'[PIC]:"Hello World" on a 16f84 & HD44780-compatibl'

Check the piclist.com site - there is a complete 4/8-bit interface in HiTech C
for those LCD's that I did.

I don't know how to find it as the site is organized counter-intuitively (to me,
anyway).  You'd have to ask James Newton - he gave me the URL one time.

There is a bug in the posted code.  In the routine which writes a byte
(selecting 4/8 bit mode of course), there is an extra click on the E pin.  You
need to move that to inside the 8-bit #if portion.

My apologies.. I should have mentioned that I don't know assembly. Is there a
HiTech-C equivalent? I have MPLAB and PIC-Lite.

Why, are PICs against the law in Dallas?

Who you going to work for?  If Dallas or TI, maybe you can get them to do more
PICs in the app notes.

Since I'm moving to Dallas, TX in two weeks, and don't know if I
will ever come back to PIC development other than as a hobbyist,
I figure I'd share some of my code.

Attached are the routines I use for accessing the Hitachi chips,
in HiTech C.

Enjoy!

click on "PIC FAQ", that should be obvious.
Now you have a choice of:
- Beginners Checklist. Steps, tutorials,help, advice.
- Development tools / Programmers
- Instruction Set Reference
- Routines / Code library / Input/Output

isn't "Routines / Code library / Input/Output" the obvious choice? That gets
you to
- Input / Output
- Math / Functions / Conversions
- Conditionals / Program flow
- Time / Clocks / Delays
- Memory / Tables / Data
- Interrupts

and below that is a link to the C specific library, but lets say that you
miss that and go to "Input / Output" where the major categories are:
- Ports
- Peripherals
- Networks
- Data Link - Busses and Com Standards
- Physical layer - Analog Signal Generation and Detection

under "Peripherals" we find:
- Visual
- Audio
- Mechanical

and under "Visual" we find "PIC Specific LCD" which gets us a list like:
- matrix LCD driver
- 4-bit 8x2 Hitachi LCD driver
- PIC C Hitachi LCD Drivers by Andy Kunz
- Vee (negative supply) from PIC PWM by David Covick
and some links to other sites below that.

Now, how could anyone get lost there? If you went to the C Library, its the
same but there are a lot fewer entries... even easier. If you search the
site for "LCD" you get the generic LCD page which links to PIC Specific LCD
at the bottom.

Any suggestions for making it easier to find things on the site would be
very appreciated.

A very dynamic wireless design group is all I'm saying.

I don't know if PICs are against the law in Dallas.  Seems every
county in Texas has different laws on whether drinking beer is a
crime or not.  So, maybe PICs are friendly in Dallas, but Fort Worth
enacts a bounty in favour of the ARM processor...... (;>

I just meant that I don't think I'll have much time to do embedded
as my new role will be wireless hardware integration, which more
closely matches my training.

I'll still use PICS (perhaps to enter the Robot Wars... are you game,
Andy?) It's just that I've sold out as an independent contractor to
the highest bidded, and now have a competent team to spend my working
days with.  Have you heard of the Canadian Brain Drain?  To a Canadian
an increase in salary of over 100%, a drop in taxes of over 100%, and
cheaper health care premiums to boot.  You'ld have to be a mommas boy
to stay!!


Later,

Craig

Really?  Wow.  There's a big Motorola place right down the road from our
call center in Ft. Worth, I wonder if you'll meet anyone from there?

Hey, Jim, if you put a few "nav buttons" on the top of each
page, I'm sure AndyK would stop baiting you.  :)

*sigh*

two words.

contrast voltage.

i.e. 0V=dark
I knew it would be something as trivial as this, its downright embarrassing.

Thanks to everybody for your source code contributions, I'll be sure to look
them all over, as mine are rather rudimentary.

Regards, Tim

That would be 200%, silly.

100% means he pays 0 taxes.

That's good enough for me!  Where do I sign?
