1.3.1
1. Connect the MCP4725 PICtail™ Plus Daughter Board to the J5 socket on the
FIGURE 1-2:
Explorer 16 Development Board.
1.3.2
The Explorer 16 Development Board contains the PIC24FJ128 MCU. The user can
download the firmware to the MCU using the MPLAB ICD2 programmer. Refer to
Chapter 2 of the Explorer 16 Development Board User’s Guide (DS51589) for details
on the programming of the Explorer 16 Development Board.
1.3.2.1
The original firmware for the Explorer 16 Development Board is modified for the
MCP4725 PICtail™ Plus Daughter Board demonstration. The firmware uses most of
the original codes for the Explorer 16 Development Board except the I
control routines for the PIC24FJ128 MCU.
The following four routines are added or modified from the original Explorer 16 Devel-
opment Board firmware.
• PIC24ExplDemo_MCP4725_Main.c
• MCP4725_i2C_Func.c
• Banner_MCP4725.c
• i2C_MCP4725.h
The user can modify the above routines for their own application.
The source code is compiled by using Microchip’s C30 Compiler and the hex code is
programmed to the MCU using the MPLAB ICD 2. Figure 1-3 shows connection of the
MPLAB ICD 2 and the Explorer 16 Development Board. Figure 1-4 shows the MPLAB
IDE programming environment.
