TPMS (tire monitoring system) plugin

[f1racr]

Yes you can use that kit. Alok has developed / made that kit which is one you can purchase complete without having to assemble things. It's made to match or exceed Robbies initial design and is compatible with the plugin.

thanks f1racr.

Yes, Robbie did a great job with his modifications but it's too much of a challenge for me to built something that complicated (my skill level is not that advanced).

This TPMS Tire Pressure Monitor from Centrafuse Carputer, CarPC & UMPC Forums - Centrafuse Downloads - TPMS Tire Pressure Monitor

And I will use together with Centrafuse and a car pc, but could someone please tell me what hardware to use? Could I use some of these?
From Ebay Find Tyre pressure sensor on eBay International Market, with worldwide deals on items in all your top categories
And hook these up to the TPMS Tire Pressure Monitor and Centrafuse?
Or is not that easy?

@ RS4: No - you have to either use Alok's TPMS, or head over to Mp3Car Forum, and search for RobbyBMW, he started this project, and you have to get your hands on a 3rd Eye TPMS kit, and then a pre-programmed PIC Micro, make a PCB, and hack it together.

Alok's device is much more pro (not to detract from Robby's idea), as there is no hacking involved.

If you want to go the DIY route though, I have documented the procedure here in my project log on how to do the hack.

Please be advised, that as of now, there is no plugin for CF3 available yet - they guys are working on it

FYI i have all but 1 line of code converted to vb.net for CF3.. and i need help on this last line:

C#

//--------------------------------------------------------------------
							// Get the transmission reason
							//--------------------------------------------------------------------
							Tire[n-1].TxReason = (Reason)inputReport.Buffer[4];

vb.net (automated translation)

'--------------------------------------------------------------------
                            ' Get the transmission reason
                            '--------------------------------------------------------------------
                            Tire(n - 1).TxReason = DirectCast(inputReport.Buffer(4), Reason)

the vb.net translation errors to:

Error	6	Value of type 'Byte' cannot be converted to 'TPM.TPM.TPM.Reason'.	E:\Documents\Projects\TPM\TPM\TPM.vb	646	63	TPM

anyone have a better translation of the c# line?

If i can solve the error i should have a working TPMS for CF3 ... pending the TEDIOUS conversion of the skin.xml.

I'd love to use this on my truck, but it'd need to monitor a minimum of 10 tires (18 if I monitor the trailer tires).

Try this first:

Tire(n - 1).TxReason = CType(inputReport.Buffer(4), Reason)

If that doesn't work, double check that Option Strict is off.

If "Reason" is of type String, these two functions might be of use:

Public Function string_to_byte(ByVal Data As [String]) As [Byte]()
Dim encoding As New System.Text.UTF8Encoding()
Dim byteArr As [Byte]() = encoding.GetBytes(Data)
Return byteArr
End Function

Public Function byte_to_string(ByVal Data As [Byte]()) As [String]
Dim encoding As New System.Text.UTF8Encoding()
Dim strDest As [String] = encoding.GetString(Data)
Return strDest
End Function

The DirectCast results that the online C# translators provide seems to be a problem in many cases.

Sonic, it's awesome to see someone working on this plugin for CF3.......

Thanks so much for taking the time to work on this. I'd be happy to contribute to your efforts once you've got a working version...... I think it's only fair for people here to contribute towards these plugins.

Thanks again

Got the hardware now from Djean thanks for shipping
Any update on a CF3 plugin

[Sonicxtacy02]

expect a plugin right around the time 3.1 is released
