K8035 exteriors impulsion count and decount

Hi,

I past time looking for a counter which can count and decount on the fly, by a simple push bouton.

The pulse are exterior pulse, the pulse have same V.

For example, I have to count 150 impulsions , push a button, and decount the 150 impulsions… all the impulsion are exterior.

So on the K8035 Kit, is there a mean to set the external impulsions to addition count, and to set to negative impulsion count?

Thanks for your answer.

Nota: I know, the keyboard can set manually up and down…but for exterior signal???

So On the assembly manual, I can switch the input between the born 8 and 9 on the connection… to send the impulsion on positive count/up or negative count/down.

But switching on the fly, Is there a risk to “reset” the memoy count?

I think no, as it is like pushing the down push button… but I ask before doing this.

Thank for your answer.

No, you can change from counting up/down, “on the fly”

So the Kit does the job, exterior impulse from a tripmaster, and changing count/decount “on the fly”…

and use the E.out, to sending the information to relay.

Unfortunately, Insering the kit in a box , I make a wrong thing, Since the auto control display “ERR 2” which means a keyboard error…

I think the PIC has a trouble…

For your information, the dipswitch in wrong position, make a “err3”.

Curiously in my system , I test the modulo 60 with inboard oscillator… is this as it was a chrono? because on my kit there is nothing on display (juste the “0000”) as I push a button.

If I need a new PIC to repare my kit, what is the procedure to keep it?

Thank for your answer.

Check the keyboard lines. It displays an error when the buttons are pressed at power-up.
If the unit has been configured as ‘modulo-60’, the unit will count seconds and minutes or minutes and hours as long as the button is pushed.
