Thanks! That should be all the information that I need. Bad thing is, I won't be able to do any testing until I get some hardware, is it available for sale yet?

Of course. You have several options:

1) I can provide you the PIC with the firmware already inside and the PCB, then you will have to bought all the electronic components, the 3rd eye TPMS kit, and assemble the device. (Send me a PM if your are interested in this option).

2) You can try to contact DEJAN (a member of this forum) and ask to him if he has yet some whole assembled divice for sell.

3) You can ask to LYHTSPD (another member of this forum), which has produced a smal series of these devices for the people of the forum.

I have a Mazda CX-7 with OEM TPMS, I would love this on my car pc screen, anyway to hack the OEM signal? If I replace my OEM TPMS I will get a CEL

In theory it would also be possible, but this would lead to start from zero the development of a new USB interface.

A new version as been released in the first post of this thread.

1.20:
- Fixed the issue with sliders when multiple plugins are loaded. (More informatinos on this thread)

It´s great!!!So, what hardware I need for this?

Hi Robby BMW,

Could you please share a picture that you used in the RR config? (a car with tires that are numbered withing 1...4) ... if it's possible :-)

Robby BMW · 08-04-2008, 01:20 PM

A new version (1.30) as been released in the first post of this thread.

Here you go

I have just installed the system and I think the learning worked. But I have not installed RR yet as I want to make sure all hardware works first.

Can I somehow start the skin without RR? Or is a simple exe that loads the dll required? Does it exist already?

No, but you can use "TPMS Doctor" to test your hardware without RR.

Yes, off cause! Sorry.

I've tried it now and it worked. I must say that the TPMS has been the easiest to install of all functionalities I've installed.

I do have some problems getting updates from the sensors, aspecially the sensor closest to the reciever, but I'll read thru the threads and see if I can find something there.

Thanks

That is strange because normally are the sensors farthest that could have some problems, maybe you need an external antenna.

Hi Robby

Thanks for your effort!

I am considering an external antenna according to your previous drawing but I also think there might be a problem with the learning usecase....

I have relearned my system several times (without doctor and config up at the same time) and this time it is wheel 2 that causes me problems. In fact I get only one value at learning and then it is silent. (If I erase data it stays with question marks. See below)

[media]http://web.comhem.se/mulle4/TPMSDoctor.jpg[/media]

Q1) Could it be that collision makes the ID wrong and then the sensor is never seen again? Or do you have retries? Should I maybe deflate below 1,5Bar and back again to force sensor into "init mode" to get more frequent updates?

Q2) Why is this? I have observed (by accident) that the abort prompt sometimes goes away before I've even started to deflate the tyre, or VERY soon after I've started. I become very suspicious that a valid learning really has taken place.

Q3) If I have a problem with one sensor, do I have to relear all tires or can I just relearn that tire? Unless the ID is already used I don't see why not.

Q4) When I use TPMSDoctor on my 480x800 display the bottom gets cut-off entirely and I do not get access to the buttons at the bottom. I then have to violate the screen resolution with 600x800 (which will give the screen a nasty offset) when I need to use them. Can I please get a smaller layout version? (Am I really the only one that has had problems with this, or am I the only one rude enough to ask?)

Once I am at it, I would really like a timer on all sensors in TPMSDoctor to show have many seconds that has passed since last update. Or something else that has the effect that I can get an idee of how well the system is working.

I have read thru this thread at last and I have put some gold nugget post links here.

Edit:
I just seen in post one (:-)) that there is a 16 bit CRC in the message so the learning should not get confused by collisioned messages. (Why not show ID also in TPMSDoctor? Or save all traffic in a log file? Is it not sent from pic to PC?) Still, something seems to be wrong with "learning".

(btw. I only count 12 bytes)

Edit 2:
Since we know that we will get one transmission every 60s in normal mode we know if messages are lost. This could be used for finding best position for receiver/external antenna. A percentage calculation in TPMSDoctor maybe?
