I received a sample 116x12 VFD from Noritake, and wanted to try using it on my Arduino. However, after much troubleshooting I am unable to get it working.
I have used the sample code given on this site: http://www.noritake-elec.com/specification.php?id=Arduino_Noritake_VFD_GU7000&category=10&type=gu7000
I changed the appropriate values to match the display I am using, checked and double-checked the pin-outs, and still no luck displaying anything on it. The code compiles fine and appears to upload and run properly, but nothing shows up on the VFD.
A bit of odd behavior is that when I power the Arduino with a 9V 1A DC adapter, the VFD will very faintly glow orange, but nothing will be displayed.
I am drawing the 5V VCC from the Arduino +5V pin, because the VFD is supposed to only take about 260 mA of current total in use, and pulling from a 1A power source this should be no problem.
So I guess my question is, what am I doing wrong? Is the VFD bad, and how would I know if it is? I checked my Arduino after some testing to make sure I didn't burn it out or something accidentally, and it still works fine.
Thanks in advance for any help.
