15 IDE Overview Continued C51 - Optimising Ansi-C compiler for the 8051 family The unsurpassed Industry Standard C Compiler Generates optimised specific code Flexible variable allocation with bit, data, bdata, idata, xdata and pdata Supports data types including bit, (signed/unsigned) char, int & long Comprehensive mathematical libraries Supports both memory specific and generic pointers Supports parameter passing including BIT variables Supports re-entrant functions (same function can be called from both the main and interrupt service routine) Interrupt and re-entrant functions can be directly coded in C51 Direct support for SFR's and single BIT variables by name Comprehensive symbol and debug information available for use by dscope, EPROM Emulators etc. A51 Macro Assembler The A51 assembler is a macro assembler for the 8051 microcontroller family. It translates symbolic assembly language mnemonics into relocatable object code where the utmost speed, small code size, and hardware control are critical. The macro facility speeds development and conserves maintenance time since common sequences need only be developed once. The A51 assembler supports symbolic access to all features of the 8051 architecture and is configurable for the numerous 8051 derivatives. BL51 Linker/Locator Combines one or more modules into one executable 8051 program Overlaying of local data variables greatly reduces the overall RAM requirements of many user programs Supports up to 64k of XDATA for storing external variables in RAM Code limit depends on package purchased 10

16 IDE Overview Continued Project Based Development Back in the old days of DOS development tools, it was necessary to run separate command line driven programs to compile, link and then produce a hex file. This was not only time consuming, but could also lead to a lot of compilation and linking errors due to typing errors. The Keil µvision Integrated Development Environment (IDE) takes care of all file management for you, so all you have to worry about is actually writing code that works! The table below show the different file contained within a typical Keil C51 project. Files contained within a typical µvision project Extension Example Description.prj example.prj Project File: Contains names of all source files associated with the project and includes information for compiling, assembling & linking to generate an executable target program..c cfile1.c C Source File: This file is an ASCII text file containg a program written in C51. It is possible to cfilen.c have as many source files as are required. Eg. 1 to n.a51 a51file1.a51 Assembler Source File: This file is an ASCII text file containg a program wriiten in A51. It is a51filen.a51 possible to have as many source files as are required. Eg. 1 to n.h Reg51.h Include (header) File: This type of file can be used to declare microcontroller-specific register Evalu8r.h information or as a convenient way of including variable declarations..obj cfile1.obj Object File: When a C or assembler source file is compiled, the compiler translates the source into cfilen.obj an object file. a51file1.obj a51filen.obj.lst example.prj List File: A LIST file is created by the compiler when the project or a module within the project is compiled. The file is an ASCII log file of the compilation process and details any errors found. - example OMF51 - Absolute Object File: This file has no file extension. This file conains the actual executable code after a project build. It also contains any symbolic information if the debug options are enable within µvision..m51 example.m51 Map File: A MAP file is created by the compiler when the project or a module within the project is compiled..hex example.hex Intel Hex File: This is a standard output format which can be downloaded to many emulators or device programmers. The actual executable 8051 code is contained in an encoded format within this file..ini example.ini D-Scope Initialisation File: This file contains a script which dscope executes when launching a project.
