Turbo Pascal for 8051 microcontrollers

Pascal is easy to write and easy to read

Turbo51 is a free Pascal compiler for the 8051 family of microcontrollers. If you are programming for the 8051 family of microcontrollers and you like Pascal programming language then you will love Turbo51.

Main features:

Win32 console application
Fast single-pass optimizing compiler
Borland Turbo Pascal 7 syntax
Full floating point support
Mixed Pascal and assembler code
Full use of register banks
Advanced multi-pass optimizer
Smart linker
Generates compact high quality code
Output formats: BIN, HEX, OMF
Assembler source code generation
Source-level debugging with absolute
OMF-51 extended object file

Used optimizations:

Constant folding
Integer arithmetic optimizations
Dead code elimination
Branch elimination
Code-block reordering
Loop-invariant code motion
Loop inversion
Induction variable elimination
Instruction selection
Instruction combining
Register allocation
Common subexpression elimination
Peephole optimization

Turbo51 is released as a freeware. You can use Turbo51 for hobby projects and for serious work. Check documentation pages and code examples that show the syntax, features and generated files. This should be enough to start a 8051 project development with Turbo51. And if you are still missing something or have a problem you can always ask for help.

If you are already familiar with 8051 assembly language programming you can start with Turbo51 as 8051 assembly language compiler and then add some Pascal statements until you become familiar with Turbo51 and Pascal syntax. A good approach is also to compile some Pascal code and then check generated code (ASM file). This way you can learn assembly language, get some ideas on how to write effective code and become familiar with the compiler. Turbo51, like many popular C compilers for 8051, generates optimized code and supports source-level debugging with OMF object file.
