This protocol decoder is heavily based and tested on dumps from Jeep ZJ '98.

It's alive because:

• First inspiration: http:https://www.kolumbus.fi/juha.niinikoski/CCD_bus/ccd_display.htm
• Great datasheet for CDP68HC68S1
• Some Chrysler's US patents (for example 4,706,082)
• Great summary of everything in one place: http:https://www.cnblogs.com/shangdawei/p/3570499.html
• Forum topic at: http:https://thespeedfreaks.net/showthread.php?12585-CCDuino-A-ZJ-Databus-Project/ (no longer available)
• Another CCD project: https://chryslerccdsci.wordpress.com/
• Projects from https://github.com/xerootg/
• Google Sheet with data: https://docs.google.com/spreadsheets/d/1-7Ahhgu7fPNAfORWXrjADwHnI8PiozMbrc1AF3RrglQ
• Opendbc's dbc file for Jeep ZJ: https://github.com/csouers/opendbc/blob/master/1998_jeep_grand_cherokee_59limited.dbc

and of course because of great extendable logic analyzer: https://sigrok.org/

Just copy ccd/ directory to place where all protocol decoders from Sigrok are. On Linux, it's enough to copy it to local directory: $HOME/.local/share/libsigrokdecode/decoders/
