Valant Posted April 4, 2008 Report Share Posted April 4, 2008 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. Quote Link to comment Share on other sites More sharing options...
stryd_one Posted April 4, 2008 Report Share Posted April 4, 2008 Well it seems that your PC isn't writing correctly to the LCD... You might as well hook it up to a core module and test it in the real-life environment it will be used in :) Quote Link to comment Share on other sites More sharing options...
