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
