Hi,
I've updated the serialVFD driver. Many changes and improvements have
been made since the last version.
This are the important ones:
- Support for parallel connection added.
- Improved user-character handling to reduce data send to the display
(fixes flicker and reduces cpuload slightly).
- Backlight and brightness functions revised. The client can switch
between 2 brightnesslevels like in the CFontzPacket-driver.
- Driver has been successfully tested on a FUTABA M402SD06GL VFD.
Thanks to Robert Buchholz.
- Documentation updated.
Stefan

- The serialVFD-driver should work with all NEC FIPC8367 based VFDs:
- NEC FC20X2JA
- NEC FM20X2KB-AB
- NEC FC20X1SA-AB/AA
- ...
- Tested only on: NEC FM20X2KB-AB
- The driver also works (tested) on "KD Rev 2.1" (an ATMEL AT90S....
- based FM20X2KB-AB replacement).
- Note: Above char. 128 the FIPC-displays and KD's charactersets
- are different.
-
- The driver may work or will be easy to get working on the following
- Displays / Controllers (not tested!).
- Display: Controller:
- FUTABA M204SD01AA FUTABA 5P00A016
- Noritake CU20026SCPB-T (microcontroller)
- Noritake CU20045SCPB-T28A ?
- ... or compatible.
- (most Futaba/Noritake 7x5 dot VFDs with serial(rs232) interface
- (including serial(rs232)/parallel types))
- Maybe there are little changes in the commands to do to get all
- functions to work correctly. But because of the similarity of the
- protocols, it wont be much work.
-
- If you want to add a new device to the driver add a new section
- to the displaytype-switch-case in the init-function and fill it
- with the corrrect commands for the display.
- (Try wich displaytype works best with your display, copy and modify
- it's section that is the easiest way I guess.)
-
-
- On this page I found pictures and datasheets of the VFD's:
- http://www.maltepoeggel.de/html/vfd/index.html
-
-
-
-
- To enable the bignumbers on 2-line displays (only this driver supports
- this yet) you have to edit "/clients/lcdproc/chrono.c" before compiling.
- In function "big_clock_screen" you have to replace the "4" by a "2" in
- this line: "if (lcd_hgt < 4)".
-
-
-
- This driver uses the serial mode of the displays.
- It is NOT possible to connect most of the displays directly to the
- serialport. The signal has to be inverted. I use the following
- circuit to do that job.
-
- Computer Display
- (signal)
- HDD Powerconnector

- Pin 2 ---- GND

- KD Rev 2.1:
-
- blue connector (6pin in a row) (the important one!):
- --------------------------------
- | +5V +5V RxD GND GND GND |
- --------------------------------
- NOTE: hold the display in that position where you can read
- the "KD Rev 2.1" marking normally!
-
- gray connector (10pin 2 rows):
- Do not use. (the ATMEL ISP connector I guess)
-
- The two jumpers next to the gray connector:
- Normally not used.
- You can activate two different testmodes with them.

+ The driver should operate most of NEC, Futaba and Noritake 7x5 dot VFDs with
