GENERAL
Our graphics unit EA GE128-6N3V24 is designed for small up to medium quantities. Nearly all known
processor systems can be connected within a few hours work to our attractive and informative looking
display because of it's simple way to program, it's small outside dimensions and it's excellent
supertwist contrast. Input ports accept a serial asynchronous RS-232 interface. The display contains
complete graph routines to drive the display and includes also various character sizes.
Programming is made by high level programming language graph commands; time consuming
programming of character sets and graph routines is not necessary anymore. Development costs for
your products is reduced significant and additional 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
Drivers, decoders or port modules are not required. Display control can be made in simple cases
through one RxD line only.
HARDWARE
Supply voltage of system is +5 Volts. Data transfer is asynchronous serial in RS-232 format at CMOS
level with true RS-232 level (±10V) or with 5V CMOS level. Data format is set firmly to 8 databits, 1 stop
bit and no parity. Baud rate can be selected on 3 solder pins from 1,200 Baud up to 115,200 Baud.
Handshake lines RTS and CTS are available also. On small amounts of datas there is no
interpretation required.
Data format:
Additional 8 I/O-ports are available on J3 eyelet strip for freely usage. This may be wired as inputs or
outputs on individual desire. Possible application is switching of a transistor / relais (IL
max
=10mA) or read
in of keystrokes / switches. Required pullup resistor network can be soldered dierctly onto pc- board.
SOFTWARE
Programming of this High-Level graphics controller is performed by commands like i.e. "plot 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. Character strings can
be placed
exactly to the pixel. Merge of graphic images with text elements is possible anytime. Three
different character sets are available where each of them can be zoomed from 2x, 3x to 4x. The biggest
character set 16x8 shows when using 4x zoom (=64x32) a totally filled display with letters and numbers.
TESTMODE
As long as pin 15 (RTS) is after Power-On or after Reset connected with GND, the graphics controller
is in test mode. Display shows now a cross marked flashing box. When
connection Pin 15 (RTS) to GND is removed, the Graphics controller
returns to normal operation mode but testbox remains still visible.
