Hallo,
danke galli
weist du mit welchem K-Line Protokoll da gesprochen wird ?
http://www.onboarddiagnostics.com/page03.htm#ISO
Ich vermute dieses ###KWP2000### (Asynchronous serial communication up to 10.4 Kbaud)
SO 14230 KWP2000 (Asynchronous serial communication up to 10.4 Kbaud)
Pin 7: K-line bidirectional for communication
Pin 15: L-line (optional) unidirectional for waking up the ECU
Idle signal levels are high
Signals are active pull-down to 0V (0.00 to 2.40)
High signal voltage level: +12V (min/max 9.60 to 13.5)
Message may contain up to 255 bytes in the data field
Bit Timing;
UART signaling up to 10.4K baud, 8 data bits, no parity, 1 stop
