Compiling Ultimaker 2+ Firmware

[killerb77 2]

I want to compile my own Ultimaker 2+ firmware.

 

It says this in the notes on github: “One time change: The UM2 made changes to the I2C driver. You will have to remove this driver function from the Arduino IDE by removing the TWI_vect interrupt routine in arduino/libraries/Wire/utility/twi.c, line 364 Note: when you compile the sources using the makefile you can skip this step.”

 

So do I just comment out or delete line 364 and that’s it?

I figured it out.  I had to delete or comment out the entire TWI_vect function.  I guess they were referencing about line 364.

I rewrote this line of the build instructions to be more clear.

Out of curiosity did you edit just the file "hardware\arduino\avr\libraries\Wire\src\utility\twi.c" as that's the only copy of twi.c I can find.

Old version v23 of arduino.  It's the version suggested in the instructions.
