Create an index with stateflow that only increments one at the time

Hi there,

Im trying to build a index with stateflow, but I want to increment only once when the input signal is high and again when it goes from low to high.

I have done this with blocks but now I want to use a stateflow chart.

Any suggestion?

Do I understand correctly that you want the logic:

• initial counter value 0
• if the initial value of the state is High, set the counter value to 1
• after that, increment the counter only when it goes from low to high ?

If so then the two first parts can be handled by initializing the counter to (initial state == high) and after that you just have an increment when going from low to high.

Do you have to worry about de-bouncing ?

Hi,

Thank you for your reply.

No, I dont need to worry about de-bouncing.

I think I got it... is bassically this, right?

Unfortunately I do not have enough experience to interpret that chart, but it does not look right to me.

I just divid the actions into two but it works the way I wanted.

Thank you for your help!
