I have coded a little routine to operate a LCD (16x2 HD44780U) through
a 8051 (at89s51) micro-controller and I haven't tested it yet, but I'm
afraid that it won't work properly.

Besides watching the busy flag signal of the LCD is there any other
preocupation about timings? Or checking other pins?

In the code below, is it possible to "jb" directly a pin like p1.7? The
assembler (asem51) doesn't complain but I'm not sure.

Yes you can do jb p1.7, it jumps if the pin is high

Depending on the speed you are running the micro at, your program may
not work as it may be too fast for the display. They are quite slow old
things. You might have to put in some "nop" (no operation) commands in
between setting enable pins and setting data bus values.

I regret that's beyond my powers! There's an election due next spring,
probably. Then we'll see what the 'great unwashed' make of his record.

And "unwashed" is what they'll be if you contract to Halliburton for

I don't know. What does the data sheet say?

Have you ever tried to read a Hitachi LCD controller data sheet? They

are very badly translated and difficult to understand. Somewhere on the
web, I can't remember where, someone has done an interpretation job on
it.

Frhtiof,

By responding the way you have, you exemplify the aggravating ignorance
and arrogance that refuses to accept you are unqualified to make
reasonable decisions-

Glad to be of service - I am also "unqualified" to vote in the U.S.

That is just the point! If you had taken to time to read the site,

Mo makes a thing she calls a Big Danish Baby. Lots of butter in a

expands, and the edges sort of curl over and get brown, so it becomes
a sort of big floppy pancake/crepe thing. We also serve that with
powdered sugar, berries, and maybe whipped cream. It's pretty good.
I'll post her recipe if you'll post yours.

Sounds like a big popover - Yum

Right- everyone has their rationalizations. The Bush administration is
now up to 23 after the fact rationalizations for the invasion of Iraq.

Only 23? If only they would reveal the real reason. I suppose it would be a
fools hope on my part that if the Pres came right out and admitted that we
invaded Iraq because he had a personal hatred of Saddam and wanted to stick hot
rods into his balls, that might change the minds of a few of his supporters?

I understood your comment and found it quite clever.

However it may not be true, the Bush Admins counter is that they have increased
spending on R&D 44%, and not decreased it. I can't comment on if that is true,
or if it is true if that represents a lot of investement in military, and
voodoo pseudo science. My moneys on the Lauretes and not the Bush Admin for
telling the truth.

I think I've noticed a trend in here. righties generally agree with righties
regardless of how extreme their positions are, at least they don't bother to
post to complain.

But us lefties, we are always picking on each other, disagreeing with each
other, and trying to change each others minds. OK, I admitt to letting some
pass, too.

I can't tell who wrote this>> The >>GSM Codecs work by building a model of
the human "speech machinery",
determining the model parameters and the initial stimulus parameter and
then
send the parameter set across; not the actual data: The voice at the
recieving end is merely a simulation of the speaker! The Codecs are
speech-only!!

It is a pretty good simulation, since one can normally recognise the voice
of the caller.

Yes, I've always found this facinating and hope to have time to explore this

someday. It shows what kinds of miracles are possible when you can live in the
universe of the lossy!

Regarding the topic here I wonder what would be the most popular cheap

everything.

And did that suck too ;-)

The original triple-diffused 3055's were nice parts; good betas at
high currents and very rugged. Later on, people started using cheaper
epitaxial chips half the size, and things went to hell.

on GSM voice, Morse might
be be the best!

Or DTMF, that way you can receive with a normal modern modem. Still it would be
a interesting race, DTMF vs. Morse. I've done DTMF over voice on all the types
of digital cell phones, not bad if you can live with slow.

Which, translated into American, comes out "you disagree with Fred, so

I did not neccessarily *disagree* - it's just that I think that even a
Nobel Prize Winners opinion is just an Opinion .... and that in any case it
is an itellectual and elitist argumentation, who will not cut much ice with
convincing the majority of the voters - which is what an election is about.
Merely being right is a loosing position!

That's much more uncertain. You know his position, but you can't be sure

Hi Frithiof Andreas,

I cannot tell since I have not yet used the two 500 pcs bags of BC547/BC557
I bought for total amont of about USD 7. some time ago. I only *needed* 10
of each flavour - but - the hobbyist bags of 25's were priced at USD 3.
Each!!!


Just be careful with those. When transistors sell for under a cent a

piece in quantities under half a million or so they sometimes come from
rather obscure sources. Meaning that the spec may be kinda loose.
