4.1.10
The power supply furnishes +5V or +3.3V for the board (see the schematic in
Figure A-4). Source power is provided by a +9V, AC/DC wall adapter through Diode
Bridge CR1. An LM317 voltage regulator provides power (V
respective processor pins and prototyping area. A ground trace connects all V
points.
4.1.11
A red LED (D1) indicates the presence of power (see Figure A-4).
4.1.12
The board provides two crystal oscillators. Y1 operates at 7.37 kHz, and Y2 operates
at 32.768 kHz. A socket is provided for an external oscillator (Y3). The oscillator circuits
are shown in Figure A-4.
4.1.13
The MCLR Reset switch (S3) connected to the processor MCLR pin provides a hard
reset to the dsPIC DSC or PIC24 MCU device.
4.1.14
A prototyping area and associated header is provided which enables additional ICs and
attachment boards to be added.
4.1.15
A sample part programmed with the demonstration code is included in the dsPICDEM
80-Pin Starter Development Board kit. The 80-pin TQFP is soldered onto an adapter
board that plugs into the device header connection (see Figure 4-2).
4.1.16
Pins provide line input and output connections for the low-pass filter, as shown in
Figure A-6.
• LINE_OUT – Output signal from digital potentiometer
• LINE_IN – Input signal for ADC
4.1.17
An input jack for 9V external power supply.
