Summary
The PICDEM™ System Management Kit is a demonstration
and training tool designed for individuals interested in
system integration and design of a variety of applications.
PIC® microcontrollers provide a wide variety of integrated
peripherals ideally suited for these tasks.
System integration refers to the consolidation of multiple
systems into a single system. The PICDEM System
Management Board provides an I
typically found in applications, such as personal computers
or rack mount servers. The bus connects to multiple devices
used to monitor and record the health and status of a
computer system. The PICDEM System Management Board
integrates the functions of a dedicated Real-Time Clock
(RTC), serial EEPROM, thermal management controller and
analog-to-digital converter into a single PIC microcontroller.
In conjunction with the PICkit™ Serial Analyzer (included in
the kit), communication to the emulated devices on the bus
can be managed and monitored. The PICkit Serial Analyzer
is a low-cost development tool that allows communication
between a PC and the serial protocol of the system under
test.
