Hi

Not got access to FC just now to see your chart and I'm unsure how you are multiplexing but perhaps when in the macro that is adjusting the digit you could pulse the common pin?

Maybe something along the lines of using "x" as the variable to control the output pin, being 0 or 1.

Set an interrupt on a timer say for 600mS (or whatever) enabled when in the required macro, disabled when leaving. In the ISR have a calculation.

x = ! x (x = not x, changing between values every 600mS)

In your multiplex, check the value of x when it comes time to refresh the digit of interest and if 0 don't refresh.

Just a thought and without access to the chart I'm unsure how practical it may be.

Gracias por la respuesta, me ha servido de mucho.
He implementado unas condiciones dentro de la rutina de multiplexado que se cumplen cada cierto tiempo dado por el TMR1.
En concreto han sido 3 una para las centenas, otra para las decenas y otra para las unidades.
Ahora todo funciona bien.

I have the project finished and tested working perfectly.
But I wanted to make a modification by adding a new interruption but it won't let me select the type of interruption to insert (TMR1)
What could it be due to?

Hi

I have just added in "Main", an Interrupt Icon and could select Tmr1. This then compiled without issue.

You have many macros in your chart and it isn't possible to go through every one, so if you could be more specific as to where you are placing, maybe that would help narrow it down.

Your chip also has a Timer0 and Timer2 interrupts. Could they help?

Gracias por la respuesta.
Quería añadirlo dentro del main, justo detrás de la interrupción delRB0.
Se abre la ventana de configuración pero no me permite elegir ningún tipo de interrupción.

I closed Flowcode completely and when I run it again it works fine again.
I don't know what could have happened.
Thank you for taking the trouble to review it.
