GETTING STARTED WITH THE EXPLORER 16 DEVELOPMENT BOARD
This section describes how to use the MCP47X6 PICtail™ Plus Daughter Board with
the Explorer 16 Development Board.
the Explorer 16 Development Board.
After receiving the MCP47X6 PICtail™ Plus Daughter Board, program the 16-bit
PIC24FJ128 MCU on the Explorer 16 Starter Kit using the firmware provided. The user
can download the latest firmware from the Microchip website:

• Step 1: Insert the MCP47X6 PICtail™ Plus Daughter Board to the Explorer 16
Development Board. Figure 1-2 shows the configuration when the board is
connected to the Explorer 16 Development Board.
connected to the Explorer 16 Development Board.
• Step 2: Program the Explorer 16 Development Board using the firmware provided
with this board. Figure 1-3 shows the connection of the MPLAB ICD2 with the
Explorer 16 Development Board for programming.
Explorer 16 Development Board for programming.
• Step 3: Once the programming is done, disconnect the MPLAB ICD2 from the
Explorer 16 Development Board.
• Step 4: Now you can evaluate the performance of the DAC devices. The LCD on
the Explorer 16 Development Board will display instructions on how to select the
DAC device using the push button switches on the Development Board: (a) S3 for
MCP4726, (b) S6 for MCP4716, and (c) S5 for MCP4706. S4 is used to increment
the DAC code. If you hold down the S4 switch, the DAC code will increase
continuously until it reaches the maximum value, and then it starts from code 0
again. You can observe this event by simply connecting a voltmeter at the V
DAC device using the push button switches on the Development Board: (a) S3 for
MCP4726, (b) S6 for MCP4716, and (c) S5 for MCP4706. S4 is used to increment
the DAC code. If you hold down the S4 switch, the DAC code will increase
continuously until it reaches the maximum value, and then it starts from code 0
again. You can observe this event by simply connecting a voltmeter at the V
OUT
pin while holding down the S4 switch.
All procedures are very intuitive and interactive using the Push button switches and by
following the instructions on the LCD. The user can observe the DAC output (V

changes using an oscilloscope or voltmeter by pressing the S4 switch. The firmware
provided is an example that can be used as reference for the user’s applications.
