Wrong/missing chars

MORA · Post by **MORA** » March 7th, 2007, 5:39 pm

After a while (10secs to several minutes) I get wrong or missing chars on the display, if the line is updated often enough it goes away by itself, but if its fairly static the error remains untill the screen changes to next page.

Is there anyway to get smartie to reload the entire page at some interval to correct this ?

The display is a 4*20 LPT1

Why the characters should disappear?

I own a parallel connection LCD and its working flawless.

Please check your port settings.

Edit: check also for second instance of the program

simple workaround
Set two screens (enabled both) with the same lines, switching from one to other will solve this strange behaviour.

I am using the default LPT1 data, just tried setting timer multipiler, but didnt help, the 2 screen fix can work, but it complicated everything by having 2 screens for each static screen.

which version are you using?
can you check the latest beta as well the 5.3 final?

I am using 5.4 RC2, but used the latest stable before that with same problems.

I brought the lcd in a finished version, only mod I made myself is drawing the power from usb instead of molex.

Something is going on with your display...
try to modify the refresh interval to a higher rate

Even at 500ms update interval theres problems.
Sofar only with shifting chars, like MB becomes MMB or MBB for a sec.

this is my screen

Code: Select all

$Time(ddddd  hh:nn)
 CPU:$Right($CPUUsage%%,$3%) MEM:$Right($MemFreeMB,$5%)
C:$Right($HDFreg(C),$4%)GB of $Right($HDTotag(C),$3%)GB
Z:$Right($HDFreg(Z),$4%)GB of $Right($HDTotag(Z),$3%)GB

line 1,3,4 is center

Seems "Emulate LCD" helped, what does that function do ?

[Edit] After 15minutes the first char went missing and there were a few times with shifted chars.
Thats with emulate lcd, 1000ms update and 2 in timer multipiler

The emulate LCD function enables the virtual display to show exactly the LCD output (inclubing any custom characters).
