5.7 COMMUNICATIONS: PROFILE GENERATOR
The I
2
C Slave Profile Generator allows you to mimic an I
2
C slave device from either
the PICkit Serial Analyzer PC interface, or from the PICkit Serial Analyzer itself. The
trade-off between the two methods is flexibility vs. response time. Mimicking a device
from the PC allows for a great deal of run time flexibility, while running from the PICkit
Serial Analyzer decreases response time. You can mimic up to eight registers in a
profile.

CREATING A PROFILE
Create a profile by filling in Inputs for each register:
• Active – Allows you to activate or deactivate a register. This must be active before
you can fill in the rest of the data. The purpose of this checkbox is to allow run
time activation or deactivation of a register.
• Comm – Flashes when the register is activated (read from or written to).
• Slave Address – Hex representation of the register’s slave address.
• Register Name – Enter a register name. This is for reference only and does not
affect operation.
• Word Address – Hex representation of the word address of the register (will be
forced to zero if Memory Block is selected.
• Enable Read – Determines whether or not the register is read accessible.
• Enable Write – Determines whether or not the register is write accessible.
Note: The Basic Operations page and the Profile Generator page cannot both be
opened at the same time due to DLL conflict issues.
