Getting Started Follow these steps to explore the Curiosity Pro platform: 1. 2. 3. Download MPLAB X IDE. Launch MPLAB X IDE. 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. © 2022 Microchip Technology Inc. and its subsidiaries User Guide DS70005443E-page 7 PIC32CM LE00/LS00/LS60 Curiosity Pro 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. © 2022 Microchip Technology Inc. and its subsidiaries User Guide DS70005443E-page 8 PIC32CM LE00/LS00/LS60 Curiosity Pro 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. © 2022 Microchip Technology Inc. and its subsidiaries User Guide DS70005443E-page 9 PIC32CM LE00/LS00/LS60 Curiosity Pro • 3.2.3 Clock sync: Synchronization signal to synchronize ADC measurements with EDBG. 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 highgain 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 lowgain stage 150 nA 1 LSB ±1% - Range 3 High-current shunt and highgain 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. © 2022 Microchip Technology Inc. and its subsidiaries User Guide DS70005443E-page 10 PIC32CM LE00/LS00/LS60 Hardware User Guide 4.

XAM MCU Current Measurement (J205) Jumper Setting Function 1-2 XAM is bypassed for the MCU 2-3 XAM is measuring the MCU current consumption On the Curiosity Pro, the XAM can be used in the following four configurations: • • • • No current measurement or external MCU current measurement: The XAM is bypassed, and the MCU and the on-board Peripherals/Components are supplied by the regulator. Set both the jumpers in the BYPASS position. In this configuration, users can connect external measurement tools on the Curiosity Pro MCU power measurement header to measure MCU current directly instead of using the XAM. MCU current measurement: The XAM measures only the MCU current while the on-board Peripherals/ Components are supplied by the regulator. For this configuration, place the jumper for the on-board Peripherals/ Components into the BYPASS position and the MCU into the MEASURE position. Peripherals measurement: The XAM measures only the current of the on-board Peripherals/Components while the MCU is supplied by the regulator. For this configuration place the jumper for MCU into the BYPASS position and the on-board Peripherals/Components jumper into the MEASURE position. MCU and peripherals measurement: In this configuration both the MCU and the on-board Peripherals/ Components are measured by the XAM. Place both the jumpers on the on-board Peripherals/Components and MCU headers in the MEASURE position. © 2022 Microchip Technology Inc. and its subsidiaries User Guide DS70005443E-page 24 PIC32CM LE00/LS00/LS60 Product Identifier and Revision 5.
