v2.3 option on
Rtu=A
Bytes= 152
Havent updated to the PC yet. But it I do and face any problems Ive been told to use Bytes = 112
Runing MS Extra II.
Here is a good link for guys with old Palms to make sure they have the latest OS
does this work for you?
i tried without success. and i have a factory serial cradle and a serial hotsync cable, both not working.
finally i bought a Vx, working as expected
A tip for those who have Palm V or Vx, set up a shortcut to the digitizer with one of the buttons, that way if the Palm ever crashes or resets or the digitizer becomes difficult, just press the button and you can go straight into the digitizer to make it right. My V used to drive me nuts until I did that. After doing that, the V and Vx are a very good unit IMO.
yes, thats a great tip.
my other Vx makes that and it was like heck. but i found some other problems with it (can not upload anything, "not enough memory" with 7MB free out of 8MB ) so its laying around until i find a solution.
but one is working proberly so i'm not in a hurry ...
If it can't be fixed it will be good for spare parts. A clothes iron can soften the hot glue on the edges of the unit so it can be opened. Spare battery, screen, digitizer etc. I wonder if reloading the OS4.1 would fix it?
does OS4.1 work? i looked at Palm.com and read that OS3.5.3 is the newes the Vx could handle. the working one upgraded form OS3.5.0 to OS3.5.3 correctly, but the non working refuses to upgrade with "not enough memory" and i don't know any other way to flash the OS via hotsync, the way Palm describes on the webside. read that there is a debug mode, i can enter this but don't know what to do then
