IAR Embedded Workbench for 8051 is a powerful integrated development environment and debugging software for microcontrollers 8051 with the help of language C, C + + and assembler. It provides extensive support for 8051 devices and generates very compact and efficient code. It includes a C compiler and C + +, assembler, linker and debugger, with the possible interaction with external programs. Built-in editor specially configured C syntax, and additional tools and a good built-in help system further facilitates writing programs.
