APPLICATION EXAMPLES
Different wiring must be used depending on the interface and the power supply. 2 additional capacitors
are required for 3.3 V operation.
Note that the COG technology means that the current capacity of the outputs is limited. Therefore, a
large load on the bus may cause signal loops and unclean levels. If in doubt, additional pull-down
resistors (8051) are required or additional waits/NOPs must be incorporated.
USB-TEST BOARD EA 9780-2USB
For easy startup, a USB test board is available that can be connected to a PC. An USB cable and a
Windows software is supplied with the product. This allows individual text and to be displayed directly
on the connected display.
SIMULATION WITH WINDOWS
A simulator window also displays the contents of the display. The software can simulate all the
displays and colors even without the hardware. You can download the software free from our website:
