Introduction to the PICDEM? FS USB Board
3. Oscillator: The demonstration board uses a 20 MHz crystal oscillator (Y1) as
the primary clock service. The PIC18F4550 uses this oscillator to generate the
necessary clock signals for both the USB Serial Interface Engine (SIE) and the
core processor.
4. ICD Configuration Jumpers: These three unpopulated jumper positions allow
the user to choose either legacy or dedicated ICSP? and ICD ports for the
controller. By default, the board is hard-configured for the legacy port. The
5. Expansion and PICtail Daughter Board Headers: The pads at J6 and J7 are
provided for users to install the header and directly access the microcontroller’s
I/O port signals. In addition, the 14 even numbered pins of J6 (those on the right
side as viewed from the top) serve as the interface for Microchip’s PICtail
daughter boards. This allows the PICDEM FS USB board to be used as a test
platform and USB communications interface for the PICtail daughter boards.
6. Configuration Jumpers: A total of 13 unpopulated jumper positions are
provided across the board; these allow users to modify the board by configuring
its hardware to suit their needs. By default, all jumpers are bridged and all
features are enabled. The configuration and use of these jumpers is detailed in
7. Potentiometer: The potentiometer (R20) simulates an analog input for the
controller. Its real-time value can also displayed by the Demo Tool host software.
8. Temperature Sensor: A Microchip TC77 digital temperature sensor (U4)
continuously monitors the board’s ambient temperature. Data is transmitted to
the controller via a 3-wire SPI interface, and is displayed in real time by the Demo
Tool software.
9. Power LEDs (Green): These light to show that power is being supplied to the
board, and to indicate how the board is being powered. LED D7 indicates that
the board is being powered from the bus, while D8 indicates the board is being
powered from a separate power supply.
10. Reset Pushbutton: This switch (S1) is tied to the MCLR pin of the PIC18F4550
controller; pressing it causes a hard device Reset.
11. Power Connector: Power (9 V DC ) can be supplied to the board from an external
power adapter through a mini barrel jack. Using an external supply is optional,
as all examples provided with the demonstration board can use power from the
USB cable.
12. USB Connector: This is a standard USB series “B” receptacle. The USB port is
the primary channel for controlling and communicating with the demonstration
board.
13. ICD Connector: This 6-wire RJ11 connector provides the standard interface
used by Microchip development and demonstration boards for programming and
debugging applications, using MPLAB ICD 2 and other development tools.
14. Status LED Bank: A bank of four green LEDs is used to show the operational
status of the board. Two LEDs (D1 and D2) are used by the application firmware
to indicate the status of the USB connection. The other LEDs (D3 and D4) can be
defined by the user; they are directly controllable through the Demo Tool software.
15. User-Defined Pushbuttons: These two switches (S2 and S3) are provided to
simulate digital control inputs. Pressing either button causes its port to read
as ‘ 0 ’.
16. RS-232 (DB9F) Port: A standard D-shell connector, along with a standard level
shifter (U1), provides an RS-232 serial connection to the demonstration board.
