This module is shown in Figure 4-24. It consists of the following main components:
1) 8 LED.
2) 8 coding switches.
3) Interface socket.
Descriptions of this module are as the following:
1) 8 LED are on when the I/O outputs HIGH voltage.
2) Each LED is controlled by a separate coding switch. When this module is not in use it is suggested that the
corresponding bit be disconnected so as to avoid causing unnecessary disruption.
3) You may test the I/O ports of other MCU by using the interface socket.
4) The CD-ROM includes some simple examples of this module, which cover "lit each LED" a "Simple play-in-turn", just
