PIC16F15244 Curiosity Nano contains an on-board debugger for
programming and debugging. The on-board debugger is a composite USB device consisting of
several interfaces:
- A debugger that can program and
debug the PIC16F15244 in MPLAB® X IDE
- A mass storage device that allows
drag-and-drop programming of the PIC16F15244
- A virtual serial port (CDC) that
is connected to a Universal Asynchronous Receiver/Transmitter (UART) on the PIC16F15244, and provides an easy way to communicate with the
target application through terminal software
- A Data Gateway Interface (DGI)
for code instrumentation with logic analyzer channels (debug GPIO) to visualize
program flow
The on-board debugger controls a Power and Status LED (marked PS) on the PIC16F15244 Curiosity Nano board. The table below shows how the LED is
controlled in different operation modes.
Table 1. On-Board Debugger LED
Control| Operation Mode |
Power and Status LED |
|---|
| Boot Loader mode |
The LED blinks slowly during power-up |
| Power-up |
The LED is ON |
| Normal operation |
The LED is ON |
| Programming |
Activity indicator: The LED blinks slowly during
programming/debugging |
| Drag-and-drop programming |
- Success:
- The LED blinks slowly for 2 sec
- Failure:
- The LED blinks rapidly for 2 sec
|
| Fault |
The LED blinks rapidly if a power fault is detected |
| Sleep/Off |
The LED is OFF. The on-board debugger is either in a
sleep mode or powered down. This can occur if the board is externally
powered. |
Info: Slow
blinking is approximately 1 Hz, and rapid blinking is approximately 5 Hz.
