This document gives the commmon hardware setup
for using an Epson SDU1356B0C evaluation board 
on a PCI bus PC, under Windows, to demonstrate
various Kyocera color LCD modules.

KEY POINTS
  Adjust the VDDH variable resistor as high as
    possible - all the way clockwise.  
  Set jumper JP2 for the logic voltage of LCD
  Do not rotate 4 bit per pixel images. 


SDU1356BOC BOARD SWITCHES AND JUMPERS
  On the dip switch: 1,2,3,4,6,10 closed
     and 5,7,8,9 open.
  JP1 1-2 (upper position)
  JP2 x-x LCD logic voltage selection.
        1-2 (upper position) = 5.0V LCD logic 
             for 057 and 072 panels
        2-3 (lower position) = 3.3V LCD logic 
             for most other LCDs.  Check specs.
  JP3 all positions n/c (open).
  JP4 1-2 (upper position)
  JP5 n/c
  JP6 1-2 (upper position)
  JP7 1-2 (upper position)
  JP8 1-2 (upper position)
  JP9 n/c

  VLCD variable resistor is irrelvant to Kyocera LCD.
  
  VDDH variable resistor must be turned as far as
    possible clockwise to provide maximum LCD 
    voltage to the similar variable resistor "VOL1"
    on the Kyocera KK5 board, where actual adjustment
    is more convenmient.

CONNECTIONS
  Copy the eval board drivers (13xx) to an 
     out-of-the-way directory on the C: drive.
  Power-off.
  Connect a 40 pin ribbon cable to the board.
    (an standard IDE cable works fine).
  Connect the other end to the Kyocera KK-5
     board that you will be using, with
     display switch off and connect the LCD
     to the KK5 board.  
  Set the SDU board jumpers/switches as above.
  Insert the board in the PCI slot.
  Power-on.
  When prompted by Windows software, tell it
    where to find the 13xx drivers.  They
    seem to common to all the PCI bus 
    SDU eval boards, so you will only have 
    to do this once.
 
REFERENCES
  Epson web site is www.erd.epson.com.
  It has newer versions of the Epson manuals than 
     were distributed by Kyocera.  There are 
     separate manuals for the SDU1374BOC eval
     board, the SED1374 controller IC, and the
     various software programs. 

 The Kyocera LCD website is www.kyocera.com/lcd
     It has specifications for most LCD modules.
     Consult these specs for logic voltage,
     frame rate range, and pixel clock range,
     which you must set by jumper or configuration
     program.
     
     Consult these specs for required additional
     circuits such as "randomizing circuit"
     and bias voltage circuit.  If additional
     circuits are required by an LCD, then they 
     will be provided for demonstration on the
     KK5 interface board.  But the customer must
     provide them externally the final product.
     The MOD feature of the SED1356 IC can
     implement the requirement for a randomizing
     frequency, if you load its register properly.

  Consult the Kyocera demonstration kit manual,
     page 4-1, for a table of what KK-5 boards
     to use with what LCD modules.  However the
     more common LCDs are also covered by 
     LCD-specific notes in each 56B-xxx.txt file.
     Note that all KK-5 boards are assumed to be
     for the Epson boards.  The difference is that 
     they must have the 40 pin connector on top,
     and not the 30 pin connector in the middle,
     as found on otherwise similar KK5 boards 
     intended for Kyocera demo controllers.
 
 Consult the Kyocera manual for helpful pictures
     on how to use Epson's 1356CFG.exe program
     to configure Epson's 1356BMP.exe program
     for use with Kyocera's LCDs.

1356CFG.exe
  This program is used to configure 1356BMP.exe
  for a specific LCD panel.  Then 1356BMP.exe
  is run to initialize the SDU1356 board and
  display the .bmp image you select.  Since 
  Kyocera has lots of LCDs, I made lots of copies
  of 1356BMP.exe and renamed one for each
  specific LCD. For example 56B-38.exe is a
  copy of 1356BMP.exe configured for Kyocera
  3.8 inch panels.

  The first 9 lines of Kyocera's table 4-1
  must be set exactly into 1356CFG.  After that,
  you want the panel clock and the frame rate to
  be withing their ranges, as given in the Kyocera
  spec for the specific panel.  You probably want
  Non-display period lines to be 1 or 2 or a small
  number.  Finally you will be forced to choose
  a Non-Display-Period number of pixels acceptable
  to 1356CFG.exe.  As you enter one number, the 
  program will change some other number that you
  already set, in order to be maintain the 
  relationship among the frame rate, pixel clock,
  and non-display periods.  Repeat this until
  all values are acceptable.

  1356CFG requires a default color depth, in bits
  per pixel.  Choose whatever makes it happy, 
  because 1356BMP will change the SDU board to 
  the actual color depth of the file that you
  are trying to display.

  I abbreviate 1356BMP.exe as 56B-xxx.exe,
  where xxx identifies a Kyocera LCD.

DISPLAYING AN IMAGE.
  Execute the MS-DOS program from the windows
  program menu.
  Enter CD /1356  or  CD whatever to get
  into the directory.
  Run the 1356BMP program that you configured.

  for example

       C:\1356>56B-38  cb4-3224.bmp

  or 
       C:\1356>56B-38  pe8-2432.bmp /r90

  The /r90, /r180 and /r270 switches will
  rotate the image.  However the SED1356 IC
  spec disclaims 90 and 270 degree rotations
  for 4 bpp images.  8 bpp and higher are
  OK for all rotations.


PRINTING OUT REGISTER SETTINGS
  Within MS-DOS as above.
         C:\1356>1356PLAY
      The program displays "=" as a prompt.
      At =, enter XA to display all the registers.
      At =, enter Q  to quit.

   Practice this until you can do it 
   without looking at the screen.

   Then run the program with MS-DOS 
      "I/O redirection".  The screen contents
      will go into a new file, whose name you
      give each time.

         C:1356>1356play  >test1.txt

   Accurately type in XA and Q as above,
      but they will not display on the screen.
      After Q, the MS-DOS prompt will re-appear.

   The file test1.txt will contain the 
      register settings, for use by engineers

   I have made a set of register record files,
      to document each version of 1356BMP, for
      each Kyocera LCD module that I tested.
      For example 56B-389.txt records the
      the registers and my notes from running

           C:1356>56B-38.exe /r90

To get out of MS-DOS, enter
         C:1356>exit
