Character LCDs / Conflicting datasheets???
« on: April 01, 2015, 05:05:57 PM »
Hello, I have both a NHD-0208BZ-RN-YBW-33V and a NHD-0208BZ-FSW-GBW-33V3. I am using them in 4-bit mode. The NHD-0208BZ-FSW-GBW-33V3 datasheet says to pull the unused pins low, but the NHD-0208BZ-RN-YBW-33V datasheet says no connect. I can only write to either screen when the pins are pulled low. Is this a known issue? I have found conflicting information for similar modules on weather or not these pins should be grounded or not.
