I understand, what I want is to be able to modify the value to count by means of a keyboard 4x4 and a lcd for not having to reprogram every time that the wants to modify the I number from maximum pulses to count.

For example: to show in a lcd

Push buttom RB0 to increase the value to count
Push buttom RB1 to diminish the value to count
Push buttom RB3 enter to record the value

Thanks

If you want, post your question in your language, probably someone else here can give us a hand and translate to english.

I just know english(a few) and French. i'm really sorry Leonardo
