timing
01/01/70 00:00
delays aren't necessary if you monitor busy
01/01/70 00:00
Pullup resistors on P0
01/01/70 00:00
already answered
01/01/70 00:00
make sure
01/01/70 00:00
Is there any test procedure to test LCD Module?
01/01/70 00:00
from the shop
01/01/70 00:00
did you try...
01/01/70 00:00

lcd testing
01/01/70 00:00
Couple of links
01/01/70 00:00
no datasheet
01/01/70 00:00
Should work the same...
01/01/70 00:00
+1 for this answer

LJMP limits
01/01/70 00:00
delays aren't necessary if you monitor busy
01/01/70 00:00
May be LCD is damaged!!
01/01/70 00:00
Pin 3 may require a negative voltage
01/01/70 00:00
PLEASE!!!!
01/01/70 00:00
There is a "convention"
01/01/70 00:00
to clarify?
01/01/70 00:00
two problems with the 'advice' you followed
01/01/70 00:00
Only lower line of LCD is showing!
01/01/70 00:00
looks like pretty normal behavior to me ...
01/01/70 00:00
'cheap' -5 for a LCD
01/01/70 00:00
where is that standard?
01/01/70 00:00
It's not an EIA or a DIN standard ...
01/01/70 00:00
you said exactly that
01/01/70 00:00
We've all told him to read his LCD datasheet
01/01/70 00:00
this is getting ridiculous.
01/01/70 00:00
ok, I deserve -1 from before
01/01/70 00:00
why not spell it correctly
01/01/70 00:00
That's why there are datasheets
01/01/70 00:00
LCD is workingggg!!!!!!
01/01/70 00:00
Now get to work
01/01/70 00:00
MISTAKES made
01/01/70 00:00
Datasheet, which created a problem.
01/01/70 00:00
Can LCD datasheet be uploaded for others referen.?
01/01/70 00:00
You have to get the correct datasheet
01/01/70 00:00
need lcd testing procedure
01/01/70 00:00
You need more data!
01/01/70 00:00
addendum to Richards post
01/01/70 00:00
There is a de-facto standard

01/01/70 00:00
problem with second line of lcd
01/01/70 00:00
program
01/01/70 00:00
your code has a problem?
01/01/70 00:00
looks like experimenting again ...
01/01/70 00:00
from hitachi data sheet on HD44780
01/01/70 00:00
I'm starting to hate these datasheets
01/01/70 00:00
BULL
01/01/70 00:00
get it RIGHT before you deviate from spec's
01/01/70 00:00
OK... I give up...

01/01/70 00:00
program i used
01/01/70 00:00
driving voltage
01/01/70 00:00
its not the contrast problem
01/01/70 00:00
why?
01/01/70 00:00
Contrast and Initialization
01/01/70 00:00
you are, I hope, aware
01/01/70 00:00
That's the one...thanks
01/01/70 00:00
about P0
01/01/70 00:00
It shows that you "experiment" instead of reading
01/01/70 00:00
gibberish
01/01/70 00:00
small correction
01/01/70 00:00
thanks a lot
