Hi, I have designed a watch using 3 counter stages with D flip flops. I want to eventually build this thing in real life. My question is about 7 segment displays, or really the decoders/drivers for them.
The decoders we use for seven seg displays cause the displays to show 0-F in hex when 0000-1111 are applied to it. Now since I am making a watch I want something a little different.
I have 6 D flip flop outputs which represent seconds, and 6 more which represent minutes. We won't talk about hours for now, I will deal with that later.
So the 7 seg display decoders have to take in a 6 bit binary value and show 0-60, while ignoring 61-63. Obviously you need two 7 seg displays for this, and each one must behave differently. One of them will show 0-6, and the other 0-9. So thats probably two decoders right there, one for each. The minutes portion is exactly the same.
Now its very easy to design a decoder that does this myself, but the amount of wires and gates necessary would be crazy. My question is, are there already such decoders for 7 seg displays out there that I can buy?
Thank you
