问题 I have got a small problem with my finite state machine which I have written in VHDL recently. I tried to create "intelligent" counter triggered by clock with frequency 2 Hz. This counter is built in one state of FSM and is started by pushing a button on DE2 board. Firstly, whole system is in IDLE state and if I push this button, state is changed to COUNTING and counter begin to be incremented and his current value is shown on LED display. After it reach value of modulo, the state COUNTING is
