This is a X2Cscope demo project for Low Voltage Motor Control (LVMC) development board and dsPIC33CK256MP508 microcontroller that is available as a PIM (Plug in Module).
The purpose is to demonstrate the X2Cscope firmware based debugger tool features like run-time watch and scope views.
The code functionality is minimalistic in order to avoid unneceseary confusion. The firmware generates a digital sawtooth and a sine signal. There is LED1 that is blinking with the sawtooth signal's period. The LED2 can be controlled manually by the X2Cscope run-time debugger tool. The state of the SW1 can be read out by X2Cscope.
The demo is ready to use with the listed hardwares below.
- Clone or Download zipped project.
- Connect Hardware.
- Open project with MPLAB X
- Build project
- Program the Hardware (HW) with the PICkit on board
- Verify LED1 is blinking
The X2Cscope tool uses the UART to transfer data from and to the HW. To use this feature follow the steps:
- Verify if X2Cscope plug-in is installed within MPLAB X. Detailed user guide: https://x2cscope.github.io/
- Open X2Cscope
-
Verify UART settings at the Connection Setup tab and also check the COM port number on the PC. (device manager)
-
Connect to the HW with clicking on the connect sign:
- Use the Watch and Scope data views (available on the Data Views tab).

Peripherals are configured by MCC according to the LVMC board schematics.
If you need more details of peripheral configuration, just open MPLAB X then MCC with the MCC button:
To use the demo only the MPLAB X IDE and XC16 compiler is required.
- MPLAB X Integrated Development Environment.
- XC16 Compiler: Compiler for the Microchip 16bit MCUs
- XC16 v1.60 - Microchip C compiler for 16bit micros
- MCC v4.0.2 - Configure peripherals and generate low levev drivers
- X2Cscope v0.5 - Run-time firmware based debugger tool
