6.5.LCD Module

A LCD module can be connected to the connector J13. Any module that conforms to the pin connections and has a KS0066u compatible

controller can be used with the tutorial code. The LCD module uses a 4bit interface to reduce the pin allocation. No contrast control is

provided; this must be set on the display module.

Table 6-5 shows the pin allocation and signal names used on this connector.

The module supplied with the CPU board only supports 5V operation.
