Problem with Disp7sPort

Hello Thomas,

on my mega644 works it, but only with DDRC:=%00001111; .

Insert it after EnableInts;

Greetings
Harry

Hello!! Many many thanks for all the info and all the help!!!!!!!! You have a very good english!!!!

I have tried it and it´s better....now the two displays lights But display two act a little strange. I will try to attach a file showing how it looks like.

The program i´m running in the film is this code...

program Disp7s;

{ $NOSHADOW}
{ $W+ Warnings} {Warnings off}

Device = mega168;

Import SysTick, Disp7sPort;

From System Import ;

Define
ProcClock = 16000000; {Hertz}
SysTick = 10; {msec}
StackSize = $0020, iData;
FrameSize = $0020, iData;
Disp7sPort = PortC, nonmux;
DispDigits = 2, iData;
DispMode = shiftLeft;

begin
EnableInts;
DDRC:=%00001111;
mDelay(1000);
loop
for i:=10 to 20 do
write (DispOut, ByteToStr(i:2));
mDelay(1000);
endfor;
endloop;
end Disp7s.

Kindest regards

i don't know if this is relevant, but your stack and particularly your frame seems very small. The first digit looks OK, so I would certainly try doubling the frame and see if it makes a difference.

What happens when you're connect PortC,3 to RCK ?

Please check the connections from right display.

Try this:


instead of your for...next loop.

both display should now count synchron binary up. Segment A=2^0 ..... segment G=2^6 ..... decimal point=2^7

You have already installed resistors between ICs and displays ?
