What are ICC compilers?

ImageCraft C compilers are low cost ANSI C compilers that runs on an IBM-compatible PC. They produce code that will run on the corresponding target microcontrollers. For example, ICCAVR is for the Classic and Mega AVRs from Atmel.

All ImageCraft compiler packages include a full ANSI C compiler, a macro assembler, linker, C-subset library, librarian, and library source. All versions include a Windows Integrated Development Environment (IDE). All versions come with comprehensive HTML help and a PDF manual. Most versions come with an optional 90+ page printed manual.

Although the following description is for ICCAVR, features are generally applicable to all ImageCraft compilers.

ICCAVR Features

• comprehensive target support:
  • ICCAVR supports all AT90S and ATMega devices that have SRAM (not 90S1200) and AT94K FPSLIC. New enhanced core megas such as the ATmega8 through to ATMega2560 are all supported.
  • Strings may be placed in either SRAM or FLASH.
  • Write interrupt handlers in C.
  • Supports inline assembly and can interface with assembly modules.
  • Byte operations.
  • Automatic generation of bit I/O instructions such as sbi, cbi, sbis, ... etc.
• powerful and user-friendly IDE:
  • Fast 32-bit 95/98/NT/2000/XP program, accepts long file names.
  • Uncluttered tabbed editor windows.
  • C editor with syntax highlighting, jump to matching braces, block indents and outdents, extensive bookmark support, and code templates.
  • Project Manager automatically generates standard makefile, one click to rebuild.
  • Simple interface to select compiler options, including choose from a database of popular chip configurations for memory address setup, select different versions of "printf" based on features and code size, and lots more!
  • Built-in ANSI Terminal emulator for target communication.
  • Includes Application Builder to generate peripheral initialization code.
  • Built-in ISP (In System Programming) tool with support for the STK200 dongle and the STK500 board. Can automatically download code after a successful project build.
• ANSI C compiler:
  • Modern fast C Compiler with full support for the ANSI C language. NOT a micro-C or extended K&R C, but a robust ANSI C front end written from the ground up, which has been in use for over 10 years.
  • 32-bit longs, 32-bit IEEE single precision floating point.
• optimizations:
  • Device specific instructions such as sbi, cbi, sbis, ... etc.
  • Optimized switch handling.
  • Algebraic simplifications.
  • Block level common subexpression elimination.
  • Advanced register allocation.
  • Peephole optimization.
• assembler / linker:
  • Relocatable assembler and linker.
  • Assembler directives include conditional processing, include files, macros and textual defines.
  • Multiple named sections, memory address may contain holes for discontiguous memory spaces.
  • Industry standard output formats include Intel HEX, and AVR COFF.
• debugger support:
  • ICCAVR supports Atmel's AVR Studio and other COFF capable debuggers.
  • Support for the new Flash Design ISD (In System Debugger).
  • Compilers produce listing files that are usable by most assembly level debuggers using conversion programs.
• libraries:
  • Subset of ANSI C library including printf, memory allocation, strings, and math functions.
  • Target-specific functions such as those for accessing EEPROM and various subsystems (SPI, ADC, I²C, LCD etc.)
• documentation:
  • Online HTML Help and PDF manual. Printed manual (> 100 pages) supplied or available in most cases.
• third party tool support:
  • Processor Expert's PE and Embedded Beans for device initialization and processor code libraries.
  • Command line compilers callable from other editors (e.g. Ed for Windows, Codewright). Multiedit interface DLL also available.
  • Various debuggers.
• technical support:
  • Excellent technical support via email. Typical turnaround time is the same day!
  • Free 6 months maintenance update via download from the web.
  • Low cost annual maintenance plans (see below).
• availability and pricing:
  • ICCAVR fully functional 45-day demo may be downloaded from the ImageCraft website (click on downloads button).
  • When you purchase the compiler, you will be issued with an unlock disk or dongle (extra cost) to remove the 45-day limit.
  • Standard version owners may upgrade to the Advanced or Professional versions for the difference in price.
• maintenance contracts:
  • Annual (1 year from date of purchase), renewable (E-mail capability required)
  • Entitles the purchaser to:
    • priority technical support
    • automatic E-mail notification of bug fix releases (receivable by FTP)
    • discount on the price of any upgrades during the term of the contract

Advanced Version Features

• The ImageCraft Code Compressor ™ optimiser, which reduces final code by 5-15%. This state-of-the-art whole-program optimiser is not available in any other commercial embedded compilers.
• Support for 128K and 256K bytes megaAVRs.
• Graphical interface to RCS (GNU Revision Control System).
• Code Browser ™. (coming soon)
• Debug under AVR Studio includes structure members info.

Professional Version Features

• Includes Global Optimizer. Improve program size and runtime speed by 10-15%. 

ICCtiny Features

Please note that ICCtiny has been end-of-lifed. We may be able to get stock if requested but support will be minimal...
ICCtiny is only for AVRs without SRAM. If your AVR has SRAM, please use the ICCAVR compiler.

• The world's FIRST ANSI C compiler toolset for the Atmel TinyAVR (tm) devices
• Uses the same user friendly IDE as our best selling ICCAVR product for the AVR devices, including syntax colouring editor, Project manager, and simple setup for target devices.
• Modern fast ANSI C front end
• Written from the ground up to take advantage of the TinyAVR architecture, efficient use of internal resources
• Optimizations include
  • device specific instructions
  • algebraic simplifications
  • block level common subexpression elimination
  • advanced register allocator
  • peephole optimize
  • dead code elimination
  • copy propagation
  • unreachable code elimination
  • loop invariant code motion

ImageCraft Compiler Prices

The following prices are subject to revision without notice due to rapidly changing exchange rates!

In most cases, prices will be the current US$ price adjusted by exchange rate.

Prices in green have been revised assuming AUD1.00 = USD0.73

2 June 2009: The exchange rate is now about AUD1.00 = USD0.80

Please inquire about current pricing

NOTES

• Dongles are keyed to a particular compiler type and are USB models. If you order a dongle with the compiler, the normal software license will not be supplied.
• Please add $13 (+GST) to cover packaging and Express Post within Australia. Please call for packaging and postage costs to other countries.
• The ICCAVR compiler does not support the AT90S1200 and others without SRAM. For these, you should use ICCtiny. ASM is supported on all AVRs. Maximum code output is currently 64K bytes for the standard compiler (affects ATmega103, ATmega128 and larger). The advanced and professional versions can output code for the 128K and 256K megaAVRs and include the Code Compressor optimiser and extra debug features. 
• Upgrades within a version (ie, V7std to V7adv) are priced as the difference between the two prices.
• All prices are in Australian Dollars except where noted. MasterCard and Visa accepted but we have to add 2% to cover bank fees. Direct deposit details available on request. Australian customers should add 10% GST. Export sales are GST free.

For AVR product development, we can supply the Atmel STK500 development board and AVRISP programmer.

Upgrades

Please contact us with the registration number of your product, so we can give you the upgrade discount. You must be able to supply your existing serial number before your upgrade order can be accepted.

Programmer's Editor  The ImageCraft editor is good but if you are looking for something better, we recommend (and use) ED for Windows. It is a great Australian product at a very reasonable price and leaves all the IDE editors I have seen in the dust... ;-).
