New versions of libcv and libcvu come with music demos and fixed point

[PkK]

libcv 0.18 and libcvu 0.11 have been released today.

 

A highlight of this release are two music demos, one showing how to play a tune on the ColecoVision in just a dozen lines of C code, the other showing more advanced features. The music tutorial tells more about them.

 

Another one is support for fixed point numbers, including some trigonometric functions. These can be very useful e.g. for implementing smoother movement

 

The libraries can be found at http://colecovision.eu/ColecoVision/development/libcv.shtml

 

Here's the list of changes since the previous releases:

 

libcv: Cleaned up Makefile, changed to new style assembler invocation.

libcvu: Cleaned up Makefile, changed to new style assembler invocation.

libcvu: Added support for 10.6 fixed point type cvu_f, including multiplication, division, sine and cosine.

demos: Added two music demos.

libcvu: Changed wording from "NMI handler" to "vint handler" in cvu_sound.h.

libcvu: Restricted pointer arguments in compression initialization functions.
