VGA LCD WITH PIC ?

[Peter Kiproff]

I'm looking into the possibility of sending text at least a bit map of
characters to a LCD display

There are several 1/4 VGA LCD's also monitor LCD's, some of these are approx
6" or so long

can I drive them with a PIC or do I need to produce video with sync ect.

I used to use a Sieko LARGE char 16 * 1 LCD with LED backlight however these
are no longer available

so I'm looking for options if you can think of any.

Thanks for your input

One option that might be open to you or not. Circuit Cellar
magazine late last year had a very simple circuit with just
a few ttl counters that was enough to generate one of the vga
modes. You might see whether that circuit or the article
that went with it might give you some ideas or a solution.

Hi Peter,
You can have a look on my own "XY-plotter" article published in Circuit
Cellar (available online here :
http://www.circuitcellar.com/library/print/0903/lacoste-158/), it could be a
starting point...
Friendly yours,

You could interface the PIC to a 'generic' ISA VGA video card....it gets
real easy if you use an 8bitter but unless you've got a stash of 'old stuff'
or a local 'recycle depot', it might be a little harder to find these old
cards.
I've used 'super I/O ' cards to easily interface PICs to floppies, Hard
drives, extra RS-232 ports. And for some silly reason today someone dropped
off 4 'server' towers with 12 slot backplanes in them. makes it real nice to
test cards out!

Peter -

You might look at our SLCD board at www.reachtech.com. We have
customers using PICs to drive a 1/4 VGA display.

You may use one of our QVGA iLCD panels, you can use any (Windows
font and graphics (including animated graphics) loaded via the fre
setup software to the flash memory of the iLCD panel. Control can b
done via serial port or I2C even with a very low cost PIC then
