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:
Code: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
Awesome!!!!!!!!
Bug of setting hours (23-->0) solved :
andCode:' 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
This is it ! Best regards !Code:' 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
Just connect RD7 to matrix and having 8 columns instead 7 :). No software update required.Attachment 6076
Soft update : if hour < 10 then not show first 0.
Code: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
I use 4k7 pullup resistors on the I2C bus, as i read somewhere that its a bit fussy with 10K....dont know how true this is
Now I intend to use two 5x7 led matrix, since some ports of PIC (16F877A) are free...
Please, I need help : how can making scroll in this case ?
Note : PortB are lines (7) ; PortC are columns from 0 to 7 ; PortD are columns from 8 to 15.
I found a way...but I think it's not the BETTER way :(.
LED's on column 7 (PortD 0) are, sometimes, on ... What @##%$@ is this ?Code:'
' Display RTC & temp.
' -----------
LOOPing:
FOR scroll = 0 TO 70
FOR scan = 0 TO 7
PORTB=%11111111
PAUSE 1
PORTc = 1
PORTd = 1
FOR counter = 0 TO 15
PORTB = leddata [counter]
pause 1
if counter > 7 then
PORTD = PORTD * 2
else
portc = portc * 2
endif
NEXT
NEXT
FOR counter = 0 TO 70
leddata [counter] = leddata [counter+1]
NEXT
NEXT
Thanks for making this an article!

My first working variant of scroll-thermo-clock : http://www.youtube.com/watch?v=Zkv4EbElOCg
Used : 16F877A, DS1307, home-made LED's matrix (7x7) and DS18B20 (missing in video, don't have anyone :( ).
Different code from previous example (because of my custom matrix). Enjoy !
There was a problem with the web site when the article was first published. It appears to be fixed now.
Thanks Dan for re-posting the article.

what are the values of X1 and X2,?Quote:

thanks lot for the fast reply n giving all instructions to build this without hiding..
by the way ur final video shows 0.0 c because missing of thermo saensor??
can u upload a new video with full functionality..?
