Real time clock ICs

[Eng4444]

i wonder how i was told that:

" Since my original program was configured for a 4-Line LCD (which extensively used the LCDOut command), and you're using a 2-Line LCD which does not, unless you make significant changes to the program to compensate for the difference it's not exactly going to work, is it? "

++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++

But if somehow someone focused on what i was saying it would have been nicer..i'm not asking to just receive any answers...

i was talking about the program located at:

http://www.melabs.com/resources/samp...ted/MN1307.txt

there, it is written that:
"
' Written for 2 line 16 Character LCD
"

and i tried it like this but with a PIC16F628A and didn't work.

This is why i will ask again if i should do some changes to the program; and what are they?

thank you.

Hi,

I think Melanie in her remarks in her program was reffering to a LCD with 2 rows and 16 characters on each row (2*16 LCD). Melanie usually uses as little special hardware as possible so she probably just pulled up the most common LCD from her magic drawer. This LCD is electrically connected to the PIC using 4 data lines (and some more) which are mentioned in the LCDOUT command.

If you have 2 cables to the LCD (plus power) is is probably a serial LCD which can not be used using the LCDOUT command.

Hard to tell without haveing the schematics and really understanding what you whish to do.

i can have any LCD i want. This is not a problem.

now i have 2:
Winstar WH1602A ( 2 lines, 16 char) and WINSTAR WH160A (4 x 16).

and they are both parallel as i think... right? to assure you, check:

winstar.com.tw

so this is the 2 lines 16 char LCD i used and the program didn't work.

Still again asking: should i change something related to PIC16F628A?

thank you.
