Valant Posted April 4, 2008 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.
stryd_one Posted April 4, 2008 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 :)
