  • On-Chip Debugging: Run, Single step, Breakpoints, etc. Allows the user to view the internal state of the device.
  • High speed Debugging
  • Programming Interface to flash, eeprom, fuses and lockbits (not debugWIRE)
  • Low speed programming through ISP, or high speed programming through JTAG

Connecting to PC

Before connecting up the JTAGICE XPII for the first time, be sure to install the USB driver on the host computer. This is done automatically when installing the front-end software (Probably AVR Studio). The JTAGICE XPII can connect to the host PC through a USB cable or serial cable (to COM port on the PC).

  • Each JTAGICE XPII has a unique ID, a PC could connects to several Devices at the same time
  • USB Interface: use the PDIUSBD12, USB 1.1
  • RS-232 Interface: use the 9-pin RS-232 cable. Make sure that no other software has control of the COM port where the JTAGICE XPII is connected.
  • The rear panel of the JTAGICE XPII houses the DC jack, power switch, USB and RS-232 connectors.

Connecting to target board

Debugging Interface: JTAG, PDI, debugWIRE (SPI), depending on which interface the target communicates with.
Programming Interface: JTAG, PDI, ISP (SPI), depending on which interface the target communicates with.
The cable has to be changed according to the existed header on the target board. See details displayed below.

  • Connecting to a JTAG target
    • Standard JTAG header, Using the default 10-pin JTAG cable directly
    • Custom JTAG header, Using 10-wire multi color custom connector cable
  • Connecting to a PDI target
    • Using 10-wire multi color custom connector cable
  • Connecting to a debugWIRE or ISP target
    • Standard 10-pin SPI header, Using 10-pin (JTAG) to 10-pin (SPI) probe adapter cable
    • Standard 6-pin SPI header, Using 10-pin (JTAG) to 6-pin (SPI) probe adapter cable
    • Custom SPI header, Using 10-wire multi color custom connector cable

Images 1, 2, 3 and 4 show the header pinouts of the various interfaces:

Powering the JTAGICE XPII

  • Operates using an external power supply providing 9-15V DC
  • Can be powered directly from the USB bus
  • The target board can be powered from another power supply

The AVR Microcontroller and Embedded Systems Using Assembly and C: Using Arduino Uno and Atmel StudioThe AVR Microcontroller and Embedded Systems Using Assembly and C: Using Arduino Uno and Atmel Studio

The AVR microcontroller from Atmel (now Microchip) is one of the most widely used 8-bit microcontrollers. Arduino Uno is based on AVR microcontroller. It is inexpensive and widely available around the world. This book combines the two. In this book, the authors use a step-by-step and systematic approach to show the programming of the AVR chip. Examples in both Assembly language and C show how to program many of the AVR features, such as timers, serial communication, ADC, SPI, I2C, and PWM.

The text is organized into two parts:

  • The first 6 chapters use Assembly language programming to examine the internal architecture of the AVR.
  • Chapters 7-18 uses both Assembly and C to show the AVR peripherals and I/O interfacing to real-world devices such as LCD, motor, and sensor.

The first edition of this book published by Pearson used ATmega32. It is still available for purchase from Amazon. This new edition is based on Atmega328 and the Arduino Uno board.
