PIC32CM LE00/LS00/LS60 Curiosity Pro User Guide
Preface
The Microchip® PIC32CM LE00, PIC32CM LS00, and PIC32CM LS60 Curiosity Pro evaluation kits are hardware
platforms for evaluating the PIC32CM LE00/LS00/LS60 microcontrollers (MCUs). Each evaluation kit is supported by
the MPLAB® X Integrated Development Environment (IDE) and MPLAB Harmony v3 featuring application examples.
The Curiosity Pro evaluation kits include an on-board embedded debugger to program or debug the target
microcontroller. This enables an easy start to a project, and provides application examples that can be used in
the design of a custom application.
The Curiosity Pro evaluation kits provide easy access to the features of the microcontroller, and are integrated
with Arduino Uno, mikroBUS™, and extension headers to interface with Xplained Pro extension boards for a rapid
prototyping and expanded functionality.

2. Getting Started
Follow these steps to explore the Curiosity Pro platform:
1. Download MPLAB X IDE.
2. Launch MPLAB X IDE.
3. Connect the DEBUG USB port on the kit to the computer using a USB cable (Standard-A to Micro-B, or
Micro-AB).
Note: When the Curiosity Pro MCU kit is connected to the computer for the first time, the operating system will
install the software driver. The software driver supports both 32-bit and 64-bit versions of Microsoft® Windows®XP,
Windows Vista®, Windows 7, Windows 8, and Windows 10.
When the Curiosity Pro MCU board is powered, the power LED (green) will glow and MPLAB X IDE will auto-detect
the specific Curiosity Pro MCU and extension boards that are connected to it. MPLAB X IDE will present relevant
information, such as data sheets and kit documentation.
The PIC32CM LE00/LS00/LS60 devices can be programmed and debugged by the on-board embedded debugger
(EDBG), hence external programmer or debugger tool is not required.
Note: Users can connect external debugger tools using the Cortex-M Debugger or the PICkit™ 4 Interface headers.

3. Curiosity Pro
The Curiosity Pro 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, and so on is read
and displayed on the MPLAB X IDE kit window.
3.1 Embedded Debugger
The Curiosity Pro contains Embedded Debugger (EDBG) for on-board debugging. The EDBG is a USB composite
device with the following interfaces:
• Debugger (SWD)
• Virtual COM port (CDC)
• Data gateway interface (DGI)
Together with MPLAB X IDE the EDBG debugger interface can program and debug the microcontroller. On
the PIC32CM LE00/LS00/LS60 Curiosity Pro, the SWD interface is connected between the EDBG and the
microcontroller.
The virtual COM Port is connected to a UART on the microcontroller and provides a straight forward way to
communicate with the target application through terminal software. It offers variable baud rate, parity, and stop bit
settings. The settings on the microcontroller 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 microcontroller. If the DTR signal is not enabled, the UART pins on the
EDBG is kept in High-Z (tristate), rendering the COM port unusable. The DTR signal is set automatically by some
terminal software, but it must be manually enabled in the 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 microcontroller or as a generic
printf-style data channel. Traffic over the interfaces can be time stamped on the EDBG for accurate tracing of events.
Timestamping imposes an overhead that reduces maximum throughput. The MPLAB Data Visualizer Extension,
installed with MPLAB X IDE, is used to send and receive data through the DGI.
The EDBG controls two LEDs on the PIC32CM LE00/LS00/LS60 Curiosity Pro: a power LED and a status LED. The
following table provides how the 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 board.
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 EDBG, refer to the Microchip EDBG User Guide.

3.2 Curiosity Pro Embedded Current Measurement Circuitry (XAM)
3.2.1 Overview
The Curiosity Pro Embedded Current Measurement Circuitry (XAM) extends the embedded debugger with high
dynamic range current measurement, and this enables the power profiling of the target system.
Figure 3-1. Curiosity Pro Embedded Current Measurement Circuitry (XAM)
The following are key features of the XAM:
• Calibration circuitry
• Voltage reference
• Analog front end
– Shunt resistors with a range selection switch
– Preamplifier
– Two active filters with gain
• Control MCU
– Analog-to-Digital Converter (ADC)
– Signal processing
– Control or communication interface to the EDBG
The current measurement front end is a high-side shunt measurement with a preamplifier, and a second active filter
stage with gain. The wide dynamic range is achieved by four measurement ranges which are defined by two shunts,
and the two parallel second stage active filters with gain.
3.2.2 EDBG Interface
The Curiosity Pro Embedded Current Measurement Circuitry (XAM) is connected to the EDBG with the following
interfaces:
• I2C: Used to control and configure the XAM.
• SPI: Current measurement data is streamed to the EDBG through this interface. This is a one-way data transfer
channel from the XAM to the EDBG.
• SWD: The MCU in the XAM is programmed through SWD from the EDBG.
• GPIO: At least one GPIO that is connected to the EDBG from the target MCU is also connected to the current
measurement unit to enable the user to sync current measurements with their application.

• Clock sync: Synchronization signal to synchronize ADC measurements with EDBG.
3.2.3 Measurement Ranges and Accuracy
The XAM has the following four measurement ranges, which are defined by two shunt resistors and two gain stages
as provided in the table below:
Table 3-2. XAM Measurement Ranges and Accuracy
Measurement
Range Hardware Resolution Accuracy Comments
Range 1 Low-current shunt and high-
gain stage
20 nA 1 LSB ±1% Below 1 µA the error will increase.
Typical error for 300 nA is 1 LSB
±10%
Range 2 Low-current shunt and low-
gain stage
150 nA 1 LSB ±1% -
Range 3 High-current shunt and high-
gain stage
10 μA 1 LSB ±1% -
Range 4 High current shunt and low
gain stage
100 μA 1 LSB ±1% Above 100 mA the error will
increase to 1 LSB ±5% at 400 mA.
Maximum current is 400 mA
The ranges are switched automatically by the XAM to achieve best measurement results and the current active range
is visualized in the MPLAB Data Visualizer front end tool. The maximum voltage drops over the shunt resistor is 100
mV, and the XAM will switch the range automatically before this limit is reached.
