For the home made tool, cut two pieces of wire coat hanger about 8" long each and bend them both into a "U" shape. On the left and right sides of units, their are two rubber plugs. Remove the four rubber plugs. Place the Radio Puller Tool or your home made "U" shaped pieces of coat hanger into these holes. When inserting in the holes be sure to angle the ends towards the outside of the car to catch the clips.

Once they have been inserted about an inch you should feel some pressure on them. This is because they are disengaging the springs holding the unit in place. Now while pushing the puller tool handles towards the outside of the car, simply pull the unit out from the dash, being sure not to pull any wires to hard. Unplug any harnesses or wires attached to the back of the unit, making sure not to lose them in behind the dash.

It will get noticeably warm when the current consumed by the VCC3V3 bus is close to the mA maximum.

Switchover 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. This routes the external supply through the 5V regulator. Operation from an externally regulated 5V supply is accomplished by placing the jumper in the BYP position. This allows powering the board from batteries and other lower voltage power sources.

Applying more than 6V to the external power input with the jumper in the BYP position can damage the 3. Each Pmod connector provides power pins that can be powered from either the switched main power bus, VCC5V0, or the regulated voltage, VCC3V3, by setting the voltage jumper block to the desired position.

When powering the board from a Pmod connector with the power select jumper in the 5V0 position, a voltage applied at the Pmod connector will power the VCC5V0 bus and be regulated to 3. A reset button is at the upper left corner of the board. Pressing this button will reset the PIC32 microcontroller.

The MX3 has five connectors for connecting Digilent Pmod peripheral modules. The Pmod product line includes such things as button, switch and LED modules, connector modules, LCD displays, high current output drivers, and many others. There are two styles of Pmod connector: six-pin and twelve-pin. Both connectors use standard pin headers with mil spaced pins. All of the Pmod connectors on the MX3 are twelve pin connectors. The twelve-pin connectors have the signals arranged so that one twelve-pin connector is equivalent to two of the six-pin connectors.

The pin numbering that Digilent uses on the twelve-pin Pmod connectors is non-standard. The upper row of pins are numbered 1—6, left to right when viewed from the top of the board , and the lower row of pins are numbered 7—12, left to right. This is in keeping with the convention that the upper and lower rows of pins can be considered to be two six-pin connectors stacked.

When viewed from the end of the connector, pin 1 is the upper right pin and pin 7 is immediately below it closer to the PCB. Each Pmod connector has an associated power select jumper. These are used to select the power supply voltage supplied to the power supply pin on the Pmod connector. They are switchable between either the regulated 5V power supply or the 3. Place the shorting block in the 3V3 position for regulated 3. Note that the 5V0 position will supply the unregulated input supply if the regulator bypass jumper JP2 is in the BYP position.

Each pin has a ohm series resistor and an ESD protection diode. Although ESD protection is provided between the connector pins and the microcontroller pins, ESD safe handling procedures should be followed when handling the circuit board. The pins on the microcontroller and other circuits on the board are exposed and can be damaged through ESD when handling the board. Digilent Pmod peripheral modules can either be plugged directly into the connectors on the MX3 or attached via cables.

Digilent has a variety of Pmod interconnect cables available. These tables indicate the mapping between pins on the PIC32MX microcontroller and the pins on the various connectors. Any of the pins on the Pmod or I2C connectors can be individually accessed for digital input or output.

The TRIS register is used to set the pin direction. Setting a TRIS bit to 0 makes the pin an output. Setting the TRIS bit to 1 makes the pin an input. Writing to the LAT register sets any pins configured as outputs. Reading from the LAT register returns the last value written. PIC32 microcontrollers allow any pin set as an output to be configured as either a normal totem-pole output or as an open-drain output.

The ODC register is used to control the output type. Setting an ODC bit to 0 makes the pin a normal output and setting it to 1 makes the pin an open drain output. These pin numbers start with pin 0 and are numbered up consecutively. On the MX3, pin numbers 0—39 are used to access the pins on the Pmod connectors and pin numbers 40 and 41 are used for the two signal pins on the I2C connector.

Refer to the tables in Appendices B—D for detailed information about the pin mapping between Pmod connector, logical pin number, and PIC32 microcontroller pin number and pin function. The pinMode function is used to set the pin direction.

OPEN is used for open-drain and implies output. The digitalRead and digitalWrite functions are used to read or write the pins. DigitalRead returns the current state of the specified pin, and digitalWrite is used to set the state of an output pin. The LEDs are turned on or off by configuring these two pins as outputs and driving them high or low.
