Keil C51 IDE Simulator Software
C51 Development Tools
Keil development tools for the 8051 microcontroller family support every level of developer from the professional applications engineer to the student just learning about embedded software development. The industry-standard Keil C Compilers, Macro Assemblers, Debuggers, Real-time Kernels, and Single-board Computers support ALL 8051-compatible derivatives and help you get your projects completed on schedule.
The following table shows the Keil C51 Product Line (across the top) and the Components that are included (along the left side). You may use this information to find the development tool kit that best fits your needs.
Software Development Cycle
When you use the Keil µVision, the project development cycle is roughly the same as it is for any other software development project.
- Create a project, select the target chip from the device database, and configure the tool settings.
- Create source files in C or assembly.
- Build your application with the project manager.
- Correct errors in source files.
- Test the linked application.
Tools And Other Resources
µVision IDE
The µVision IDE combines project management, a rich-featured editor with interactive error correction, option setup, make facility, and on-line help. Use µVision to create your source files and organize them into a project that defines your target application. µVision automatically compiles, assembles, and links your embedded application and provides a single focal point for your development efforts.
C51 Compiler & A51 Macro Assembler
Source files are created by the µVision IDE and are passed to the C51 Compiler or A51 Macro Assembler. The compiler and assembler process source files and create relocatable object files.The Keil C51 Compiler is a full ANSI implementation of the C programming language that supports all standard features of the C language. In addition, numerous features for direct support of the 8051 architecture have been added.The Keil A51 macro assembler supports the complete instruction set of the 8051 and all derivatives.
LIB51 Library Manager
The LIB51 library manager allows you to create object library from the object files created by the compiler and assembler. Libraries are specially formatted, ordered program collections of object modules that may be used by the linker at a later time. When the linker processes a library, only those object modules in the library that are necessary to create the program are used.
BL51 Linker/Locator
The BL51 Linker/Locator creates an absolute ELF/DWARF file using the object modules extracted from libraries and those created by the compiler and assembler. An absolute object file or module contains no relocatable code or data. All code and data reside at fixed memory locations. The absolute ELF/DWARF file may be used:
- To program an Flash ROM or other memory devices,
- With the µVision Debugger for simulation and target debugging,
- With an in-circuit emulator for the program testing.
