Display plugin:Samsung 20L203DA310 (testdriver)

[tinkerman]

I'm hoping someone can help me out with a display driver or the correct testdriver settings. The display is a vfd from a POS display. It's a 20x2 RS-232 type (single wire com). This issues seem to be with scrolling lines and dynamic lines being wrapped or duplicated to the top or bottom lines.

Example:
|working @ 23% |
|working @ 21% |

| Smartie release 5.4 avail|
|Smartie release 5.4 avail |

The datasheet for the display in question can be seen here: http://www.utcretail.com/media/IOM/PD12 ... 93104G.pdf

The following dll setting work and seem to be fine: COM1,9600,8,N,1

This is what I currently have in the testdriver.ini:
[Test Driver]
Init=32,30,17
GotoLine1=24
GotoLine2=24
GotoLine3=
GotoLine4=
CharMap=


Note:The issue is similar to the pictures here (see CPU picture) but his setting didn't work for me.

I know I'm close. Thanks in advance!

I've got a POS VFD working now, I was having the same issues as you appear to be having, was all down to a slightly non-standard instruction set.

This is the testdriver.ini code for my screen...

Code: Select all

[Test Driver]
Init=12
GotoLine1=11
GotoLine2=11,13,10
CharMap=158,219

12 = clears the screen
11 = returns to position 0
13 = moves down one line
10 = Cant remember now, been a couple of months lol

charmap=158,219 = this is for the solid block character which did not appear in the standard charmap.

Give that a try and see what happens

Dave.

tinkerman, please try this:

[Test Driver]
Init=31
GotoLine1=16,0
GotoLine2=16,14
GotoLine3=
GotoLine4=
CharMap=

[tinkerman]

Update...I got it working just fine. The dimming feature works too. I ended up with this:

[Test Driver]
Init=4,64,31
GotoLine1=16,00
GotoLine2=16,20
GotoLine3=
GotoLine4=
CharMap=158,219

...thanks to Davegsm82, in your example the Char mapping gave me the "block". kewl! ...I didn't have that!

...thanks to caesar, I just had to change the starting position of line2. After checking the datasheet, I just had to convert your 14HEX to DEC, but I saw what you were trying to do. Having the datasheet is clearly a must.



...now I have to fit this into a nice enclosure

Great!
Have fun with it

[Davegsm82]

Excellent! Glad I was of some help to you

I dont think my VFD has a dimming feature, how do you use it?
