Small Device C Compiler
Encyclopedia
The Small Device C Compiler (SDCC) is an open source
, partially retargetable
C
compiler
for microcontroller
s. It is distributed under the GNU General Public License
. The package also contains a linker, assembler
, simulator and debugger
. As of March 2007, SDCC is the only open source C compiler for Intel 8051
-compatible microcontrollers.
In 2011 the compiler is downloaded on average more than 200 times per day.
The SDCC compiler
was used by the FreeRTOS
project to port its real-time operating system to the 8051-based Silabs
(formerly Cygnal) series of microcontrollers.
