PIC18F47K42 Curiosity Nano features an on-board debugger that can be used to program and debug the PIC18F47K42 using ICSP. The on-board debugger also includes a Virtual COM port (CDC) interface over UART and DGI GPIO. Microchip MPLAB® X IDE can be used as a front-end for the on-board debugger for programming and debugging. Data Visualizer can be used as a front-end for the CDC and DGI GPIO.
