PEAK-System Forum

As the UDS Software Protocol is not a PEAK-System build solution, you need to study the USD Protocol Definition how to use the protocol. As we d not know if you use our Hardware, you need to contact us by e-mail with more information (we do only B2B) so that we could help you. support[at]peak-system...

As Keneth wrote - do not use the "getTickCount" Counter - this is the wrong reference !
Use the Windows PerformanceCounter Class - these are exact/precise enough. And so we also use this as time base.

If you define a Symbol like this [Vert_X28_NMT_HEARTBEAT] ID=750h-751h DLC=1 Var=s NMTState 0,7 Var=reserved unsigned 7,1 The Signal "s" is always the same ! If you reciece ID0x750 with valid Data, the signal "s" is set, if your receive ID0x751with valid Data the signal "s" will also be set. See Sym...

No Problem ! If the problem is solved, all is good

If you use the tracer option of the PCAN-Basic API, then the queue will not be cleared and you should read the data by CAN Read Function. If you build a own Trace functionality, and read with CAN-Read, you simply empty the queue. Please try the sample from the API Package.

When Read( .. ) return a dezimal 32, then no message is in the queue, and so no message could be read....

Check the return value of the function CAN_Read( .. ). What did you get? Please read the manual to understand this value - it is important that you always use the return values of each library function and check them.

Please send us a picture of your used PCAN-USB Interface to our support[at]peak-system.com address, incl. company details etc.
We will answer then directly by e-mail.
Thanyk you

If a Software Tool use the Hardware / Net , the Device is locked - that is OK. What exact is now your question ?!?
Simply De-Activate the Connection, and you could change the Settings for this NET.

You need to select the used Hardware (PCAN-USB)
At the Moment you have select in the Sample GUI a ISA Card ... ?!?
Please read also the documentation and some Tutorials how CAN Bus work. That will help you very much later on when you write your own Software.
