Overview

---

The PIC32CM JH01 Curiosity Nano+ Touch Evaluation Kit (EV29G58A) is a hardware platform that contains a PIC32CM5164JH01048 microcontroller (MCU). The Curiosity Nano+ Touch Evaluation Kit provides easy access to the MCU features and can develop custom applications.

Hardware

---

• PIC32CM5164JH01048 MCU

• Arm® Cortex®-M0+ based MCU

• One yellow user LED

• One mechanical user switch

• One user touch button

• CAN interface

• LIN interface

• USB for debugger

  • Can be used for powering the board
  • Must be used to program, or debug, the board

• On-board nano debugger (nEDBG)

  • One green power/status LED
  • Programming and debugging
  • Communications Device Class (CDC) virtual COM port
  • One logic analyzer DGI GPIO
  • The target device is programmed and debugged by the on-board Nano debugger; no external programmer, or debugging tool, is required

• Adjustable target voltage

  • MIC5353 LDO regulator controlled by the on-board debugger
  • 1.7V to 3.6V output voltage
  • 500-mA maximum output current (limited by ambient temperature and output voltage)

Setting Up the Debug Interface

PyOCD Setup

1. Install Device Pack

   • Add support for the PIC32CM family devices using the following command:

     .. code-block:: console

     pyocd pack install pic32cm

2. Verify Device Support

   • Confirm that the target is recognized:

     .. code-block:: console

     pyocd list --targets

   • You should see an entry similar to:

     .. code-block:: text

     pic32cm5164jh01048 Microchip PIC32CM5164JH01048 PIC32CM-JH pack

3. Connect the Board

   • Connect the DEBUG USB(J18) port on the board to your host machine.
   • This connection power up the board and provides access to the on-board Embedded Debugger (EDBG), which enables programming and debugging of the target microcontroller through PyOCD.

Building and Flashing the Application

1. Build the Application

   You can build a sample Zephyr application, such as Blinky, using the west tool. Run the following commands from your Zephyr workspace:

   .. code-block:: console

   west build -b pic32cm_jh01_cnano -p -s samples/basic/blinky

   This will build the Blinky application for the pic32cm_jh01_cnano board.

2. Flash the Device

   Once the build completes, flash the firmware using:

   .. code-block:: console

   west flash

3. Observe the Result

   After flashing, LED1 on the board should start blinking, indicating that the application is running successfully.
