The reasons for requiring you to use the provided jumpers to connect components to
the microcontroller are three-fold.
1. You will gain knowledge and experience by physically connecting components to
the microcontroller.
2. There are more peripherals than pins on the microcontrollers so that you can do
more with the board.
3. Should you choose to use the board to experiment on your own, the board allows
you the flexibility to do so. You can try experimenting with peripherals not
covered in the projects in Chapter 2. “Example Projects”.
1.6 REQUIRED TOOLS
One of the following programming tools is needed in order to complete the projects in
the next chapter:
PICkit™ 2 Microcontroller Programmer (Part# DV164120)
MPLAB
®
ICD 2 In-Circuit Debugger/Programmer (Part# DV164007 includes a
9V
DC power supply and serial cable)
Figures 1-3 and 1-4 illustrate how to connect each of these tools to the PICDEM
Mechatronics Demo Board.
1.7 PICDEM™ MECHATRONICS SETUP
Please take a moment to review the following steps, prior to using the board. These
steps ensure the board is configured correctly before beginning the projects.
1.7.1 Jumper Settings
Remove all 2-pin shunts (jumpers), except for JP8. On JP8, the shunt should be
connected in the right most position (indicated by the “+5V” label), which ensures that
the drive stage is powered by +5 V
DC.
1.7.2 Board Power-Up
Supply power to the board in one of the following ways:
Connect a 9-12 V
DC (0.75 amp minimum) supply via J9. The connector’s polarity
is grounded externally and positive internally.
Connect a 9-12 V
DC (0.75 amp minimum) supply to the P21 and P20 screw
terminals.
Connect a 9 V
DC battery to the battery connector.
Connect a 5 VDC (1.2 amp minimum) supply to TP2 or TP3.
When power is initially connected, the “PWR ON” LED should light up. The “FAULT”
LED in the over-current sense circuit will also be on when the board is powered up.
Clear the Fault by pressing SW5 (CLR FAULT) switch. The board is now properly
configured for the projects.
