- Clock: 1 Hz
How it works
This is a simple 8-bit counter with a display showing counter 16 value. The input switches set the reset value of the counter. Counter reset is synchronous. The lower 4 bits of the counter value is converted to the symbol for 7 segment display. Will be improved in the future.
How to test
Set the input switches to value 0 (all off). Reset the device, set the clock to 1 Hz. Each second the 7 segment display should show a new symbol from "0" to "F".
Set the input switches to value 11. Reset the device. Send one clock pulse, the display should show 'b'. Enable 1 Hz clock, the display will continue showing hex numbers starting from 'b';
