Installation and Operation
2.4
RUNNING THE DEMOS
The Mixed Signal PICtail? Demo Board was designed to utilize the PIC16F767
located on the PCB or a PICmicro microcontroller operating on the PICkit? 1 Flash
Starter Kit board. This Mixed Signal PICtail? Demo Board User ’s Guide will only
discuss the stand-alone operation utilizing the PIC16F767.
2.4.1
Power
The Mixed Signal PICtail? Demo Board can be powered by either the PICkit? 1 Flash
Starter Kit’s V DD and V SS signals or by a DC power supply 9V (5V minimum and 10V
maximum). The onboard TC55 5.0V LDO produces a regulated 5.0V supply to operate
the analog devices under test. The Mixed Signal PICtail? Demo Board User ’s Guide
assumes the standard 9V power supply that comes with many of Microchip’s develop-
ment tools (including the MPLAB ? ICD 2) is utilized. The standard 9V DC connector is
provided for your convenience.
With the default firmware programmed into the PIC16F767, the LED’s should
alternately flash for approximately two seconds upon power-up.
2.4.2
Selecting the Mode
S 1 is a 4-position DIP switch numerically labeled 1, 2, 3 and 4. These contact switches
have one terminal tied to V SS and one terminal connected to a 1 k ? resister in series
with the PIC16F767 PORTB<4:7> I/O port. These pins have an internal weak pull-up
to prevent the I/O from floating when the corresponding DIP switch is open. The DIP
switch is labeled with an arrow indicating the “on” (or closed) position of the switch.
When the DIP switch is on, the I/O pin is pulled down to V SS . The default firmware will
interpret this as a “ 0 ”. The binary combination of these four DIP switches determine the
mode of operation.
Note:
Selecting the mode requires the user to not “read” the switches as a binary
number. Switch 1 is on the left, while switch 4 is on the right. Typically, the
most significant digit is on the left, unlike this configuration. In addition, the
“on” position represents a “ 0 ”, which is also counterintuitive. The user could
alter the default firmware to interpret the mode switches differently (change
the jump table’s order) or simply look at the board with the 14-pin header
located at the top.
Refer to Section 2.3.2 “The Embedded System Firmware” for operational details for
each mode.
2.4.3
Jumper JP1 Selection
Jumper JP1 is located in the center of the board closest to the PICmicro microcontroller
and its MPLAB ICD 2 connector. JP1 consists of three pairs of jumper pins. The
lower-two pins are connected to A IN_C . The two center pins are connected to V OUTC .
The top-two pins are connected to A IN_D .
If the user would like to read the output of Microchip’s TC132X DAC using either the
MCP3302 or MCP3204, place a jumper from one of the middle two pins to either of the
outer pins, depending on which ADC input channel you are using.
Note:
? 2004 Microchip Technology Inc.
The default firmware Mode1101 requires JP1 to be connected to A IN_C .
