Hi all, just wanted to know if there was a chip or something which would allow me to press a key to write a certain letter on the seven-segment display. I already know about a binary decoder which converts binary to decimal and then on to the seven-segment display (I believe this is the 4026).
I realise that that you would need 26 input pins for each letter, and think it is highly improbable, but if you know of such a thing, a reply would be greatly appreciated.
Thank you.
