LCC1802

An ANSI C Compiler for the RCA 1802 family of processors

Description

A full C compiler for the 1802 based on the LCC retargetable C compiler by Fraser and Hanson

Getting Started

Dependencies

LCC1802 requires the asl cross assembler developed by Alfred Arnold

Installing for windows

  • 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

Installing for linux

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"
