Libraries

The c64lib project consists of multiple libraries. Each library is hosted as separate GitHub repository and have corresponding Travis-CI entry defined (see: https://travis-ci.org/c64lib).

There are following core libraries:

• common - the one that hosts some commonly used functions, macros and subroutines; no other c64lib library can work without it. This code is intended to be platform (C64) independent, it complies to typical MOS 6502 assembler syntax (except it is written in KickAss, which is C64 specific at the moment).
• chipset - the one that hosts code that is platform specific and is dedicated to handle typical C64 chipset such as VIC-II, SID, CIA as well as typical C64 memory layout.

There are following auxiliary libraries:

• text - the one that handles displaying text in text mode of Commodore 64 / VIC-II.

There are following application libraries:

• copper64 - utility library that makes raster interrupt programming on VIC-II pleasant and easy.

Library dependencies

The following diagram describes dependencies between internal libraries of c64lib project. There is also an excellent 64spec testing library used and shown as external reference.
