Tutorial – A Memory Gauge Example
This section of the guide takes you step-by-step through the process of connecting and setting up a new display. We’ll use a fairly
simple numeric “Memory Gauge” display as an example, as shown in Figure 13.
Figure 13.
Details of Memory Display
The display is 33mm x 15mm overall size, with 30 active segments. The connector is 32 ways 0.5mm pitch contacts on
the bottom of the display, with pins 31 and 32 uncommitted.
We are going to connect this display to the DA8521 Evaluation 64 Segment Board. We’ll assume that the display is to
be connected to the board directly, and that FPC connectors will not be used.
This information has been provided by E-ink, which should allow simple connection and allocation of the segments.
It is possible that you do not have this information to hand, (i.e. the person who has it is on holiday!), or the information
might be out of date, in which case I will lead you through the steps to sort this out later in this tutorial.

Connecting the Display Hardware
First, connect the display to the PCB. This is achieved by positioning the display contacts on the 0.5mm pitch connector
J6 on the top side of the PCB (see Figure 14), securing the contact with a piece of matt adhesive tape. Use a type with
low stickiness to avoid leaving residue on the PCB. For the 0.5mm pitch the connector of this display, it is just possible to
align the connector correctly with the naked eye. For smaller pitch connectors, some magnification is required.
