Product Information

SSD1815 Evaluation Kit

The SSD1815EVK is a evaluation kit (EVK) of the
SSD1815Z works with a LCD panel. The size of the display
is 96x64 dots and 1seperated icon row. Figure 1 shows the
outlook of top view of the EVK.

The EVK is composed of essential external compo­nents of SSD1815Z.There is one contrast control variable
resistor (VR1) and one selection jumper (J1) indicated in
the figure, for controlling the display contrast of the LCD
panel.

There is a header (U3) for connecting to external con­trol, eg. from MCU I/O ports. The pin assignment of this
header is given in the EVK Header/Connector section of
this document.

EVK Control

Software Control

The header on the EVK is used to control the COG
bonded SSD1815Z to perform desired functions. Details of
SSD1815Z, please refer to the Solomon Systech data sheet
of SSD1815.

Contrast Control

Jumper J1 is used to select if internal resistor network
for the voltage regulator is enabled for contrast control.
Open J1 will enable the internal resistor network.

The VR1 is a variable resistor connected between VDD and VL6 with tapping connected to VF of the SSD1815. If internal re­sistor network is selected (J1 closed), this VR will parallel to those inside the driver. In order to evaluate the exact performance,
this VR should be removed. Turn the VR1 clockwise to increase the contrast of the display, and vice versa.

EVK Header/Connector

The header is directly connect to the SSD1815Z I/O pins. Pin 1 is at the marking U3. Pin assignment of this header is given
as follow:

Users can use the EVK to build prototype application that matches pin out stated above. Do not connect anything to NC pins.
