 		 #180329 - Re: There are two locations in the LCD
Responding to: ???'s previous message
Thanks for the info, Richard... but I was planning to copy the circuitry used in the PJRC experimenter board to drive the LCD. He seems to have worked it out pretty effectively by using one address line for RS, and another for R/W. (Low address to write data, high address to read...)

Thing is - I don't HAVE an oscilloscope to view the waveforms with.

I guess I could simply use the port pins to drive the signals directly... but it means writing my own code to drive the LCD, and I was hoping to use the compilers' built-in capabilities to handle that aspect of it.
