Character LCDs / NHD-0240A2 Can't write to location 30 in either row
« on: June 28, 2017, 09:42:27 AM »
I have a 2 row 40 character display and I don't know what's going on here but I can't write a single character to location 30 in either row 1 or 2 addresses 9F & DF.  I can write strings of characters but not one character at a time to those locations.  I can write single characters to other addresses but not those two.  I have another NH display that I tried and I have the same problem with that display also.

Any Ideas, Thank You
