D-Vine 4 parallel vfd

trying to get 2x16 parallel port vfd working with smartie 5.4 and getting bizarre behavior. Using the HD44780.dll plugin, port $378. When I first startup Smartie, everything works perfectly, but after a few minutes, the second line disappears....no output. If I stop and then restart smartie the same thing happens. Seems like a timing issue since it works @ first. Any ideas??????

Can be a timing issue, VFD are slower than normal LCD's.

Please try

Code: Select all

$378,5

as startup parameter! This will slow thing down a little bit.

(there are no spaces between the numbers, just a comma)

that didn't help

What should the parallel port setting be? ECP, EPP, ECP+EPP? should I have the old parallel port driver (DLPortIO) installed?

ECP+EPP should cover both cases.
What driver is installed now?

Can you also try InpOut32?

tried inoutp32 1.2....same problem....this is frustrating. Any suggestions for replacement vfd which will work?
