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 longcan 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 :

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! jay

You might look at our SLCD board at

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