1. ### Weird traffic controller

Cars and pedastrians are controlled by switch and we dont use latches. We create state machine and use vhdl to implement program in CPLD circuit. Hope that answer your questions.
2. ### Weird traffic controller

Hi, I got this instruction given: > For each of the following three scenarios, initially assume that the East-West traffic has had a green traffic light for a long time. 1) If a North-South car is detected then the traffic lights will cycle to green in that direction. The walk light will...
