PIC16F15244 Curiosity Nano features an on-board debugger that can be used to program and debug the PIC16F15244 using ICSP. The on-board debugger also includes a virtual serial port (CDC) interface over UART and debug GPIO. MPLAB® X IDE can be used as a front-end for the on-board debugger for programming and debugging. MPLAB Data Visualizer can be used as a front-end for the CDC and debug GPIO.
