Woodward Custom ISO15765

Description

The information present in the DID definition structure informs the code generator how to efficiently pack the bytes when the DID/PID is requested via the ISO15765 protocol.

The proper format of the structure is defined in the "example" PID file (iso15765_4_pid_example). The block displays a table with all of the individual fields and the respective properties.

There is a PID database of officially supported PIDs for MODE 1. There is a file in the distribution that contains the definitions for these PIDs (woodward_custom_iso15765_pid_database). If there is a desire to override the default settings, the user may create their own file using the DID format.
