The LIN Frame Format

In simple terms, the LIN bus message frame consists of a header and a response.
Typically, the LIN master transmits a header to the LIN bus. This triggers a slave, which sends up to 8 data bytes in response.

LIN Decoding in HScope

Use the following settings:

• Input range: at least 16V
• Sampling rate: at least 100KSa/s
• Use the digital module to enable the LIN decoding

Sample of HScope decoded data:

• In the HEADER part the module ID is in YELLOW color.
• Data fields are in GREEN color.
• Light BLUE fields are for parity and CRC control.

HScope LIN decoder performs automatically: LIN bus speed recognition, parity and CRC check. In case of problem the corresponding field will be in RED color:
