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.

Verdammte Heinz 2 Jul, 2023 @ 8:24am

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

Unchangeling 24 Jul, 2020 @ 1:04am

¥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

@CYBER
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.

how do you acces the ppuzzles?

sophie <3 25 Jan, 2019 @ 3:33am

how do i get to the puzzle

sophie <3 25 Jan, 2019 @ 3:25am

wow

sophie <3 25 Jan, 2019 @ 3:10am

How do you make puzzles? Do I have to advance in the game?

Xenofix 9 Oct, 2018 @ 5:50pm

Great puzzle!
I've optimized for cost and I'm down to 11 324 15.
Or with less lines for one yuan more: 12 301 13.

15/277/12.

I was able to cut out a test and only check against 2 for lighting f. With the help of an OR chip I can add 50 to everything else. -1 becomes 49 (not enough to activate OR gate) and 2 stays 2. The rest all become 50 or greater and activate the OR gate.

This was simple enough with treating keypad entries as two table entries for the DX300 chips. Made -1 easy to implement and I just had to set up two possible tests on what to send for segment F, as the two options for off are "-1" and "2."

@c00l sp0T, you're not listening to what I am saying.
In my original comment, I said I do not like how this game handles digital signals - irl a single signal can be detected and received by every capable chip that is connected within reason. You then (half a year later, I might add) start talking about analog and digital signals and how one is measured by voltage and the other by amperage (which is not true). Perhaps I could have used the simple I/O pin (it's not called P-Port), but that was not what I was talking about. Now you are just posting nonsense, the gate pin on a field-effect transistor (also not what I was talking about) only needs to be charged (positively or negatively depending on type) for electricity to flow. They are not a simple on/off switch in the way you seem to be describing them, they can also be partially open. How many volts you need to supply to the gate pin can also be looked up in datasheets. I suggest experimenting with real life electronics.

@Cyber
Not really. A p-doped Transistor needs 1/√2 Volts & ~50mA to switch from LOW to HIGH. So a transistor is a consumer. Its different to a Flip-Flop which works with the De Morgan's Law's and works just tough a logical flow controll. Use the P-Line instead and every device can listen to the same signal. I often use this as Clock Signal. Im also sure that the XBUS in Shenzhen is concepted to use it like pending Signals.

As I know is an analog signal just a 0%-100% (float 0.0-1.0) value from a specified constant from voltage and amperage.

CYBER 9 Apr, 2018 @ 4:06am

@c00L sp0T, sorry, but measuring volts or amps is nonsense. In reality, both analog and digital signals are about sending and measuring volts, with the difference being that analog devices can send any value while digital devices can only send a 'on' or 'off'. Unless you send data via a protocol like I2C, multiple connected devices can listen to the same signal, but that's not possible in Shenzhen I/O.

G4mm4g0bl1n 8 Apr, 2018 @ 5:01am

@Cyber
Because XBUS is a digital port and the P-Port is an analog port. The difference in reality is about meassuring the voltage or the amperage. When you measure the voltage can the voltage also be measured over the complete circuit, but when you measure amperage then you measure device is a consumer and this will drop the amperage over the complete circuit to 0. So use the P-Port instead, but think about that the P-Port can not send Data Cross-Over at the same Instruction Cycle.

CYBER 3 Nov, 2017 @ 10:15am

this made me hate the way Shenzhen I/O handles x-bus stuff, why can't I have multiple controllers receiving the same signal at the same time :'(
14-346-16 (I blame having to repeat the signal for the other controller)
very nice level btw :)
