Small Device C Compiler
During Memofest
2015, Andy Key
demonstrated his library of assembler routines to control the
MTX VDP and sound chip, the routines are callable from C which
should make writing programs for the MTX a little easier, with
only the speed critical parts of the code using assembly
language. Andy had designed the libraries for integration
with SDCC - the
Small Device C Complier.
SDCC is released under a GPL license and is currently hosted
on SourceForge, where it is described as "a retargettable,
optimizing ANSI - C compiler suite that targets [various]
microprocessors [, including the ] Zilog Z80."
The purpose of this page to to share SDCC resources that may
be useful for developers using "C" for the MTX series

Small Device C Complier |

Although C is a relatively low level language, it does
not, in itself, interface directly with the target
hardware. In order to target particular hardware, such
as the MTX computer, hardware specific functions must be
coded at the machine language/assembler level that the
programmer can call from within C.
Back in the
day, C compilers such as Small C, Aztec C, etc. were
supported by their own suites of C functions. Text
editors were used to create the C source code and the C
compiler and linker used to generate an executable
object file - the program.
Most programmers today
use fancy Windows based Integrated Development
Environments (IDE) to provide a user friendly front end
to the complier.
To make SDCC more useable for
MTX users means that someone first needs to do the
ground work to build a library of MTX function calls
and, ideally, identify other programming support tools.
