Strange LCD Issue


Valant

Recommended Posts

Hey guys.

I put together a test cable to make sure my LCD works.  It's connected to my computer's parallel port and draws 5 volts from the power supply.  Suppose I want to write "ABC D" to it.  The screen shows, "AABBCC  DD."  What could be wrong?  I've double checked my wiring, and it's all where it should be...

My LCD's a backlit HD44780, 16x2, 8-bit.
