7-SEGMENT LCD

wow

After much optimization, I got the cost down to 10! This took some serious effort and a brute force search to find some magic numbers: 10/311/15

Optimizing power a little gave me 17/233/11. Have not yet optimized lines of code.

First try: 17 / 339 / 17

Very nice, just 14, but 400+ and 25 lines, think missing something, solved with ROM decoder but somehow uneffective

14/231/11

And I don't know how to solve in less than 10 lines of code

more importantly, this puzzle helped me FINALLY figure out how to get two modules to play nicely on a shared blocking input bus

¥14 / 274 / 13 (that's my first solution, slightly optimised)

Great puzzle.

14 / 239 / 11

14 cost, 248 power, 12 lines (in a single design)
Nice puzzle, lots of possible solutions, lots of room for optimization

I know this has been a while but the fact is digital signals canNOT be listened to by every connected chip as a digital signal has an address bit attached which tells all but the destination chip to ignore the signal. It's like listening to a radio; only one station comes through despite the many, many stations passing by.
