Issues compiling the program "error: unable to find a register to spill in class 'NO_REGS'" #15
Description
Hi, When I try to compile the example code (arcs_lcd) to the Arduino Nano I get the following errors, How do I resolve this issue?
More info! - So it looks to be an issue with the Arduino IDE version I am using which is 1.8.5. I have downloaded a copy of Arduino IDE 1.6.0 which seems to have resolved the issue with it compiling. Would it be possible if a patch could be issued to resolve the issue with version 1.8.5 or the IDE.
Best,
Oliver
