The Development Toolchain ( IDEs, Compilers & Utility Tools ) for ATmega & ATxmega
The Difference between ATmega and ATxmega from Developer's Point of View
- The Special Function Registers (SFRr / bitnames of the onchip peripherals are all different between ATmega and ATxmega.
- DE.Wikipedia "Processor register", DE.Wikipedia "Register (Computer)" - “Special purpose registers ( SPR )”, “Spezialregister”.
- For each development tool ( e.g. C/C++ compiler ), you need to get proper files ( e.g. C/C++ header files ) that support the ATxmega for the compiler you plan to use.
- For each C/C++ application you develop, you have to use the right C/C++ header files, and use the right SFrs/bitnames of the really-existing onchip peripherals of the real target in your source code files.
- Additionally, the developer must instruct the compiler to generate code exactly for the specific CPU, by setting the appropriate compiler switch. See AVR Libc "Using the GNU tools".
- For example, old AVRs and some AVRtiny don't have a MULtiplication unit. So for these targets,the C compiler has to do shifts+adds to multiply, instead of using the MUL instruction.
In-system Programming ( ISP ) / In Circuit Serial Programming ( ICSP ) & On-chip Debugging ( OSD )
Hardware Tools
- Atmel.
- The in-circuit debugger Atmel JTAGICE 3.
- “Mid-range In-System Debugger for Atmel 8- and 32-bit AVR Microcontrollers”.
- Currently it just works with Atmel AVR Studio 5.
- It doesn't and will never work with Atmel AVR Studio 4.
- The device has an ID number, which is printed on a label glued on the device box. An installed Windows driver is dedicated for a single device ID. I.e. you can control several different devices from one Windows host, by connecting several devices to one host and installing a Windows driver for each device. The little drawback: If you have 2 devices and want to connect the one device instead of the other one to the Windows host, you must reinstall the Windows driver.
- You don´t need the device for uploading and running a software ( this might be done by the USB connection by FLIP if you install an USBF DFU bootloader ), you just need it for debugging with Atmel Studio 5.
- On the other hand, if you debug your software using JTAGICE3, you don´t use FLIP to upload the code, but you overwrite the Flash memory by JTAGICE3 and so an installed bootloader. As an installed bootloader is mandatory for the use of FLIP, serious use of FLIP during the debugging phase of the development of a software is not intended.
- Atmel staff members told me inofficially, that a free ( command line ) untility to work with the tool on Windows is under development.
- The in-circuit debugger Atmel AVR Dragon.
- EN.Wikipedia "Atmel AVR" - “The Dragon also allows debugging of all AVRs via JTAG or DebugWire; a previous limitation to devices with 32 kB or less program memory has been removed in AVRstudio 4.18”.
- Frank Erdrich "µController-Projects" - The OpenSource hardware & software “Projekte / AVR JTAG-Interface” ( last update: 2005-02-12 ).

- OLIMEX Ltd. "AVR-JTAG-L JTAG DONGLE FOR PROGRAMMING AND EMULATION", RS-232 interface - “Note this is not AT-JTAGICE-MK2 and supports only ATmega16, ATmega32, ATMega323, ATmega162, ATmega169, ATmega128 microcontrollers”.
- OLIMEX Ltd. "AVR-USB-JTAG OPTOISOLATED USB JTAG DONGLE FOR PROGRAMMING AND EMULATION" - “AVR-JTAG-USB is completely analog of ATJTAGICE (AVR Studio thinks it works with original ATJTAGICE). Note this is not AT-JTAGICE-MK2 if you want to work with the newer devices or with debug wire this JTAG will not do the job”.

Free IDEs
AVR Studio
- In opposite to the development tools of other chip manufacturers,
- Atmel's development system “AVR Studio” ( the IDE ) is free.
- “AVR Studio” may use the OpenSource compiler SourceForge "WinAVR" as standard compiler, and not a proprietary own tool.. So with this compiler, there is no artifical “code size limit”, neither for 8-bit nor for 32-bit.
- Sample projects are in the AVR Studio 4 folder “C:\Program Files\Atmel\AVR_Tools\AVR Toolchain\doc\avr-libc\examples” #.
- Sample projects are in the AVR Studio 5 folder “C:\Program Files\Atmel\AVR Studio 5.0\AVR Toolchain\doc\avr-libc\examples” #.
- Both “AVR Studio 4” and “AVR Studio 5” install an AVR Jungo USB driver, as interface for embedded devices.

- Quantum LeaPs - See Simulation & Model Based Development - “State Diagrams Tools with commercial and OpenSource License”.
Commercial IDEs with Compilers
- The commercial E-LAB Computers "AVRco" for Windows - “Pascal-scm für Atmel AVR”.
- The free Standard release of AVRco - Code size limited to 4 kBytes Flash.
- The free Mega8/Meg88 release of AVRco - Code size limited to 8 kBytes Flash AND Mega8/88.
- In general, there is support for all ATTiny, ATmega and now for all ATxmega, too. The CPU description is based on ”.DSC” files, not on ”.H” files. The compiler loads the requested file after the instruction “Device = XMegaxxx”. At this moment the compiler knows all relevant facts of the CPU. For example, if you try to load an USB driver in your software, though the targeted ATxmega has no USB onboard, a compiler error is generated. So if you should have a brand-new CPU once, look for if there is already a proper ”.DSC” file in the directory “C:\Program Files\AVRco\AVRco”.
- The compiler is bundled with hardware, which works as a dongle: An included InCircuit Programmer + JTAG Debugger ISP3.
- The debugger doesn't and won`t support debugWIRE. It supports:
- ATmega CPUs with JTAG and up to 128K Flash.
- ATxmega CPUs.
- The next generation of InCircuit Programmers + JTAG Debuggers of this company will support the use of the PDI interface for debugging, with ATxmega CPUs.
- The commercial IAR Embedded Workbench for Atmel AVR for Windows - “Integrated development environment and optimizing C/C++ compiler for AVR”.
- The free “KickStart edition of IAR Embedded Workbench”.
- It has a 4 KBytes code size limitation.
- It does (normally) not include source code for runtime libraries.
- It does not include support for MISRA C.
- An AVR assembler is included. There is the rumour, that the size limit of the Kickstart edition is a size limit of the C compiler, not of the assembler ?!
- By the C-Spy tool, hardware debugging is supported with many AVR hardware debuggers, including JTAGICE3.
- The commercial HP Infotech "CodeVisionAVR Compiler" for Windows - “C Compiler” ( not C/C++ ! ).
- The compiler supports inline assembly code and calling functions written in assembly.
- You can access the C global volatile variables from assembler.
- If you want to use a whole module written in assembly, you must create a .C file that contains all the assembly code enclosed between: #asm .. #endasm.
- CodeVisionAVR V2.05.3a ( and newer ) fully supports the ATxmega chips.
- CVAVR creates a .COF object file that can be opened in AVR Studio and source level debugged using JTAGICE or AVRONE.
- A built-in CodeWizardAVR Automatic Program Generator allows you to write in a matter of minutes all the code needed for implementing many frequently needed functions.
- The Shareware Karisu & ImageCraft Creations Inc "ICCV8 for AVR" for Windows - “C Compiler Tools with Windows IDE for Atmel AVR Microcontrollers” ( not C/C++ ! ).

-
- BASCOM-AVR Help "ATXMEGA" - “The power of the AVR is/was the the linear memory architecture. In the Xmega this has been changed : the registers are placed into a separate address space”.
- The BASCOM-AVR demo version is limited to 4KB of code. As the demo version is older than the current commercial version, it does not support ATxmega ( as of 2011-09-16 ).
- Each CPU supported by BASCOM has its own ”.DAT” file ( e.g. ATmega88 = m88def.dat, ATmega88P = m88pdef.dat ). In the full version of Bascom AVR there is the file history.txt with a short description of the changes made to the compiler and new supported chips are always listed.
- Even if there is such a definition file, some CPU functions / modules might not be supported by BASCOM ( e.g. the CAN function / module is not supported by BASCOM ). But you can always use the registers yourself direct to use these kind of functions.
- As at this moment ( 2011-09-16 ) there is no explicite “ATxmega256A3BU” support, have a try with “ATxmega256A3B” = xm192D3def.dat for use with the “Atmel AVR XMEGA-A3BU Xplained kit”.

Auf der PC-Seite nutzt man entweder den virtuellen COM-Port (VCP, ProductID PID EA60 ist voreingestellt) oder den direkten USB-Treiber USBxpress (ProductID PID EA61, kann mit einem Tool von Silab eingestellt werden, welches im Development-Kit von Silab enthalten ist, siehe unten Medien/Links). Das Mikrocontroller-Modul lässt sich zum Beispiel sehr gut für eine Übertragungsrate von 250.000bps konfigurieren (USBxpress Treiber genutzt)”.
- The Setup information files “lowcdc.inf” and “avr.inf” are shipped with Osamu Tamura @ Recursion Co., Ltd. "AVR-CDC". The installation of one of these files enables Windows to load Windows's pre-installed driver “usbser.sys”, which performs virtual COM ports over the CDC protocol.
