PSA VAN-CAN protocol bridge: translating vehicle bus generations

PSA VAN-CAN protocol bridge converts vehicle messages from AEE2001 to AEE2004 or AEE2010, and from AEE2004 to AEE2010, so newer PSA head units and displays can work in older cars. Its ESP32 firmware handles VAN and CAN traffic, including steering controls, dashboard data and display messages. The repository documents VAN frame encoding, fields, checks and reply timing.
