TOPVIEW ANDTWISTED MOUNTING

The prefered view of the eDIP128 is bottom view, (6 o'clock).

The eDIP can be mounted turned around 180° to gain a top view display (12 o'clock). To set the

viewing direction you have to run (e.g. in PowerOnMacro) the command 'ESC DO 2' (refer to p. 13).

In addition it is possible to mount the display turned with 90° or 270° to gain a portrait mode display

with 64x128 pixels.

POWER DOWN MODE

To save energy (battery operation), you can activate one of three power-down modes by means of the

command ‘ESC PD n1’ (see page 15 below).

Mode 0 (25µA): The LED illumination is switched off, and the contents of the display become

invisible although they are still there. In power-down mode including suppressor

diodes, the eDIP128 requires up to 1000 µA (delivery state). The suppressor diodes

can be deactivated by removing the two 0

Ω resistors. Then powerdown current of

typically 25 µA is reached. They are labeled with R

Important: When deactivating the suppressor diodes, it is essential that the polarity of

the display is correct all the time: GND, VDD (pin 1 + 2). Even very brief polarity reversal

or overvoltage can damage the display immediately and irreparably.

Mode 1 (1mA): The LED illumination is switched off, the contents of the display stay visible. Current

consumption is reducing to 1mA. This power down mode is mainly usable with the

versions EA eDIP128W with positive display, because they are readable without

backlight.

Mode 2 (4mA): The LED illumination stays on and the display content is readable. The current

consumption reduces to 3-4mA plus adjusted LED current. Therefore you can use

the eDIP in dark surroundings and dimmed illumination under e.g. 10mA.

The eDIP128 can be woken up from power down mode with a low level on pin 13 (WUP), or the

adressing via I²C.

In additon the eDIP128 can be woke up by using the touchpanel (independed from position).

After wake up, special WakeUpMacros can be used (refer to p. 24).
