CrossWorks for ARM is a complete C development system for ARM 7 microprocessors. It comprises of the ARM GCC C compiler, the CrossWorks C Library and the CrossStudio integrated development environment.

In order to use CrossWorks for ARM you will need:

- Windows 98, Windows Me, Windows NT 4.0, Windows 2000 or Windows XP.
- A Macgraigor Wiggler for ARM (WNPJ-ARM-20/WNPJ-ARM-14) or compatible parallel port to JTAG interface.
- An ARM 7 target board with 20 or 14 pin JTAG connector. CrossWorks for ARM provides support for several ARM based microcontrollers out of the box in the form of examples and target configurations. CrossWorks can also be easily modified to support other ARM 7 targets, see ARM Target Support for more information.
