C DEMO BOARD OPERATION
The PICkit™ Serial I
2
C™ Demo Board was designed to easily connect to the PICkit
Serial Analzyer (DV164122). Refer to the PICkit Serial Analyzer User’s Guide
(DS51647) chapter on I
2
C Master Communications mode for configuration and
operation information of the PICkit Serial Analyzer.
The PICkit Serial Analyzer provides the I
2
C master mode serial communications and
power. The PICkit™ Serial I
2
C™ Demo Board devices all operate in the I
2
C slave
mode. Figure 2-1 shows the PICkit™ Serial I
2
C™ Demo Board block diagram.
Pull-up resistors R2 and R3 are not populated. The PICkit Serial Analyzer can be
configured to enable internal pull-up resistors. When using the PICkit Serial Analyzer,
enable internal pull-up resistors. Or resistors R2 and R3 can be populated by the user
for use with other development boards or the PICkit Serial Analyzer internal pull-up
resistors disabled.
