HELLO,
Here's my problem:
i'd like to do a multiplication with PIC18F448 only, so i've two variabls X1 configured on PORTB 8bits & X2 configured on PORTC 4bits,
i've got to read whats on X1 & X2 first then do M=X1*X2; as 0*1, 0*....til 15*255 so i need 4 digit seven segments display maximum, on PORTA.
All i knw is
VAR X1,X2 : byte; M: word;
Begin
trisB:=0;
trisc:=0;
trisa:=0;
For x1:= 0 to 255 do
begin
For x2:= 0 to 15 do
begin
M:=x1*x2;
porta:=M; setbit(), delay_ms(1000); clearbit()// dont know how to configur this too
end;
end;
end.
i dnt knw how to decode all that for the 4 digits,,shoud i use
Function decode(M:word):word;
begin
if M:=o then decode:=$c0;
if M:=1 then decode:=$f9;
if M:=3225 then decode:=$0C99;
end;
but its toooo loo...ooong
All i've is a pic18F458 & 4digits seven segments display,,
Thanks in advance.

Hi,
Did you take a look at simple Seven Segment Display example from compiler:
...\mikroPascal PRO for PIC\Examples\Development Systems\EASYPIC7\Seven Segment Display
You can adjust the example for microcontroller that you use and test it on your hardware.
Best regards,
Marina

Hi,
In my previous answer I send you path in compiler where you can find the example.
There is no direct link for the example that I mentioned.
