Hey guys, I am experiencing a bit of a problem with my MTC-40400x 4x40 lcd. I ran it through the lpt port and was very happy that I got the test signal...or I got the module to actually power on and the contrast control showed all the blocks to be there.
When I put data into the top two lines it came up, but not in the lower two lines. I have since then used a multimeter to test the connection of the E2 line (*connected to lpt pin 14), it showed no resistence. I've tried the alternate addressing option on smartie...nothing. I have run out of ideas and want to know what you think.
