QUESTION
This Code shows an growing up Intervaltimer. I'm using setInterval for it, but i don't know how to stop ist.
There is a funktion called ende(). Can i stop the Intervaltimer with this funktion?
The Reason to stop it is that when i hit the button(at the bottom) again then a second Timer starts. I don't know how to say it, test it out.
...ANSWER
Answered 2020-Jun-07 at 12:28Store the interval in a variable, then use that variable to stop the interval. However, since you are starting the interval inside a function and stopping it inside another function, you need to use a global variable. First declare a global variable x:
QUESTION
Im super new with VHDL and I have an assigned project to do. Basically what I'm aiming is to display 2 numbers and substract and add them with the help of a switch. (On FPGA Board)
For example: Assume I have a signal A with the bit value 9 and B with 2, whenever I open the switch it will operate A-B and display 7. The problem is, when I close the switch, I get 9 instead of 7. (It doesn't hold the value) What I want is to display all the substraction results with opening and closing the same switch : 9,7,5,3,1
What I did so far:
- I coded a decoder for the seven segment display
- I have a 5 bit bitslice adder substractor implementation
- In my main module, I have them as components and instantiations
- In main module, I have signals for the two numbers which I declared as the input values of my bitslice instantiatons
- In the process, I assigned the default values to my signals (9 and 2)
- Inside of an if statement, I assigned the signal A to the result signal (which is assigned to adder-substractor instantiations bit by bit) And assigned the signal for seven segment to result.
It works when I open the switch, but when I close the switch default value holds. How can I update the value of A with the result each time?
My Code:

Answered 2019-Nov-23 at 20:37The problem is in your game logic process. Since your HP and ATK signals are in the top level of the process, they essentially get a continuous assignment to the default values all the time. The only time this changes is when you open the switch and you see the expected result displayed. When you close the switch again, the values get assigned their defaults again, rather than retaining the previous arithmetic result.
If you assign those signals their defaults only when you trigger StartGameSwitch
(see below), then you should see the correct display when using your switch.
On a side note, your process sensitivity list was incomplete. The logic in your process depends on the switch signal S
, so this should be included in the sensitivity list (as I've shown below). It doesn't really matter for synthesis, only for correctly simulating your code.
