Scrolling thermo

[cncmachineguy]

Do you mean how do you display 4 digits on an 8x8 display without scrolling? That I don't think you can do and still be able to read it.

Maybe I just don't understand the question

Sorry for my poor english...
So, If set tens hour : on matrix appears (without scrolling) tens hour digit only.
If set hour : on matrix appears (without scrolling) hour digit only.
etc, etc.
Otherwise I can't setting the clock, because I don't see what happens ...

I DID IT !
Full working () version of scroll-thermo-clock, using PIC16F877A. With buttons for setting hours/minutes !
Enjoy !

LE : The answer on my previous question:

    portb=0
    portd=0
    pause 1
    FOR counter = 0 TO 4
        READ oraa*5+counter,leddata [counter]    
    NEXT 
        PORTB=%11111111
        PORTD = 1
        FOR counter = 0 TO 4
           PORTB = leddata [counter]       
           PORTD = PORTD * 2
        leddata [counter] = leddata [counter+1]
        NEXT

Bug of setting hours (23-->0) solved :

                '    Decrement Units Hours
                '    ---------------
        If CounterC=1 then
            if setdechour=2 then
              IF SetHour=0 THEN
                 SetHour= 3
                 else    
                 SetHour=SetHour-1
              Endif
            else
              if sethour=0 then
                sethour=9
                else
                sethour=sethour-1
              endif            
            endif
        endif

and

                '    Increment Units Hours
                '    ---------------
        If CounterC=1 then
            if SetDecHour=2  then
                if SetHour=3 then
                    SetHour=0
                else
                    SetHour=SetHour+1
                endif
             else
                if SetHour=9 then
                   SetHour=0
                else
                   SetHour=SetHour+1
                endif         
            Endif    
       endif

This is it ! Best regards !

Just connect RD7 to matrix and having 8 columns instead 7 . No software update required.

[fratello]

Soft update : if hour < 10 then not show first 0.

if oraa = 0 then
    FOR counter = 0 TO 4
    leddata [counter+41] = %11111111
    next
    else    
    FOR counter = 0 TO 4
        READ oraa*5+counter,leddata [counter+41]      'stores tens hours digit in leddata locations
    NEXT
endif
