BenchChapter 4: Stars and hubs

B12WICK

The task

P0 drives the lamp through R1. Any value but 0 lights it.

P1 ticks every 16 cycles. The lamp should flare for one tick.

Then leave it dark for three ticks, and repeat.

The chip's ports, each with its kind and the parts its signal reaches. Cyan reads, lemon writes.

The output holds its level while you sleep, so one OUT covers several ticks.

Each hint goes a step further than the one before. Open them one at a time.

Hint 1Show

Sleep, write 1, sleep once, write 0, then sleep three times before the next flare.

Hint 2Show

A chip asleep on IN P1 spends no energy. The dark stretches are just more sleeps.
