LCD Connectors

When using the character LCDconnector your LCDmust match the pinout shown here if it does notit is not compatible with this board. The only exception is the backlight LED’s. The jumpers on R1and R2 may be omited it your LCD does not use an LED for backlight. They may also becrisscrossed to reverse the backlight polarity.

When using the graphic LCD connector if your LCDdoes not match the pinout shown youmay use the universal connector shown later in this chapter. The same is true with thebacklight LED as mentioned earlier.

EXTPower Connector

This header allows you to provide power to the board with out using the 2.1 coax. You can supply 5vat Vdd or 14-7 volts to the Vin or Coax connector. The Coax pin will allow you to switch the poweron and off with the power switch header.


2: Hookup


Using the Universal Graphic Connector

The Universal LCD board has a special connector that can be jumpered for just about any GraphicLCD that utilizes a KS0107/KS0108 or HD61202 controller. If you are using one of the Sparkfunor CrystalFontz LCD’s mentioned earlyer you will install the header as shown in step 26.

The LCD must also have a built-in negative voltage generator.

To use the universal connector you must install the 20 pin female header into the top row as shown.

Now you make jumpers from row 2 to row three to convert the pinout on your LCD to that of theboard. As an example here is a list of jumpers to make the header compatible with a POWERTIPPG12864ERS-INN-H graphiv LCD.

A2 - B3B2 - A1C1 - C2D2 - P3E2 - O3F2 - Q3G2 - D3H2 - E3I2 - F3J2 - G3K2 - H3L2 - I3M2 - J3N2 - K3O2 - L3P2 - M3Q2 - N3R2 - R3S2 - R3T2 - T3

Note that the jumpers may be placed on the top of the board orbottom of the board or a mixture of both.

If your LCD does not have a LED back light then leave thejumpers on BL+ and BL- off. It’s then up to you to provide thecorrect power to the backlight on your LCD.

IF your graphic LCDdoes not have a negative power source youwill need to provide it at Point E on Q3.

Power Switch

Use this header to connect a switch. This will allow you to swithch the power to the board on andoff. If you dont plan on using a power switch you should place a jumper on this header.

DB9 Connector Selection

You may select the ports the TX and RXpins are connected to on the DB9 Connector. This willallow you to program the Dios and then use the UART as well.

If you are doing a lot of UARTtesting you can connect a DPDT switch to this jumper and switchthe connection as needed.


2: Hookup


LCD Type

Depending on the type LCD you are using you will need to set the following jumpers for properoperation. !!!Warning !!! Always set the LCD type jumpers with the power off before you placethe LCD into its appropriate socket.

2: Hookup


Backlight Hookup and Operation

BL+ is tied to Vdd and BL- is tied to Port 13 on the Dios. To turn on the backlight we set Port 13 tooutput and drive it low as in:

output 13low 13

Port 13 is also a PWM generator on the Dios so you can also dim the backlight using the PWM library.

The DiosUGLCD library also has a command called GLCDLED that lets you control the backlight.

Normally R1 and R2 are just jumpered. This delivers just under 5v when the backlight is on full. Ifyour LCDneeds a lower LED voltage you may need to replace one of the jumpers with a resistor.

Using a Jameco #658953 (Hantronix HDM64GS12L-4)

In order to use the Hantronix Grpaphic LCD you need to add the jumper shown below. Important: Once the jumper wire is installed you may not use a character LCD unles the wire isremoved. Failing to do this could damage the LCD or board.

In addition you need to remove jumper 31 if youinstalled it previously. This jumper is seldom used soits removal will not affect funtionality.

Make sure you set the proper graphic jumper asshown on the previous page.


The Universal LCD board was designed to make it easy to connect both character or graphic LCD’sto the Dios. The board is compatable with the following displays:

CharacterAny parallel character based LCD that uses a Hitachi HD44780 or equivalent controller. The LCDmust have a top mount pin set.

GraphicThe 20 pin connector is used to connect your graphic LCD. Note that this connector is compatiblewith the CrystalFontz LCD models

3: Operation


Graphic LCD Operation

The Graphic LCD is a bit more complicated, however with the DiosUGLCD.lib library the operation isa bit easyer.

Before we get into the library lets look at how the KS0107/KS0108 graphic controllers work.

KS0107/KS0108 Overview

The Universal LCD board is compatible with graphic LCD’s that are controlled by the KS0107/KS0108or compatible controller. This is a very popular controller and has made its way into many GraphicLCD’s.

In many cases the actual Graphic LCD will have multiple controllers stacked to create larger displaysizes. This board and library are compatible with those displays with dual controllers.

When writing to the controllers the CS1 and CS2 pins will be selected to turn on the appropriatecontroller. It is also possible to access both controllers at once. This is particularly nice wheninitializing and clearing the display.

The KS0107/KS0108 does not have a character generator so we provide it in software library.

Dios Library Overview

As popular as the KS0107/KS108 controller is, It does have its negatives. For one just about everypiece of documentation Ihave seen regarding this controller has terrible errors and are very hard tofollow. Also the nomenclature used seems to be counter intuitive.

For this reason I have created a set of libraries to access the low level memory of the LCD’s. Iwillbe using my own nomenclature that is much more intuitive.

It’s not necessary that you understand the low level technical layout of the libraries or the controller.I am simply presenting this information so you can expand upon the library if you wish.

Display layout (low level)

Display pages

The display is devided up into two sections Icall pages.

Each page displays 64x64 pixels and is controlled by its own controller. Many of the lower level librarycommands will contain a parameter for selecting the appropriate page.

Page 1 Page 2


3: Operation


Each page has 8 lines numbered 0-7.

Each line has 64 positions that contain a 1 pixel wide by 8 pixel tall strip.

These strips can be writen to or read from with the low level commands.

Display layout (high level)

At the high level we dont concern our selves with the the pages and strips. We simply issue acommand and the inner workings are handled for us.

Character Display

First lets look at the software character generator layout. The characters are 6x8 with only the 5x7portion of the character showing.

The display has 8 lines of 20 character data. An internalpointer keeps track of the current position and isincromented with each character sent to the display. Ifthe pointer reaches the end of the line the character willbe placed on the next line.

3: Operation


Pixel Display

The software pixel generator commands will automaticly take care of selecting the correctpage,line,pos and bit in the strip.

The routines read in the current strip where the pixel is located and set or reset the bit as indicatedthen write the modified strip back out to the display.

The pixels are aranged with the x coordinate along the width with the lowest pixel at the left (0) andthe highest at the right (127).

The y coordinate is aligned with the height with the lowest pixel at the top (0) and the highest at thebottom (63).

You write to the pixels with the GLCDsetpixel command. This command is independant of thecharacter display system and can display right over the top of the characters.

Software Library

The library is included with Dios Compiler versions 2.0.10 and greater. It will be added to your sourcecode any time one of the graphic commands are used.

High Level Character Commands

These high level commands are used to write characters or initilize the display.

X coord, 128 Pixels 0-127

Y coord, 64Pixels 0-63

Initilize Graphic LCD

GLCDinit or GLCDint2

The GLCDinit command is used to setup the ports and initialize the graphic LCD.It must be the first graphic LCD command called. See Example 1

Use the GLCDint2 command if you are using the Sparkfun or Hantronix(Jameco) graphic LCD.
