EA GE120-5NV24
GENERAL
Our graphics unit LCD EA GE120-5NV24 is designed for small up to medium quantities. Nearly all
known processor systems can be connected within a few hours work to an 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 includes
complete graphics routines and various character sizes to drive the display.
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 a single 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 2 solder straps from 300 Baud up to 9,600 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 J2 eyelet strip for freely usage. This may be wired on your
individual desire. Each output port drives a load of max. -10mA.
SOFTWARE
Programming of this graphics unit is performed by commands like i.e. "plot a rectangular box from (0,0)
to (20,15) which origins in top left hand corner of display. Therefore the serial interface has to transmit
this sequence of bytes: $52 $00 $00 $14 $0F. Character strings can be placed exactly to the pixel.
Mixing of graphics images with text elements is possible anytime. Two different character sets are
available where each of them can be zoomed 2x, 3x and 4x.
ATTENTION
handling precautions!
