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

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.
