The complete toolchain: µC/51

Develop high quality software for any 8051 in ANSI C. µC/51 comes with an incredible optimizing compiler, you can even write software in ANSI C on 8051's with 1kB of code memory! µC/51 is absolutely complete: user friendly multi file Editor, Compiler, Assembler, Downloader, Source
Level Debugger. You will not need anything else.

With 100% sourcecode TCP/IP-Stack

• Embed the Internet in your applications, since V1.20 acomplete TCP/IP-Stack is included as 100% Source.
• Ultra-Small Footprint: A webserver will run with as littleas 1 kB of RAM and only about 6-8 kB additional code.

Target support

• All 8051's are supported, no specific assumptions.
• Different memory models exactly meet your demands.
• Full 32-bit IEEE Floating Point support.
• Write Interrupt handlers in C.
• Access up to 16 MB code and address space.
• Place global objects in any space: direct internal RAM, indirect internal RAM, external RAM, code, bit.
  

ANSI C compiler

• Full support for the ANSI C language. NOT a reduced subset of C or extended K&R C.
• Especially designed for ext. Harvard Architectures.
• Include assembly language in your C programs.
• compiler writes 100% assembler sourcecode .
• Integral support for source level Debugging.
  

Optimizations (only the most important)

• Call graphs for minimum RAM usage.
• Data flow optimization.
• Device specific instructions.
• Copy propagation.
• Loop reversion.
• Loop rotation.
• Loop induction.
• Strength reduction.
• Common subexpression elimination.
• Smart integral promotion.
• Peephole optimization.
  

Assembler

• Fast Macro Assembler with rich directives.
• Access assembler functions from C.
  

Linker

• Strip linker compresses the code to the minimum.
• Output formats: binary and Intel Hex (more soon...).

Downloader / source level debugger

• Complete OS for downloading programs on development boards (RAM) included as source code.
• Write programs to a Flash memory.
• C level Single Stepping.
• Terminal program included.
  

Libraries

• Subset of ANSI C Library (including strings and printf()).
• I2C Bus Librarie with complete sourcecode.
• Open printf()-formatter (i.e. write your own lcd_printf()).
  

Included demos

• Many demo sourcecodes included, up to a FFT.
• Demos for generic 8051's, Infineon's C515, Texas Instrument's MSC1210, Analog Devices ADµC8xx, etc....
