SDCC 8051 Development System

SDCC is a freeware , optimizing, C compiler that is created by Sandeep Dutta under the GNU General Public License.

 SDCC 8051 Development System - MicroIDE SDCC 8051 Development System

The package includes an ANSI 8051 C Compiler, 8051 Assembler, Linker and example projects, some of which has been added by BiPOM Electronics. The linker that comes with SDCC has been modified by BiPOM Electronics to run SDCC seamlessly in our Micro-IDE environment.

SDCC has applies standard optimizations such as global sub-expression elimination, loop optimizations, constant folding & propagation, copy propagation, dead code elimination and jump tables for 'switch' statements.

The following data types are supported:

short (8 bits, 1 byte)
char (8 bits, 1 byte)
int (16 bits, 2 bytes )
long (32 bit, 4 bytes)
float (4 byte IEEE)

Inline 8051 assembler code can be inserted in C programs. We have packaged the Windows version of the compiler such that:

  • It has a simplified installation
  • It integrates seamless into Micro-IDE, a Windows-based Integrated Development Environment
  • The linker is modified to build under Windows and execute under Micro-IDE
  • Some example Micro-IDE projects have been added to demonstrate serial port, LCD display and I/O access using SDCC and Micro-IDE
