Hi there, >>I've just an other question. Does your layout support a negative >>contrast voltage? I've a display which needs a negative contrast >> voltage... Really? A HD44780 Display with *negative* contrast voltage? Never seen this... anyway, there are very small DC/DC converters which can produce -5V (or even -12V) out of +5V. Look for "RO-0505S", Conrad sells them for about 8=80 bye, Michael --=20 Michael Reinelt <re...@eu...> http://home.pages.at/reinelt GPG-Key 0xDF13BA50 ICQ #288386781 |
