Hi piclisters,

I have problems trying to make a "locate" in an Optrex LCD. The LCD has the
typicall Hitachi 77480 in it. It is 16char x 2lines, so I suppose the DDRAM
address for the 32 possible locations (without shift) are:

00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F
40 41 42 43 44 45 46 47 48 49 4A 4B 4C 4D 4E 4F

The "Set DDRAM Address" command seems to work OK for the last 15 char in
each line, but fails with addresses '00' and '40', apparently "hanging" the
44780. ÀAny ideas?

Note: the interface is 4-bits long, and the uC a 16C65

Thanks.
