PICDEM™ LCD 2 DEMONSTRATION
KIT USER’S GUIDE
2010 Microchip Technology Inc. DS51662C-page 15
Chapter 2. Getting Started
The PICDEM LCD 2 may be used as a stand-alone board with a preprogrammed
device, with an In-Circuit Emulator (ICE) or with an In-Circuit Debugger (ICD). For a list
of PIC
®
microcontroller compatible ICEs or ICDs, please refer to the “Microchip
Development Systems Ordering Guide” (DS30177).
2.1 PICDEM LCD 2 AS A STAND-ALONE BOARD – PREPROGRAMMED DEVICE
The PICDEM LCD 2 may be demonstrated immediately by following the steps listed
below:
• Apply power to the PICDEM LCD 2. For information on acceptable power
sources, see Appendix A. “Board Technical Information”.
To reprogram the sample device, the following will be necessary:
1. User source code may be programmed to the device or the sample program may
be restored from the file on the included CD-ROM.
2. An assembler, such as the MPASM™ Assembler (available with MPLAB IDE), or
a compiler, such as MPLAB C18 C Compiler (PIC18XXXX/18XXJXX devices
only) must be used.
Source code must be assembled or compiled into a HEX file before it can be
programmed into the device. Microchip Technology’s MPASM Assembler or
MPLAB C18 C Compiler may be used. Both are compatible with MPLAB IDE;
however, other assemblers/compilers may be used.
3. Once the sample program is in the HEX file format, it can be programmed to a
Flash device using an MPLAB ICD 2 or PM3 with an ICSP™ module. Microchip
Technology’s MPLAB ICD 2 is compatible with MPLAB IDE.
If the code protection bit(s) have not been programmed, the on-chip program
memory can be read out for verification purposes.
Note: In the event that the preprogrammed PICDEM LCD 2 Demonstration Board
with the PIC18F85J90 PIM does not operate, check the following
conditions:
- The jumper, J15, is configured as per the power supply used. The slide
switch, S6, is switched to C.
- JP1, JP2, JP6, JP18 and JP19 are connected.
- The middle two jumpers of J14 are connected.
- JP9 and JP10 are connected.
- J11 connecting POT to AN0 and JP17 connecting V
CC to I/O.
The status of all other jumpers will not affect the preprogrammed
demonstration.
