This project is also a sister project to the J2534-pic project

J2534-pic:-URL

• Add more CAN OBD logic,
• remap SWD to GPIO for CAN chip mute control
• rev eng K-line etc (Prob similar to ELM327 schematics)
• add pictures of internals/mods and current menus
• add schematics in pdf format
• Add protocols for :-
  • 1 SAE J1850 PWM (41.6 kbaud)
  • 2 SAE J1850 VPW (10.4 kbaud)
  • 3 ISO 9141-2 (5 baud init, 10.4 kbaud)
  • 4 ISO 14230-4 KWP (5 baud init, 10.4 kbaud)
  • 5 ISO 14230-4 KWP (fast init, 10.4 kbaud)
  • 6 ISO 15765-4 CAN (11 bit ID, 500 kbaud)
  • 7 ISO 15765-4 CAN (29 bit ID, 500 kbaud)
  • 8 ISO 15765-4 CAN (11 bit ID, 250 kbaud)
  • 9 ISO 15765-4 CAN (29 bit ID, 250 kbaud)
• EEPROM saving, CAN Sniffer.
