Hi, I'm trying to use the LCD4Bit library with a very old display with a Hitachi HD44780A46 chip.
I tried the LCD4Bit because I heard it had greater compatibility with older displays. (I tried the LiquidCrystal library and could not get it to work either.)
It's been a long time since I have messed with this type of hardware so I'm a bit rusty.
I believe that I have everything connected properly, but the LCD had all of it's pixels turned on when I power up the Arduino and this never changes. Any ideas what I should try next?
Thanks in advance for any and all help!
(Forgot to mention I'm running the LCD4Bit example code. Didn't want to introduce any of my own bugs before getting it working. ;D)
