Hi all,
I've got a little project on my hands at the moment and I need a bit of help with the design. The overall project is a dice, it displays a random number between 1 and 6. The output of the random number circuit is a 3 bit code (A, B and C).
At the moment I'm going to represent say 6 with the binary value 110 (A=1 B=1 C=0)
I'm trying to design a combo logic circuit to drive a 7-segment display. The circuit I need to design is the decoder for the display.
So I've got my truth table...
**broken link removed**
(a-g are the display inputs - a logic 0 turns the relevant part of the display on)
Past this and I'm stumped
As in the topic title I have to keep this design to just NAND gates and inverters. Specifically the 74LS04 (inverter) and the 74LS00 (NAND)
Anyone got any ideas? :?:
