EA IC202

GENERAL

The EA IC202 high-level Graphics Controller links your system processor to your graphic display.

Inputs accepts a serial asynchronous RS-232 interface. The graphics controller includes complete

graph routines and various character sizes.

Programming is made by high level language graph commands; time consuming programming of

character sets and graph routines is not necessary anymore. Expenditure for developing of your

product is reduced significant and several features are gained on top of it:

- no timing problems with fast processor bus

- enough memory space (operating memory and characterset memory especially for µC)

- no time consuming graphic calculations which would slow down processor speed

Connecting to hardware is very simple. Display and main processor are connected directly. Drivers,

decoders or port modules are not required. A simple display input need 1 wire (RxD) only. 2 up to

maximal 4 external components will complete the circuit: a quartz with 2 capacitors and a reset-

capacitor. No external components are needed when you operate with 8051-compatible systems.

Clock and reset signal can be taken from main processor.

HARDWARE

Supply voltage of system is +5 Volts. Data transfer is asynchronous serial in RS-232 format at CMOS

level. Data format is set to 8 data bits, 1 stop bit and no parity. Baud rate can be selected on 3 pins

from 150 Baud up to 115200 Baud. Handshake lines RTS and CTS on board too. There is no

interpretation needed for small quantities of datas.

Data format:

Additional 8 I/O-ports are available for free usage. This may be wired as inputs or outputs on individual

desire. Possible application is switching of backpanel illumination or reading of several keys.

SOFTWARE

Programming of this High-Level graphics controller is performed by commands like i.e. "draw a

rectangular box from (0,0) to (64,15) which origins in top left hand corner of display". Therefore the

serial interface has to transmit this sequence of bytes: $52 $00 $00 $40 $0F. Characters string can

be placed precisely to the pixel. Mixing of graphic images with text elements is possible anytime.

Three different character sets are available where each of them can be zoomed by factors 2-, 3- or

4-times. The biggest character set 16x8 allows when using 4-x zoom (=64x32) a totally filled display

with letters and numbers.

TEST MODE

As long as pin 9 (RTS) is after Power-On or after Reset connected with GND, the graphics controller

is in test mode. Display shows now a marked flashing box. When

connection Pin 9 (RTS) to GND is removed, the graphics controller

returns to normal operation mode but testbox still remains visible.

TECHNICAL DESCRIPTION

Datas are valid for Ta= 0..+70°C and VDD= 5,0V ±20% if not noted otherwise.

POWER-SAVE FUN CTION

Power-Save function allows use in

battery powered devices. Command

"Q $01" puts the High-Level-Graphics-

Controller from normal operation into

power save mode. Current

consumption (without display) is

reduced to about 100µA. Because

display is connected to supply voltage,

still some mA current are drawn

depending on type of display. Total

content of display, i.e. all by your own

created characters and bargraph-

definitions remain preserved. In Power-

Save-mode no commands will be accepted and executed (RTS at H-level).

Command "Q $02" sets controller and a transistor driven display (see application example on page 5)

to Power-Save Mode. Note that content of display gets lost but all by your own created characters

and bargraph-definitions remain preserved. Also this mode will not accept and execute commands

(RTS at H-level).

An at least 10ms wide reset puls (H-level) turns the graph controller back to normal operation. The

internal registers are resetted as listed in above table.

DIGITAL IN-/ OUTPUTS IO 0..7

8 pins of this High-Level Graphics Controller may be used as free available programmable In- and

Outputs. Also mixed operation of i.e. 3 Outputs and 5 Inputs is possible.

Output circuit

Command "Y n1 n2"1) sets any selected pin IO 0..7 to H- or L-level; it can

be compared with an Open-Drain output without pull-up resistor. Current

flows only when L-level is applied. A single

pin may be loaded with max. 10mA, all pins

together may be loaded with 26mA in all, i.e.

2 pins @ 10mA plus 1pin @ 6mA. Its

possible i.e. to connect and switch a LED

directly. Higher current can be provided by an external transistor circuit.

Note that after Power-On resp. in Power-Save-mode all outputs will be at

H-level.

Input circuit Input pins accept voltage levels between -0,5V and

+0,2V*VDD-0,1V. Leakage current is max. ±10µA.

Trigger levels are listed in table of technical

description on page 3. Command "X n1"1) allows read

in of datas on each individual pin IO 0..7. Voltage

level must be stable all over read in procedure. There

is no built in debounce function.

APPLICATION EXAMPLES

with Power-Save Function

Standard application

APPLICATION HINTS

In order to ensure trouble free operation, you should be aware of basic construction rules in digital

electronic applications already during development of circuit routing:

- Watch for straight ground routing in your layout (no ground loops)

- Supply voltage distribution is best performed star shaped by widend conductor tracks, preferably

by multilayer boards with seperate power supply layers.

- Components resp. cuircits with high or variable current consumption need seperate supply cables.

Remaining cuircuits must be decoupled and filtered on demand. Also LED-illumination of display

should be supplied seperate.

- Use blocking capacitors at all active components.

- Keep tracks carrying high frequency signals resp. high rising slopes as short as

possible (XTAL1 and XTAL2 !)

ATTENTION

handling precautions!

DESCRIPTION OF VARIOUS GRAPHICS FUN CTIONS

The following pages show detailed descriptions in alphabetical order for each individual function.

Examples are shown as hardcopy in an enlarged window of 50 x 32 pixel once the command has been

executed. Examples show all transfered bytes in Hex code.

A x1 y1 n1 Set ASCII-Characters

A character n1 will be displayed on coordinates x1,y1 with preset font 'F' and text

mode 'T' (setzen / löschen / invertieren / replace / invers replace / pattern). Origin is

(0,0) at top left hand corner of display. Datas for coordinates apply also to top left

hand corner of a given character. Note: Font No.1 shows capital letters only.

Example: $41 $13 $02 $45

Character 'E' is displayed at coordinates 19,2

Preset font: 6x8, width 2x and height 2x

Text mode: Replace and black pattern

B L/R/O/U nr x 1 y1 x2 y 2 aw ew pt n Define Bar graph

Up to 8 bargraphs (nr=1..8) can be defined, which may oscillate to L=left, R=right,

O=up or U=down direction. Bargraph full level range coordinates are described from

x1,y1 to x2,y2. Scaling of bargraph is performed by starting zero position aw

(=0..254) and max. ending position (full size) ew (=0..254). Bargraph always is

displayed in inverse-mode using the ptn-pattern type: the background remains

preserved in any case. (Note: executing this command only the bargraph range is

defined but nothing is visible on display).

Example: $42 $4F $01 $04 $02 $09 $1E $04 $14 $01

Defines bargraph no. 1 which oscillates vertical up to top. At full level its coordinates ranges from 4,2 to 9,30.

Displayed start- and end values represent current values of 4..20 mA. (Hardcopy shows bargraph at its full level

operating at $42 $01 $14)

B n r value Draw Bargraph

Bargraph number n1 (1..8) will be adjusted to a new value (aw <= value <= ew).

If value > ew, than final value will be displayed. Bargraph must be defined before,

see above example.

Example: $42 $01 $0A

Above defined bargraph no. 1 is set now to value 10.

C n1 Display Control

Switches display On (n1=1) or Off ( n1=0); all display datas remains preserved and

commands can be executed furthermore.

Example: $43 $00

Content of display becomes invisible, but remains preserved.

EA IC202

D L/I/S Display Command

Total content of display will be: L=deleted (white), I=inverted or S=filled (black)

Example: $44 $49

inverts total content of display

E n1 daten Define Character

Up to 16 characters can be defined by yourself (depending on font size). This characters

have ASCII codes from 1 to max.16 and remain stored in an internal 64 Byte RAM-area

until the supply voltage is switched off. Up to 16 characters can be defined with font no.1,

up to 10 characters with font no.2 and up to 4 characters with the biggest font, no.3.

Attention! If several characters out of different fonts should be defined, than you have to

consider that i.e. one character from 8x16 font, code 1 needs the same RAM-space as a

character from 4x6 font, code 1 to 4 (see table nearby) !

Example 1 :

$45 $03

$04 $02 $7F $02 $04 $00

defines a up pointing arrow with ASCII-No. 3

and with a preset 6x8 character set.

Example 2 :

$45 $02

$00 $00 $00 $FF $00 $00 $00 $00

$04 $08 $10 $3F $10 $08 $04 $00

defines a down pointing arrow with ASCII-No. 2 and with a preset

8x16 character set.

F n1 n2 n3 Set Font

Font No. n1 (1=4x6 capital letters only; 2=6x8; 3=8x16) is choosed.

Different zoom factors (1..4x) for width n2 and for height n3 are selected.

Example: $46 $02 $03 $04

6x8- font is now set to 3-times width and to 4-times height.

Beside hardcopy shows letter 'E' from font 6x8 in different sizes.

G x1 y 1 x 2 y2 Draw straight line

Straight line is drawn from coordinates x1,y1 to x2,y2 taking into account

the preset graph mode 'V' (set / clear / invert).

Example: $47 $03 $14 $28 $06

Draws a straight line from 3,20 to 50,6.

T L/R/O/U n1 ptn Set Text Mode

Overlay combinaton mode n1 and pattern ptn sets

ASCII-characters 'A' in text mode and displays a

character string when settin g to 'Z'. For display a

character string (command 'Z') the typing-direction must

be set by: L=left, R=right, O=up and U=down.

Example: $54 $52 $03 $03

Initiates the overlay mode for text functions with gray

characters (pattern 3 = 50% black), inverts the

background and writes character string from left to right.

Overlay combinaton mode n1:

1 = set: black Pixel without regarding previous value (OR)

2 = delete: white Pixel without regarding previous parameter

3 = invert: black Pixel turns to white Pixel and vice versa (EXOR)

4 = replace: clear background and set black colored Pixel

5 = invers replace: fill background and place white colored Pixel

U x 1 y 1 data Upload picture

An image will be loaded at coordinates x1,y1

daten: - 1 Byte for width of image Pixels

- 1 Byte for height of image Pixels

- Image datas: Qty = ((height+7) / 8) * width Bytes.

1 Byte equals 8 vertical Pixel on screen;

0 = white, 1=black; LSB: top, MSB: bottom;

Image builts up from left hand to right hand.

The program BMP2BLV.EXE on disk EA DISKIC-1, wich is available as an

accesory, generates from a monochrome Windows-Bitmap- Graphic the

datas for our Image inclusive width- and height information.

Example : $55 $09 $04 $0C $0C

$F0 $FC $FE $FE $F7 $BF $BF $F7 $FE $FE $FC $F0

$00 $03 $07 $06 $0D $0D $0D $0D $06 $07 $03 $00

loads beside shown image at coordinates 9,4.

V n1 Set Graphics Mode

Set overlay combinaton mode n1 i.e. for following

grap h - functions: set dot 'P', draw straight line 'G',

continue drawing straight line 'W', draw rectangular box

'R', draw box with rounded corners 'N', fill area

with pattern 'M'.

Example: $56 $03

sets overlay mode to inverse.

Beside example illustrates drawing of a rectangular box in overlay modes set, clear

and invert.

Overlay combinaton mode n1:

1 = set: black Pixel without considering previous parameter (ODER)

2 = delete: white Pixel without regarding previous parameter

3 = invert: black Pixel turns to white Pixel and reversed (EXOR)

4 = replace: clear background and set Pixels; area with filling pattern ptn only

5 = invers replace: fill background, delete Pixels; area with fill pattern ptn only

EA IC202

W x 1 y 1 Continue straight line

Draws a straight line from last drawn line end resp. (see page 3: Last xy) to

x1,y1 under considering the Graphic Mode 'V' (set / delete / inverse).

Example:

$47 $00 $00 $10 $04

$57 $16 $1B

$57 $30 $0F

Draws first a straight line from 0,0 to 16,4; then continuing from 22,27 to 48,15.

X n1 I/O Read Por t

Reads in Port (n1: 0..7 = I/O: 0..7).

When n1 = 8, all I/O 0..7 are read in binary; I/O 0: LSB, I/O 7: MSB

See application on page 4.

Example: $58 $02

reads in signal at I/O 2 and transmits L-level a $00 resp. H-level a $01 via RS-232

Y n1 n2 I/O Set Port

Changes port value (n1: 0..7 = I/O: 0..7) into value n2 (0=L-level; 1=H-level; 2=invert port level).

When n1 becomes 8, all I/O 0..7 will be transfered as binary value n2; I/O 0: LSB, I/O 7: MSB

See application on page 4.

Example: $59 $02 $01

sets port I/O 2 to H-level

Z x 1 y 1 ASCII... NUL Write character string

Writes a character string ASCII.... beginning from coordinate x1,y1 honoring preset

mode 'T' (set / delete / inverse / replace / inverse replace / pattern / direction).

Character strings must be finished with NUL ($00). Origin (0,0) starts in top left

hand corner of display. Datas of coordinates refer to top left hand corner of

character. Note: Font Nr. 1 has capital letters only.

Example: $5A $06 $0B $54 $65 $73 $74 $00

writes character string "Test" starting at coordinate 6,11.

Font: 8x16 with normal height and width.

Text mode: Writing direction is from right hand, Overlay mode is Replace with Pattern Black.

? Query display type

Resolution of display and way of building up an image will be displayed. High-Level-Graphics Controller

IC202-PGH features a permanent resolution of 128 x 64 Pixel and organizes image building up in vertical

direction. This command is available for communication of external programmes with our High-Level-Graphics

Controller. IC6963-PGH is designed for displays with i.e. Toshiba controller managing variabel resolutions up to

240x128 Pixel with horizontal image building up organisation.

Example: $3F

This command transmits first the resolution X- (128) and Y- (64) and then the way of image building up ('V') in

vertical organization via RS-232 interface.

EA IC202

INTEGRATED FONTS

High-Level Graphic Controller EA IC202

incorporates 3 integrated character sets (Font1:

4x6 Pixel; Font2: 6x8 Pixel and Font 3 8x16

Pixel). Each character set can be used in 1-,

2-, 3- or 4-times height. Independant of height

the width may be doubled, tripled or quadrupled.

4-16 self defined characters will be stored as

long as the supply voltage is switched on,

(see command 'E').

Each individual character can be placed exactly

by pixel. You may mix text with graphics in any

way at your desire. Also characters with different

sizes can be used in common.

BAUD RATES

Various baud rates can be selected

depending on System Clock (Quartz,

Ceramic Resonator) for RS-232 data

transfer. Its done by connecting pins

BAUD0..2 and QTYP to VDD or to GND-

Pegel. Programmable baud rates are

shown in this table (0: GND, 1: VDD).

ADRESSING

Up to 4 High-Level Graphics Controller are adressable on a single serial port.

The individual adress is set on pin ADR0 and on pin ADR1.

Caution! Simple parallel connection of handshake lines RTS respectively

transmitter lines TxD results in interfering output signals, therefore you have

to use an additional logic circuit to prevent data crash. We recommand an

OR-logic for RTS resp. AND-logic for TxD.
