Programmable device

Hey,

Don't know if it's the right place for this but...
I'm looking for a device with a small screen and buttons like a simple cellular phone i can program.
I have no idea where to start looking for such device.
Any help would be appreciated.
Cheers

Re: Programmable device

I want code some menus for the device and make it do some minor calculations.
i need it to have some numbers and letters because the users will have to enter some info oh and some directional buttons too so they can browse the menus.

Thanks

Re: Programmable device

Hi
Your situation is very famous and widely used almost in every application. You need two modules for your requirments:
1- For calculations, you need ither microcontroller or DSP. But I think you don't need to make alot of calculations so you should use microcontroller. The major three companies for microcontrollers are "ATMEl, Freescale & MicroChip".

2 - For the display you need screen either " Graphical LCD" or "Dot Matrix LCD". Dot matrix LCDs are easier to use and they can display any character usig 5X8 Dots per charachter.

The question now what should you do? Simply, you need to buy a board containg a controller and an LCD. This is very easy to find but not so cheap. However, The board is very immportant and helpful to develop prototypes for alot of projects .

For example, see the following board and you can buy it from Digi-Key.com
