I'm testing 1.94 and 1.95. I got the LCD so I'm not as worried about serial, but I have another problem. My LCD displays garbage data with every refresh. Sometimes I'll catch a glimpses of an "mpg" or a "0.00" but that's it. I'm using an arduino Nano clone with the atmega328p, set up to use 4 bit parallel for the 16x2 LCD. The LCD works with other sketch examples so I know the wiring is fine, but I'm not sure what I'm missing. I had everything wired but I stripped it back to just the LCD stuff for testing. Do you have any thoughts about this?

I just went back and tested 1.93, and it works for the first two frames, but then becomes garbage also
Okay I found it!! Flaky power supply to the LCD caused the garbled data!
