Appendix A. Hardware Detail
The PICDEM 2 hardware is extremely simple and is intended to illustrate the
ease of use of various PICmicro MCUs. The PICDEM 2 features the following
hardware elements:
A.1
Processor Sockets
Although two sockets are provided, only one device may be used at a time.
40-pin socket
28-pin socket
A.2
Display
Eight red LEDs are connected to PORTB of each processor type. The
PORTB pins are set high to light the LEDs. These LEDs may be disconnected
from PORTB by removing jumper J6.
One green LED is provided to determine whether there is power to the
PICDEM 2 board (LED lit) or not (LED off).
A.3
Power Supply
There are three ways to supply power to PICDEM 2:
A 9V battery can be plugged into J8.
A 9V, 100mA unregulated AC or DC supply can be plugged into J2.
A +5V, 100mA regulated DC supply can be connected to the hooks
provided.
In-circuit emulator users have a regulated +5V power supply available in the
logic probe connector and can easily connect to the hooks on PICDEM 2 (Red
probe to +5V and Black probe to GND).
Note 1:
The exact power up sequence listed in Getting Started
(Chapter 2) of this guide must be followed.
2:
The PICDEM 2 kit does not provide a power supply.
