Curiosity Nano
Curiosity Nano is an evaluation platform of small boards with access to most of the microcontrollers I/Os. The
platform consists of a series of low pin count microcontroller (MCU) boards with on-board debuggers, which are
integrated with Atmel Studio/Microchip MPLAB
Window is displayed with links to key documentation, including relevant user guides, application notes, data sheets,
and example code. Everything is easy to find. The on-board debugger features a virtual serial port (CDC) for serial
communication to a host PC and a Data Gateway Interface (DGI) with debug GPIO pin(s).

On-Board Debugger Overview
ATtiny3217 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 ATtiny3217 in Atmel Studio/Microchip MPLAB
•
A mass storage device that allows drag-and-drop programming of the ATtiny3217
•
A virtual serial port (CDC) that is connected to a Universal Asynchronous Receiver/Transmitter (UART) on the
ATtiny3217, 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 ATtiny3217 Curiosity Nano Board. The
table below shows how the LED is controlled in different operation modes.

Debugger
The on-board debugger on the ATtiny3217 Curiosity Nano Board appears as a Human Interface Device (HID) on the
host computer's USB subsystem. The debugger supports full-featured programming and debugging of the
ATtiny3217 using Atmel Studio/Microchip MPLAB

Success:
The LED blinks slowly for 2 sec.
Failure:
The LED blinks rapidly for 2 sec.
The LED blinks rapidly if a power fault is detected.
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.
