Description
Subject: Pixel printer
From: David 戴维 P. Solomon <daiwei@longteng-co-ltd.gd.cn>

We've been selected again for another project for the Shenzhen science fair. They want us to create a wirelessly controlled printer that accepts templates for 7x7 pixel matrices and prints them. 7x7 is the perfect size, it will allow little kids to print Space Invaders and stuff like that!

---------

Small hint: Control the bell, push, and motor outputs independently.

Big hint: Only one data packet comes from the radio during each test run, therefore you can read any portion of it during any time unit.

Optimization tip: Have a special 'router' microcontroller that operates on command sequences to read the data from the radio receiver.

In the verification-tab, the 'dispenser' is 1 cycle too early. So instead of writing to positions 7,9,15 ... - it writes to 6,8,14 . . .
It behaves as if the matrix went from 1 to 49 instead of 0 to 48
