Hello, everybody at HP tuners.com!
I see here is a lot of specialist in OBD-II at last. Would you help me? Nobody could before…
So… I design an ISO 14230 scanner based on AVR microcontroller programmed with C language. I've got started to understand the message flows. But I can not understand about synchronization the server (ECU) and client (tester). Where is the start -bit in front of each byte like RS232 link?
L-line would work for synchronization server and client, but it does not. About timing parameters… They very in big range and can not be used for synchronization.
Would you give me a tip about synchronization server (ECU) and client (tester)?
