# Keypad Decoder

A simple project for Tiny Tapeout 6 submission.

It scannes the attached keypad for a pressed key, and when detected, displays
the pressed key on the 7-segment display. There are no debouncing, latching,
buffering, or anything advanced.

The idea for key scanning stage is probably similar to the one used in the
standard ICs like: 74C922, ADP5586, or LM8330. 

To try the simulation, after clicking the green play button, click the reset
button, and then start pressing and releasing the keys on the keypad, or your
computer keyboard. The eqivalent numbers and keys should be displyed on the
7-segment display.
