BS2 VFD CU40026scpb-T20 code
Archiver
Posts: 46,084
Hi I'm looking for code to use with my BS2, for learing.
I have used code with a 2x20 display (VFD)its a samsung 20F206DA4
it works great. I also have a CU40026CPB-T20 its a 2x40 VFD
I cant get it too display text, not sure how to run the coding for
this display. I also wanted to know if I have to have certain jumpers
set on the display for it to work?
Any jumper setting and code help would be great!!!
Thanks
Glen

The displays are limited to simple serial strings followed by a
carriage return. Treat them like a serial display but send the data
at 9600 baud TTL or use a MAX 232 chip to convert true serial data
out from a stamp or terminal program to TTL to the display. The
display uses a three-wire interface for +5 volts, Serial Data and
Ground to connector CN2 and there is a solder link configuration
required on the display to set the baud rate from 300 to 19200 at
JA0. When sending commands to the display like clear screen you need
to send ($0E) you can position the cursor top left by using CON 32. I
could never find a data sheet on these displays on the Noritake web
site but found all the information at http://www.farnell.com/uk.
Enter their part number 232464 for the 20 x 1 or 232490 for the 20 x
2 in the search box and download the pdf's
Try this bit of code that I used with my 20 x 1 display
N9600 CON $4054 'LCD Baud rate (9600) through MAX232
Clear_Screen CON $0E 'Clear Screen
Char_Space CON 32
Serout 0,N9600,[noparse][[/noparse]Clear_Screen]
Pause 1000
Serout 0,N9600,[noparse][[/noparse]"Hello",CR]

that I am getting on the display is garble and odd cheracters. Could be a
weak power supply, even though it is aregulated 5 volt supply.

Possibly, they are fairly current hungry at 200 - 400ma when running,
the 5 volt reg I'm using is a 1.5 amp 7805 with the voltage lifted
slightly to 5.2 volts using a 27 ohm resistor between the + pin and
ground off the reg. I reckon it's a baud rate problem as that baud I
gave you ($4054) is real RS232. Since my first message I have found
the display and the jumpers I have shorted for 9600 and operation are
JA0 & JA4 with 1, 2 & 3 open. What I will do is try my display
without the MAX232 inline and see I can get a fix on the baud and
email it over.
Cheers, Simon.

Very odd this but the baud rate is 84? According to the BS manual
this is for a line driver! ..anyway insert this line N9600 CON 84 and
you should have ASCII characters displayed. I also know that when the
display powers up if take about 2.5 seconds to get warm before
characters can be displayed and if you don't use position cursor (CON
$0E) the display scrolls from right to left. Good Luck. Simon.

solder that I put on J4, for none parity. Ive already soldered the J1
jumper. I tried it with and with out thde parity jumper.

Now Im trying to get text on the second line, to get it to scroll
from right to left and to verticaly scrol. Ive been over the VFd
instruction sheets several times and tried different code.This thing
sure works different fron my other VFD. any clues on how to do this
stuff.

These things are tricky and you have the advantage here as I don't
have a 20 x 2 display to play with. I'm guessing but I think its line
feed Hex 0A followed by a carriage return to move the line down one,
to scroll the characters its hex 12. Set them as constraints and I
think you need to send each command to the display one at a time with
a delay of a few milliseconds between each.
Good luck Simon.
