Pic Serial LCD - YokYokBloomBloomBakaBaka - holopoint.rm - Jun 12 7:39:00 2003


Hello all.

I want to make a serial LCD controller using a pic16F628
Can someone help me with some schematics and code samples ?
This is my first PIC projects. Well, second, the first was a
magnificent led blinker.

Thanks,
Shash.

PS. You can ignore the YokYokBloomBloomBakaBaka in the subject.
Just to grab your attention. :)

Does the PIC have 2 free lines to accept serial commands from a PC or
another PIC ? Does the current code support this ?
Thanks,
Shash.

Hi,

The 16F84A has enough ports for the full 8 bit LCD, one incoming
serial, and RA4 is spare although not the 'easiest' port to work with for
outputs, I'm also learning !!!
I changed this code to use some serial utilities I found to run at
19,200 rather than 2400/9600, the code for this LCD only has 'incoming'
serial, I found some excellent macros for both LCD and RS232 on the PICList
site, just can't remember exactly where !!.
The Cheapic tutorials on
http://www.piclist.com/techref/piclist/cheapic/index.htm taught me a great
deal about the PIC, RS232 and LCD.

Is this code available on your site ?
if not, could you send it to me ? (Holopoint-AT-rocketmail-DOT-com)
Which PIC pin in the serial input ?
Thanks,
Shash.

Hi,

Now I check that was the first one I tried,
http://www.mindspring.com/~tcoonan/lcd.html was the one I used and changed
to 19,200, a mod was also needed to the VB prog supplied (inc source) on
this site to support 19,200. My circuit was the same as here although I
omitted the two jumpers as my display was two lines and I fixed the baud
rate at 19,200.

I will send the asm's but note my circuit included a MAX233 on the
serial port so the usual 'reversed bits' of serial doesn't apply, you will
see the commented out lines in the code, my circuit also uses a 4Mhz crystal
for XT_OSC.

I don't want to take any credit for this code as most of it is from
the site above with a 'chopped' serial utilities I also got.

Cheers
