problem with VK204-25

Could someone please help?

I just bought the VFD yesterday, i followed the instructions exactly.
I am using LCDC.

When i use the option test display it is fine, it displays the text fine.

But when i do anything inside the program like just scrolling text i see full blocks go across the screen every other second?!

can anyone help please?

cheers

In LCDC setup have you selected the definition file for the vk204? Also make sure the com speed in LCDC is set to 19200...

Rob.

p.s. what OS are you using? Have you tried programs other than lcdc? See the 'cool uses' section on www.matrixorbital.com

i have changed the port speed to 19200 in both the program and the com port settings.

I have also made sure i have the correct defination file open .

I am using windows XP.

Ok, i will go and try some other programs.

Does the virtual screen show correctly? Can you get a screenshot...

The virtual screen is ok.

When i press start on LCDC it goes funny, soon as i press stop it goes ok.
I have tried to catch the screen here.

thos blocks appear randonmly and go from right to left

I guess you have a test screen on there - what is in each line?

i am using windows XP Pro Build 2600

The only thing that was in the line is the text. I made sure nothing else was loaded.

I will try another PC.

Weird - have you got another com port you can try? Possibly even another cable? I'm not sure what else to suggest I'm afriad. What about other apps? LCDSmartie for example? Does that work?
