I am designing a new project, and would like to use a Glcd for the display.
I do not need something real high end, The meter that the Glcd will replace measures 3 1/4" X 1 1/2"
While I can cur the opening larger if need be.
1) What do I look for in just the basic display?
2) Do I need a separate processor just for the display?
3) Is the a series 16 or 18xxx pic that would handle it all?
Right now I need 7 input pins for switches, and 3 outputs for relays, and leds.
Will also need what ever I/O pins that the Glcd would require.

Re: Glcd basic needs
Hello Bob,
Really depends on what you need, eg colour or monochrome, pixel resolution, size of pixels and most importantly the interface to the microcontroller.1) What do I look for in just the basic display?
No you should be able to control the display and your application using a single microcontroller.2) Do I need a separate processor just for the display?
Either would be fine for the application though the 18F range generally have more memory and some can run up to 48MHz (12MIPs).3) Is the a series 16 or 18xxx pic that would handle it all?

Re: Glcd basic needs
Ben,
Thanks.
Will have to look around and see what I can find for a display. I have a couple spare 16F1827 chips but think I may need a few more IO pins unless I multiplex a few of the switch inputs. Just waiting for the codes for my FC 5.0 upgrade as we speak. Will document this one better than my last so I can put it in the projects section of the forum.

Re: Glcd basic needs
David,
Thanks. I contacted Microcontroller shop by phone today, they said I should have my download link and activation code by morning my time in the states.
I can wait, still in the planning stages, and need to get some electronic parts still. Would like to try and source them all from Mouser again. I did find one glcd with a RGB background I like but it was 3 volt and a serial. Parallel is easier I think.
Did manage to get the simulator to print some text, will try for a circle tomorrow. Think I will need some graph paper to help figure out the coordinates first.
