Clock on a 7-segment display with Сharliplexing

An example of using a 7 segment display with Charliplexing. The display controller is built without the use of a microcontroller.

After starting the simulation, the clock is in time correction mode. The [R] button resets the counters to zero and the indicator shows [00:00] . Using the buttons [Min+1], [Min+10], [Hour+1] set the current time and press the [SET] button. Pressing the [V] button increases the counting speed by 8 times.
