I have read that my 2x16vfd display in my Silverstone LC03v case can be fixed if i can increase the latency for LCD Smartie. ( i end up with jumbled text after a period)
Also note that when my computer hung, the LCD Smartie ran perfectly over night. but once the PC was able to boot correctly i ended up with the garbled text again within an hour or two. I have also fitted magneto ferrite cores to eliminate any EMF interference.
Does anyone know how i can adjust this?
Our new official repo is on github

How can i increase the latency for LCD Smartie 5.4?

By latency, do you mean the speed at which Smartie communicates with the LCD?
You can set the parallel port timing multiplier, which basically slows down the port communications (you won't notice any difference in performance) to allow for slower displays and long cables.
In the Display Settings section of the Smartie Setup window, change the startup parameters from whatever you have (typically just "LPT1") to "LPT1,5". The 5 specifies that the comms will be 5 times slower.
If that doesn't work, try changing the port type in the BIOS - try SPP and EPP modes.

Hi Mattcro,
Yes, i think thats what i am after.
I do have it set to EPP mode in the Bios.
I also usually just let LCD Smartie run its standard default scrolling displays, but thats where it seems to get confused in any time within 2 hours.
Today, i set it to a single display and it seems to not have gotten corrupted, so i will continue to monitor that over the next 10 hours and see if its ok.
After that i will try your 'multiplier' option and report back.
Thanks

A static display (just plain text, no scrolling etc) will cause Smartie to write the data to the LCD only once, and then do nothing more, so scrolling text and plugins is a better stress test for debuggin the LCD wiring and comms.
Try the timing multiplier - if 5 doesn't work, try 10 or more. If that doesn't work, you might be one of the unlucky people for whom nothing seems to solve this problem. Many people have no problem with the parallel port connection, but there are some setups that don't seem to work properly.
In this post there is mention of removing the R/W signal to the LCD and connecting the R/W pin (5) to ground. This is worth trying, since Smartie doesn't actually read any data from the LCD (as far as I know).
