2. Getting Started
Follow these steps to explore the evaluation kit platform:
1. Download MPLAB® X IDE.
2. Launch MPLAB X IDE.
3. Connect the DEBUG USB port on the evaluation kit to the computer using a USB cable (Standard-A to
Micro-B or Micro-AB).
Note: When the evaluation kit is connected to the computer for the first time, the operating system will install
the software driver. The driver file supports both 32-bit and 64-bit versions of Microsoft Windows XP®, Windows
Vista®,Windows 7®, Windows 8®, Windows 10®, and Windows Server 2012®.
When the evaluation kit is powered, the green power LED will glow and MPLAB X IDE will auto-detect the specific
Curiosity Pro evaluation kit and extension boards that are connected to it. MPLAB X IDE will present relevant
information, such as data sheets and kit documentation.
The kit landing page in MPLAB X IDE also has an option to launch MPLAB Harmony v3 example applications for the
kit.
The PIC32CM JH01 device is programmed and debugged by the on-board Embedded Debugger (EDBG), hence no
external programmer or debugger tool is required.
Note: Users can connect external debugger tools using the Cortex-M Debug connector.

3. Curiosity Pro
The PIC32CM JH01 Curiosity Pro evaluation kit is a user-friendly rapid prototyping platform. It is supported with
MPLAB X IDE and MPLAB Harmony v3 software development framework that comes with demonstration codes,
middleware, PLIBs, and drivers.
The Curiosity Pro evaluation kits support a wide range of extension boards which are connected through a set
of standardized headers and connectors. Each extension board has an identification (ID) chip to uniquely identify
which boards are connected to the Curiosity Pro evaluation kit. When an extension board is connected, some
relevant information, such as board features, supported interfaces, serial number, links to documentation, is read and
displayed on the MPLAB X IDE window.
3.1 Embedded Debugger
The PIC32CM JH01 Curiosity Pro evaluation kit contains the Microchip Embedded Debugger (EDBG) for on-board
debugging. The EDBG is a composite USB device of the following three interfaces:
• Debugger
• Virtual COM Port
• Data Gateway Interface (DGI)
Together with MPLAB X IDE, the EDBG debugger interface programs and debugs the microcontroller. On the
Curiosity Pro evaluation kit, the SWD interface is connected between the EDBG and the microcontroller.
The Virtual COM Port is connected to a UART on the PIC32CM JH01 and provides an easy way to communicate with
the target application through terminal software. It offers variable baud rate, parity, and stop bit settings. The settings
on the PIC32CM JH01 must match the settings given in the terminal software.
Note: The virtual COM port in the EDBG requires the terminal software to set the data terminal ready (DTR) signal
to enable the UART pins connected to the PIC32CM JH01. If the DTR signal is not enabled, the UART pins on the
EDBG are kept in high-z (tristate) rendering the COM port unusable. The DTR signal is set automatically by some
terminal software, but it may have to be manually enabled in your terminal.
The DGI consists of several physical interfaces for communication with the Host computer. Communication over
the interfaces is bidirectional. It can be used to send events and values from the PIC32CM JH01. Traffic over the
interfaces can be timestamped by the EDBG for accurate tracing of events. time stamping imposes an overhead that
reduces maximal throughput. The MPLAB Data Visualizer is used to send and receive data through DGI.
The EDBG controls two LEDs: a power LED and a status LED. The following table provides how LEDs are controlled
in different operation modes.
Table 3-1. EDBG LED Control
Operation mode Power LED Status LED
Normal operation Power LED is lit when power is applied
to the kit.
Activity indicator, LED flashes when any
communication happens to the EDBG.
Bootloader mode (idle) The power LED and the status LED blink simultaneously.
Bootloader mode
(firmware upgrade) The power LED and the status LED blink in an alternating pattern.
For additional information on the EDBG, refer to the Microchip EDBG User Guide.

4.1 Power Sources
The PIC32CM JH01 Curiosity Pro evaluation kit can be powered by the following power sources:
• Embedded Debugger USB
• An external power
Table 4-1. Power Sources
Power input Voltage requirements Current requirements Connector
marking
External power 4.3V to 5.5V. Recommended maximum is 2A due to
the input protection maximum current
specification.
PWR
Embedded
debugger USB
4.4V to 5.25V (according to
USB spec.)
500 mA (according to USB spec.) DEBUG USB
The evaluation kit will automatically detect which power source is available, and choose which one to use according
to the following priority:
• External power
• Embedded Debugger USB
Note: External power is required when 500 mA from a USB connector is not enough to power the evaluation kit with
possible extension boards.
The EDBG controls an on-board power switch to the PIC32CM JH01, on-board peripherals, and extension
connectors. When the kit is powered up, the EDBG reads the ID chip information from all connected extension
boards and checks they are compatible with the voltage selected by the power selection jumper. If the selected
voltage is within the connected extensions ranges, the switch will open. If not, the EDBG power LED will blink rapidly
and the switch will stay closed resulting in no power provided to the PIC32CM JH01, on-board peripherals, and
connectors.
CAUTION
The evaluation kit can be powered by 5.0V. Care must be taken not to connect any extension board that
does not support this voltage, as it might results in permanent damage. Check the respective extension
kit's user guide to see which voltages are acceptable.
Remember: The EDBG only reads the ID information and controls the power switch when the kit is
powered up. This mechanism does not check hot plugging of extension boards.

4.2.2 Arduino Uno™ Header Connectors
The PIC32CM JH01 Curiosity Pro evaluation kit implements Arduino shield connectors based on the Arduino Uno. All
references to the Arduino pin names are taken from the official Arduino schematics of the Arduino Uno.
CAUTION
The target section of the evaluation kit can be powered by 3.3V or 5.0V. The maximum voltage to the I/O
pins can tolerate depends on the supply voltage. Providing higher voltages, such as 5V to an I/O pin, when
the PIC32CM JH01 is powered by 3.3V can damage the kit.
Remember: All pins do not have the same functionality on the Arduino Uno as on the shield connectors.
Each shield should be checked for compatibility before it is connected.

4.2.4 VCC Selection Header
The evaluation kit has a 3-pin header, labeled VCC_SEL. This header can be used to select between 3.3V and 5.0V
as the supply voltage for the PIC32CM JH01, peripherals, and extension headers by placing a jumper on the pin 1-2
or pin 2-3. Selecting 5.0V will supply the kit directly from the USB connector, or an external 5.0V source. Selecting
3.3V will supply the kit from an on-board regulator.

4.2.7 Current Measurement Header
An angled 1x2, 100 mil pin-header labeled CURRENT MEASURE is located at the upper edge of the evaluation kit.
All power to the PIC32CM JH01 is routed through this header. To measure the power consumption of the device,
remove the jumper and replace it with an ammeter.
CAUTION
Removing the jumper from the pin-header while the evaluation kit is powered may cause the PIC32CM
JH01 to be powered through its I/O pins. This may cause permanent damage to the device.
4.2.8 Cortex Debug Connector
The evaluation kit has a 10-pin 50-mil Cortex® Debug Connector that can be used to attach external debuggers to
the PIC32CM JH01.
