 +====== chipKIT Uno32 Hardware Description ======
 +
 +==== MPIDE and USB Serial Communications ====
 +
 +The Uno32 board is designed to be used with
 +the Multi-Platform IDE (MPIDE). Digilent
 +produced the MPIDE development platform by
 +modifying the Arduino™ IDE. It is backwardscompatible
 +with the Arduino IDE. 
 +
 +The MPIDE uses a serial communications port
 +to communicate with a boot loader running on
 +the Uno32 board. The serial port on the Uno32
 +board is implemented using an FTDI FT232R
 +USB serial converter. Before attempting to use
 +the MPIDE to communicate with the Uno32,
 +the appropriate USB device driver must be
 +installed. 
 +
 +The Uno32 board uses a standard mini-USB
 +connector for connection to a USB port on the
 +PC. 
 +
 +When the MPIDE needs to communicate with
 +the Uno32 board, the board is reset and starts
 +running the boot loader. The MPIDE then
 +establishes communications with the boot
 +loader and downloads the program to the
 +board.
 +
 +When the MPIDE opens the serial
 +communications connection on the PC, the
 +DTR pin on the FT232R chip is driven low.
 +This pin is coupled through a capacitor to the
 +MCLR pin on the PIC32 microcontroller.
 +Driving the MCLR line low resets the
 +microcontroller, restarting execution with the
 +boot loader.
 +
 +This automatic reset action (when the serial
 +communications connection is opened) can be
 +disabled. To disable this operation, there is a
 +cut-able trace on the bottom of the board
 +between the pins on JP1. JP1 is normally not
 +loaded. If the trace between the pins on JP1
 +has been cut, the automatic reset operation
 +can be restored by loading JP1 and inserting a
 +shorting block across it. 
 +
 +Two red LEDs (LD1 and LD2) will blink when
 +data is being sent or received between the
 +Uno32 and the PC over the serial connection.
 +
 +The header connector J3 provides access to
 +the other serial handshaking signals provided
 +by the FT232R. Connector J3 is not loaded at
 +the factory and can be installed by the user to
 +access these signals. 
 +
 +==== Power Supply ====
 +
 +The Uno32 is designed to be powered either
 +via USB or from an external power supply.
 +There is an automatic switch-over circuit that
 +causes the external supply to be used if both
 +supplies are present.
 +
 +The power supply section in the Uno32 uses
 +two voltage regulators. The first regulates the
 +external voltage to 5V to power the VCC5V0
 +bus. The second regulates the VCC5V0 bus to
 +3.3V to provide power to the VCC3V3 bus that
 +powers the PIC32 microcontroller.
 +
 +The 5V voltage regulator is normally an
 +NCP1117. The board is designed to be able to
 +also use an LM1117, but the NCP1117 is the
 +part normally used. The NCP1117 is rated for
 +an output current of 1A (the LM1117 is rated
 +for 800mA). The dropout voltage of the
 +NCP1117 is a maximum of 1.2V at the rated
 +output current (1.3V for the LM1117).
 +
 +There is a reverse polarity protection diode in
 +the external power supply circuit. Considering
 +the diode drop plus the forward drop across
 +the regulator, the minimum input voltage to the
 +regulator should be 7V to produce a reliable 5V
 +output. The absolute maximum input voltage of
 +both the NCP1117 and the LM1117 is 20V.
 +The recommended maximum operating
 +voltage is 15V.
 +
 +For input voltages above 9V, the regulator will
 +get extremely hot when drawing high currents.
 +Both the NCP1117 and the LM1117 have output short circuit protection and internal
 +thermal protection and will shut down
 +automatically to prevent damage.
 +
 +The 3.3V regulator is a Microchip MCP1725.
 +This regulator is rated for a maximum output
 +current of 500mA. The absolute maximum
 +input voltage for the MCP1725 is 6V. This
 +regulator has internal short circuit protection
 +and thermal protection. It will get noticeably
 +warm when the current consumed by the
 +VCC3V3 bus is close to the 500mA maximum.
 +
 +The 5V power bus, VCC5V0 can be powered
 +from one of three sources: 
 +  * the USB5V0 bus when the board is operating under USB power, 
 +  * the output of the on-board 5V regulator when operating from an external 7V-15V supply,
 +  * directly from the external supply when operating from a regulated 5V external supply with jumper JP2 in the BYP position. 
 +
 +Switch-over from USB power to external power
 +is done automatically and the external supply
 +will be used if both are present. 
 +
 +Jumper JP2 is used to route the external
 +power supply voltage through the on-board 5V
 +regulator or directly to the VCC5V0 bus,
 +bypassing the on-board 5V regulator.
 +Normally, JP2 is in the REG position. This
 +routes the external supply through the 5V
 +regulator. Operation from an externally
 +regulated 5V supply is provided by placing the
 +jumper in the BYP position. 
 +
 +The forward drop across the MCP1725 is
 +typically 210mV (350mV max) at 500mA
 +output. With JP2 in the BYP position, this will
 +allow correct operation of the 3.3V power
 +supply from an input voltage down to 3.5V.
 +This lets you power the board from batteries
 +and other lower voltage power sources. In that
 +case, the VCC5V0 power bus will not be
 +powered at 5V. 
 +
 +**Note:** When JP2 is in the BYP position, do not
 +apply more than 6V to the external power
 +input. This can destroy the 3.3V regulator and
 +possibly the PIC32 microcontroller as well.
 +
 +The PIC32 microcontroller is rated to use a
 +maximum of 75mA of current when operating
 +at 80Mhz. This allows up to 425mA from the
 +VCC3V3 bus and up to 925mA from the
 +VCC5V0 bus to power external devices.
 +
 +The POWER connector, J2, is used to power
 +shields connected to the Uno32 board. The
 +following pins are provided on this connector:
 +
 +**P32_RST** (pin 1): This connects to the MCLR
 +pin on the PIC32 microcontroller and can be
 +used to reset the PIC32.
 +
 +**VCC3V3** (pin 2): This routes the 3.3V power
 +bus to shields. This pin can provide ~425mA.
 +
 +**VCC5V0** (pin 3): This routes the 5V power
 +bus to shields. This pin can provide up to
 +~900mA to shields, however the total
 +provided by pins 2 and 3 shouldn’t exceed
 +925mA.
 +
 +**GND** (pin 4, 5): This provides a common
 +ground connection between the Uno32 and
 +the shields.
 +
 +**VIN** (pin 6): This connects to the voltage
 +provided at the external power supply
 +connector. This can be used to provide
 +unregulated input power to the shield. It can
 +also be used to power the Uno32 board from
 +the shield instead of from the external power
 +connector.  
 +
 +
 +----
 +
 +====== 5V Compatibility ======
 +
 +The PIC32 microcontroller operates at 3.3V.
 +The original Arduino boards operate at 5V as
 +do many Arduino shields.
 +
 +There are two issues to consider when dealing
 +with 5V compatibility for 3.3V logic. The first is
 +protection of 3.3V inputs from damage caused
 +by 5V signals. The second is whether the 3.3V
 +output is high enough to be recognized as a
 +logic high value by a 5V input.
 +
 +The digital I/O pins on the PIC32
 +microcontroller are 5V tolerant. The analog
 +capable I/O pins are not 5V tolerant. To
 +provide 5V tolerance on those pins, the Uno32
 +contains clamp diodes and current limiting
 +resistors to protect them from 5V input
 +voltages.
 +
 +The fact that all I/O pins are 5V tolerant means
 +that it is safe to apply 5V logic levels to any
 +pins on the board without risk of damaging the
 +PIC32 microcontroller.
 +
 +The minimum high-voltage output of the PIC32
 +microcontroller is rated at 2.4V when sourcing
 +12mA of current. When driving a high
 +impedance input (typical of CMOS logic) the
 +output high voltage will be close to 3.3V. Some
 +5V devices will recognize this voltage as a
 +logic high input, and some won’t. Many 5V
 +logic devices will work reliably with 3.3V inputs. 
 +
 +----
 +
 +====== Input/Output Connections ======
 +
 +The Uno32 board provides 42 of the I/O pins
 +from the PIC32 microcontroller to pins on the
 +input/output connectors J5, J6, and J7.
 +
 +The PIC32 microcontroller can source or sink a
 +maximum of 18mA on all digital I/O pins.
 +However, to keep the output voltage within the
 +specified voltage range (VOL 0.4V, VOH 2.4V)
 +the pin current must be restricted to +7/-12mA.
 +The maximum current that can be sourced or
 +sunk across all I/O pins simultaneously is +/-
 +200mA. The maximum voltage that can be
 +applied to any I/O pin is 5.5V. For more
 +detailed specifications, refer to the
 +PIC32MX3XX/4XX Data Sheet available from
 +the Microchip web site.
 +
 +Connectors J5 and J6 are 2x8 female pin
 +header connectors that provide digital I/O
 +signals. The outer row of pins (closer to the
 +board edge) corresponds to the I/O connector
 +pins on an Arduino Uno or Duemilanove board.
 +The inner row of pins provides access to the
 +extra I/O signals provided by the PIC32
 +microcontroller. 
 +
 +Connector J7 is a 2x6 female pin header
 +connector that provides access to the analog
 +input pins on the microcontroller. The outer row
 +of pins corresponds to the six analog pins on
 +an Arduino Uno or Duemilanove. The inner row
 +of pins are the additional I/O signals provided
 +by the PIC32 microcontroller. The analog pins
 +on J7 can also be used as digital I/O pins.
 +
 +The chipKIT/Arduino system uses logical pin
 +numbers to identify digital I/O pins on the
 +connectors. The logical pin numbers for the I/O
 +pins on the Uno32 are 0-43. These pin
 +numbers are labeled in the silk screen on the
 +board.
 +
 +Pin numbers 0-13 are the outer row of pins on
 +J6 and J5, from right to left. Pin numbers 14-19
 +are the outer row of pins on J7 from left to
 +right. Pins 20-25 are the inner row of pins on
 +J7 from left to right. Pin numbers 26-41 are the
 +inner row of pins on J6 and J5 from right to left.
 +Pin 42 is the pin labeled A on J5. This pin is
 +normally the reference voltage for the
 +microcontroller’s A/D converter, but can also
 +be used as a digital I/O pin.
 +
 +In addition to the connector pin, Pin 13 also
 +connects to the user LED LD4. Pin 43
 +connects to user LED LD5. Pin 43 pin does not
 +go to any connector.
 +
 +The analog inputs on connector J7 are
 +assigned pin numbers. The outer row of pins
 +on J7 are analog inputs A0-A5. The inner row
 +of pins are A6-A11. These pins are also
 +assigned digital pin numbers: A0-A5 are digital
 +pins 14-19, and A6-A11 are 20-25. 
 +
 +
 +----
 +
 +====== Peripheral I/O Functions  ======
 +
 +The PIC32 microcontroller on the Uno32 board provides a number of peripheral functions. The following peripherals are provided: 
 +
 +====UART port 1:==== Asynchronous serial port. Pin 0
 +(RX), Pin 1 (TX). These pins are connected to
 +I/O connector J6 and are also connected to the
 +FT232R USB serial converter. It is possible to
 +use these pins to connect to an external serial device when not using the USB serial
 +interface. This uses UART1 (U1RX, U1TX) on
 +the PIC32 microcontroller. 
 +
 +====UART port 2: ====
 +Asynchronous serial port. Pin 39
 +(RX), Pin 40 (TX). This uses UART2 (U2RX,
 +U2TX) on the PIC32 microcontroller.  
 +
 +==== SPI: ====
 +
 +Synchronous serial port. Pin 10 (SS), Pin
 +11 (MOSI), Pin 12 (MISO), Pin 13 (SCK). This
 +uses SPI2 (SS2, SDI2, SDO2, SCK2) on the
 +PIC32 microcontroller These signals also
 +appear on connector J8. 
 +
 +Jumpers JP5 and JP7 are used to select
 +whether the Uno32 operates as a Master
 +(transmit on MOSI, receive on MISO) or a
 +Slave (transmit on MISO, receive on MOSI)
 +device. The shorting blocks on JP5 and JP7
 +are normally placed in the Master position for
 +the Uno32 to function as an SPI master. 
 +
 +Jumper JP4 is used to select PWM output or
 +the SPI SS function on Pin 10. The shorting
 +block on JP4 should be in the RD4 position to
 +select PWM output. It should be in the RG9
 +position to select the SPI SS function.. JP4 will
 +normally be in the RD4 position. In general, the
 +only time it needs to be in the RG9 position is
 +when the Uno32 board is being used as an SPI
 +slave device. 
 +
 +==== I²C: ====
 +
 +Synchronous serial interface. The PIC32
 +microcontroller shares analog pins A4 and A5
 +with the two I²C signals SDA and SCL.
 +Jumpers JP6 and JP8 are used to select
 +whether the analog pin functions or the I²C pin functions are being used. The shorting blocks
 +are placed in the A4/A5 position to select the
 +analog input function or general digital I/O.
 +They are placed in the RG3/RG2 position to
 +use the pins for I²C operation. This uses I²C1
 +(SDA1, SCL1) on the PIC32 microcontroller. 
 +
 +**Note:**
 +
 +The I²C bus uses open collector drivers
 +to allow multiple devices to drive the bus
 +signals. This means that pull-up resistors must
 +be provided to supply the logic high state for
 +the signals. These pull-up resistors are not on
 +the Uno32 board and must be provided 
 +externally. The required resistance of the pullup
 +resistor to use depends on the total number
 +of devices on the bus, the length of wire, and
 +the clock speed being used. It essentially
 +depends on distributed capacitance on the
 +bus. The higher the distributed capacitance
 +and the faster the clock speed, the smaller the
 +resistance should be. Values typically used are
 +in the range of 2K to 10K ohms. 
 +
 +==== PWM: ====
 +
 +Pulse width modulated output. Pins 3
 +(OC1), 5 (OC2), 6 (OC3), 9 (OC4), and 10
 +(OC5). 
 +
 +
 +==== External Interrupts: ====
 +
 +Pin 38 (INT0), Pin 2
 +(INT1), Pin 7 (INT2), Pin 8 (INT3), Pin 35
 +(INT4) 
 +
 +==== User LEDs: ====
 +
 +Pin 13 (LD4), Pin 43 (LD5). Pin 13
 +is shared between a connector pin and the
 +LED. Pin 43 only goes to the LED and not any
 +connector pin. Driving the pin high turns the
 +LED on, driving it low turns it off. 
 +
 +====A/D Converter Reference:====
 +
 +Labeled A, the leftmost
 +outer pin on connector J5. This is used to
 +provide an external voltage reference to
 +determine the input voltage range of the
 +analog pins. The maximum voltage that can be
 +applied to this pin is 3.3V. This pin can also be
 +used as digital pin 42. 
 +
 +==== RTCC: ====
 +
 +Real Time Clock Calendar. The PIC32
 +microcontroller contains an RTCC circuit that
 +can be used to maintain time and date
 +information. The operation of the RTCC
 +requires a 32.768Khz frequency source.
 +Crystal X2 (not loaded), just above and to the
 +right of the PIC32 microcontroller IC, is
 +provided for you to solder a 32Khz watch
 +crystal. The Citizen CFS206-32.768KDZF-UB
 +crystal can be used in this location.
 +
 +==== RESET: ====
 +
 +The PIC32 microcontroller is reset by
 +bringing its MCLR pin low. The MCLR pin is
 +connected to the P32_RST net on the circuit
 +board. 
 +
 +As described earlier, reset of the PIC32
 +microcontroller can be initiated by the USB serial converter. The USB serial converter
 +brings the DTR pin low to reset the
 +microcontroller. Jumper JP1 can be used to
 +enable/disable the ability for the USB serial
 +converter to initiate a reset. 
 +
 +The P32_RST net is connected to pin 1 of
 +connector J2. This allows circuitry on a shield
 +to reset the microcontroller, or to ensure that
 +the circuitry on the shield is reset at the same
 +time as the microcontroller.
 +Connector J8 provides access to the SPI bus.
 +Pin 5 provides access to the SPI Slave Select
 +signal (SS).
 +
 +On Arduino boards, the corresponding
 +connector is also used as an in-system
 +programming connector as well as providing
 +access to some of the SPI signals. On Arduino
 +boards, pin 5 of this connector is connected to
 +the reset net.
 +
 +Some Arduino shields, notably, the Ethernet
 +shield, connect pin 5 to the reset net on pin 1
 +of connector J2. This causes the processor to
 +be reset each time an attempt is made to
 +access the SPI port. Jumper JP9 can be used
 +to break the connection between J8 pin 5 and
 +reset when using Arduino shields that make
 +this connection. JP9 has a cut-able trace on
 +the bottom of the board that can be cut to
 +break the connection between SPI SS and
 +reset. JP9 is not loaded at the factory. To
 +restore the connection, solder a two pin header
 +at the JP9 position and install a shorting block.
 +
 +A reset button is at the upper left corner of the
 +board. Pressing this button resets the PIC32
 +microcontroller. 
 +
 +
 +----
 +
 +====== Microchip Development Tool Compatibility ======
 +
 +In addition to being used with the MPIDE, the
 +Uno32 board can be used as a more traditional
 +microcontroller development board using
 +Microchip Development Tools.
 +
 +Unloaded connector JP3 on the left side of the
 +board is used to connect to a Microchip
 +development tool, such as the PICkit3™. The
 +holes for JP3 are staggered so that a standard
 +100-mil spaced 6-pin header can be press fit to
 +the board without the need to solder it in place.
 +Any Microchip development tool that supports
 +the PIC32 microcontroller family, and can be
 +connected via the same 6-pin interface as the
 +PICkit3, can be used.
 +
 +Typically, a right-angle male connector is used
 +in JP3 so that a PICkit3 can be attached
 +coplanar with the Uno32 board. The connector
 +can be loaded from the top, or it can be loaded
 +from the bottom. In either case the PICkit3 will
 +be upright (button and LEDs visible).
 +
 +If JP3 is loaded from the top, the PICkit3 will
 +interfere with the USB connector and the
 +external power connector. A short six-wire
 +cable can be used between the PICkit3 and
 +the Uno32. If JP3 is loaded from the bottom,
 +the PICkit3 won’t interfere with the USB and
 +external power connectors.
 +
 +The Digilent PICkit3 Programming Cable Kit
 +includes all necessary connectors and a cable
 +for connecting a PICkit3 to the Uno32.
 +The Microchip MPLAB® IDE or the MPLAB® X
 +IDE can be used to program and debug code
 +running on the Uno32 board. These programs
 +can be downloaded from the Microchip web
 +site.
 +
 +Using the Microchip development tools to
 +program the Uno32 board will cause the boot
 +loader to be erased. To use the board with the
 +MPIDE again, it is necessary to program the
 +boot loader back onto the board. The boot
 +loader source code and compiled image can
 +be found in the MPIDE software download. 
 +
 +----
 +
 +======Pinout Tables======
 +
 +The following tables give the relationship
 +between the chipKIT digital pin numbers, the
 +connector pin numbers and the microcontroller
 +pin numbers.
 +
 +In the following tables, columns labeled
 +chipKIT pin # refer to the digital pin number.
 +This is the value that is passed to the
 +pinMode(), digitalRead(), digitalWrite() and
 +other functions to refer to the pin.
 +
 +For most pins, this pin number will agree with
 +the pin number labeled on the board. For the
 +pins whose function can be switched using
 +jumpers, the pin number labeled on the board
 +is correct when the jumper is in the ‘normal’
 +position. 
 +
 +For example: The normal position for JP4 is
 +the RD4 position. The digital pin number for
 +the microcontroller signal RD4 is 10. With JP4
 +in the RD4 position, digital pin 10 is connected
 +to the pin labeled 10 on the board. The
 +alternate position for JP4 is the RG9 position.
 +The digital pin number for the microcontroller
 +signal RG9 is 44. With JP4 in the RG9
 +position, digital pin 44 is connected to the pin
 +labeled 10 on the board, and digital pin 10 is
 +not connected.
 +
 +The pin labeled 10 on the board is connected
 +to connector J5 pin 5. This is shown as J5-05
 +in the following tables. In the ‘Pinout Table by
 +Shield Connector Pin’ table below, J5-05 is
 +shown has being either chipKIT pin # 10 or 44.
 +J5-04 is connected to chipKIT pin # 10 when
 +JP4 is in the RD4 position and is connected to
 +chipKIT pin # 44 when in the RG9 position.
