An ANSI C Compiler for the RCA 1802 family of processors
A full C compiler for the 1802 based on the LCC retargetable C compiler by Fraser and Hanson
LCC1802 requires the asl cross assembler developed by Alfred Arnold
- The releases contain the windows binaries for the compiler and assembler. the whole directory should be placed at c:/lcc42/
- the bat c:/lcc42/lcc42/file buildvisualstudio.bat will compile lcc1802 from the source
command line examples use pi as the userid - tested on raspbian
- switch to the root directory:
cd /
- make a directory for lcc1802: sudo mkdir lcc1802
- give yourself ownership of it:
sudo chown lcc1802 pi
- clone the repository:
git clone https://github.com/bill2009/lcc1802.git
- switch to the directory:
cd lcc1802
- ls will show you directories examples/ with sample programs, include/ with the header files, bat/ with script and batch files, and lcc42/ with the source code
- switch to the source directory:
cd lcc42
- make the build directory:
mkdir build
- make the project:
make BUILDDIR=build all
- add links to the executables to /usr/bin/:
sudo ln -sf /lcc1802/lcc42/build/lcc /usr/bin/lcc
sudo ln -sf /lcc1802/lcc42/build/rcc /usr/bin/rcc
sudo ln -sf /lcc1802/lcc42/build/copt /usr/bin/copt
- at this point the compiler is installed and can be used to compile C to assembler :
lcc -S tst/8q.c
cat 8q.s
-
you now need the assembler asl: you can download the latest c source from http://john.ccac.rwth-aachen.de:8000/as/download.html For Raspbian it was just a matter of running make and make install
-
at this point the compiler and assembler can be used to prepare hex files for execution:
lcc tst/8q.c
cat 8q.hex
more <8q.lst
- because of the way the assembler parses its parameters, they have to be passed differently in linux. For example, "-Wa-D CODELOC=0x2000" becomes "-Wa-D" "-WaCODELOC=0x2000" However, multiple symbols can still be combined as "-Wa-D" "-WaCODELOC=0x2000,STACKLOC=7fff"
