Support for AHCC

[simonsunnyboy]

Starting with today Paradize officially supports C coders on the Atari ST. Simon Sunnyboy plans to move to C in the upcoming time. In this process a lot of libraries and helpful C code will emerge.

You will find those libs and stuffs on the AHCC Support page. AHCC is a free and Pure C compatible compiler that is still developed and supported so go grab the AHCC Compiler package and enjoy!

For the start we have a small library for accessing the IKBD, e.q. reading keyboard, mouse and joystick without the help of TOS. Support libs for switching to ST-LOW, Falcon TrueColor, Jagpad access, DMA Sound and replaying SNDH music will soon follow (hopefully before Outline 2010)

Check our website at http://paradize.atari.org/!

Happy C coding!

Belated thanks from me! This is great news - I had AHCC working (on Hatari anyway, STE isn't set up for colour yet ) so look forward to messing with the Paradize libs soon.

A new addition by me, my ST-LOW setup and access code has been added.

You can enable ST-LOW or ST-MEDIUM on ST,STE,TT and Falcon with this new library for AHCC. It can clear the screen and load basic picture formats such as .PI1 .PC1 and .NEO into memory and display them.

A future version will include basic routines to blit blocks with widths of multiples of 16 to the screen.

Good work.

RG Done a fair bit of work in pure C which as it's compatible may be very useful?

Probably yes but a) I don't like the GODLIB API and B) want to learn how to do it myself.

It is an offer, noone has to forceful use my libs/implementation.

I just added my rasterbar code for AHCC and Pure C to the library. One can now use rasters similar to the rasterbar generator and with few efforts, you can use the data created with that utility with your C codes now.

I ported GT Turbo's interface for Wizzcat Protracker Replay from GFABASIC to C. You can now replay Amiga protracker modules at 12KHz on the STE DMA sound hardware from AHCC. Credits go to GT Turbo and Wizzcat ofcourse!

There is now an RC_COPY equivalent for AHCC, done by me. It has the same functionality as the mentioned GFABASIC command.
It also shares the same limitations like using LINEA and being slow.

*Moderator note* Splitted the evolving discussion as it was offtopic, you can find it in the Coding > C section of the forum.

Another helper routine released.

This time a tile drawing routing for game backgrounds. This routine copies tiles onto screen. The routines are optimized for ST-LOW and tiles can only be blitted in 16pixel columns, at 0,16,32, etc coordinates.

Supported are tile widths of 16, 32, 48 and 64 pixels with any amount of scanlines. Blits are always for 4 planes but the code can be rewritten to draw less planes if desired. (M68K knowledge required.)

Hello all,

I have finished my STE Playfield and splitscreen access routines and hereby open it up for public usage.

This routine is for STE and F030 only. It allows the user to configure a splitscreen display. Each display part has its own 16 color palette and can be scrolled with the STE hardware scrolling parameters.

The scanline at which the split will occur is freely configurable.

The Source code is included in the package. Simply link the assembly library file and use the supplied C header from AHCC and Pure C.

Special thanks to Klapauzius and Nicolas Pomarede for helping with the Timer B stabilizer routine!

Get it from the Paradize website, http://paradize.atari.org/ and the AHCC section.

It should be usable from AHCC and Pure C, and ofcourse from plain M68K aswell. With some rewrites it should be possible to include it from GFA aswell.

Regards,
Simon Sunnyboy / Paradize
