v0.11.3

  • Remove embedded platform-specific code from generated signals file for firmware (to match vi-firmware v6.0.2).
  • Add documentation on installing in Windows without Cygwin.

v0.11.2

  • Fixed parsing of v6.x style OpenXC messages from a network data source.
  • Fixed use of const variables in generated code.
  • Fixed a code gen. regression where custom C++ functions were called before being declared / defined.
  • Include OBD2 message handler in generated code so it can be used as a handler without custom source code files.
  • Don't require a working network connection and DNS to run the test suite.

v0.11.1

  • Fixed receiving data from new network based VI using null delimiters
  • Make sure const variables are initialized in generated firmware code.

v0.11

  • Support communicating with vi-firmware v6.x.
  • Support generating code for vi-firmware v6.x.
  • Support control commands over serial in additional to USB (version, device ID diagnostics, raw CAN messages).
  • Read debug log data over USB from a VI (see the log-mode flag on the CLI tools).
  • Support diagnostic request/response exchange with a v6.x VI.
  • Add openxc-diag, openxc-scanner and openxc-obd2scanner CLI tools.
  • Increase Bluetooth VI connection reliabilty when sending commands.

v0.10.3

  • In generated code, include the extra sources after messages and signals so they are already defined.

v0.10.2
