ATtiny817 Xplained Pro Getting Started Xplained Pro Quick Start Steps to start exploring the Xplained Pro platform: Download and install Atmel Studio. Launch Atmel Studio. Connect the Debug USB port on the evaluation kit to the computer using a USB cable (Standard-A to Micro-B or Micro-AB).
DGI. The EDBG controls two LEDs on the ATtiny817 Xplained Pro, a power LED and a status LED. The following table provides details on how the LEDs are controlled in different operation modes.
ATtiny817 Xplained Pro For additional information on the EDBG, see the EDBG User Guide. Xplained Pro Analog Module (XAM) 3.2.1 Overview The Xplained Pro Analog Module (XAM) extends the embedded debugger with high dynamic range current measurement. This enables power profiling of the target system.
ATtiny817 Xplained Pro • C: This is used to control and configure the XAM. • SPI: Current measurement data is streamed to the EDBG via this interface. This is a unidirectional channel from the XAM to the EDBG. • SWD: The MCU in the XAM is programmed via SWD from the EDBG.
3600 Maximum current [mA] uint16_t Power Sources The ATtiny817 Xplained Pro kit can be powered by several power sources, as listed in the table below. Table 3-4.

Hardware User Guide Power Distribution ATtiny817 Xplained Pro has two power sources; EDBG USB and external 5.0V. The kit will automatically select the source to draw power from. The kit has two on-board 3.3V voltage regulators, one for the EDBG and XAM, and one for the ATtiny817 and other peripherals.
Xplained Pro Standard Extension Headers The ATtiny817 Xplained Pro headers EXT1 and EXT3 offer access to the I/O of the microcontroller in order to expand the board, e.g. by connecting extensions to the board. These headers are based on the standard extension header specified in the table below.

Note: Signal functions in italic use alternative pin location. These have to be configured in the PORTMUX register of the device. 4.2.2 UPDI Debug Connector ATtiny817 Xplained Pro has a 10-pin 50-mil UPDI Debug Connector that can be used to attach external debuggers to the ATtiny817. Table 4-3. UPDI Debug Connector UPDI Debug...
4.3.2 Crystal The ATtiny817 Xplained Pro kit contains a 32.768 kHz crystal, which can be used as clock source for the ATtiny817 device. The crystal has a cut-strap next to it, which can be used to measure the oscillator safety factor. This is done by cutting the strap and adding a resistor across the strap. More information...
ATtiny817 Xplained Pro 4.3.3 There is one yellow LED available on the ATtiny817 Xplained Pro board that can be turned ON and OFF. The LED can be activated by connecting the I/O line to GND. Table 4-6. LED Connection ATtiny817 Pin...
4.4.4 XAM Configuration On the ATtiny817 Xplained Pro, the MCU and the MCU peripherals (e.g. extensions) are powered by their own regulator, as shown in the figure below. All the other parts of the board, mainly the embedded debugger and the accompanying Xplained Pro Analog Module (XAM), are powered from a separate regulator.
