Good Morning All,
I'm just starting my last year of uni and have been thinking about projects. What I'm trying to desing and make is a Counter Call system simalr to what you get a the post office/ super market cheese counter. With a twist that it can drive a regular large x2 7segment display aswell as have the possiblity of driving a TFT display! Eash display shows a number and is then incremented on the press of a button.
Having looked round at display drive IC's I came across the CH7017 from Chrontel. (http://www.chrontel.com/pdf/7017-7018ds.pdf) But this seems rather complex for what I'm wanting to do, it also appears to need a Graphics card input which I didnt want to have to use. I would like to make the counter system as basic as possible I had something like this in mind (http://www.doctronics.co.uk/4510.htm)
I'm not really sure if I'm heading in the right direction with this. Has anyone else come across a project like this? It would be great to hear from you if you have any ideas,
Many thanks
Rich

Thanks Mike
I was looking to use a Computer Type TFT probably no igger than 19 inches (or small flat screen TV's). It only really needs to display numbers 0 - 99.
The idea of the project is that it can give the end user the option of having a 7 segment display/Flip-Dot or a TV screen, depending on their budgets and trying to intergrate it in to one package. Its a flexiable project and at the moment its in its early stages. Its more than just an up counter because thats just too easy.
The BOB 2 products look good, they remind me of the text that comes up on the old video camcorders. Maybe there is a way to cannibalise one.
Thanks for the ideas
