Dear readers,

I am using a PIC16C622 in an optical-electrical (EO-)converter. To display
the value measured I use a Hitachi LM020XMBL, controlled by a HD44780
LCD-contoller. I want to transfer the data in a four-bit configuration at
the high nibble of port B of the pic.

There's an example of how to do this in the Microchip Embedded Control
Handbook, but to my opinion it should be much easier to do. I only have to
send ASCII-signs to the display (numbers 0 to 9 and the %-sign). On the
internet I can't find anything to my satisfaction too. Perhaps anyone else
has already interfaced this LCD-module to a PIC16C622. Please let me know

Thanks in advance,

Henk Renting
