Atari Lynx programming tutorial

[rmzalbar]

If that would happen to be the issue, some programs that are good for creating pixel art with indexed colours are for example gimp, aseprite or you could try this: http://atariage.com/forums/topic/273118-tiny-sprite-editor-for-lynx/

 

This is quite cool. Thank you!

I've been using sprpck 1.98, and that worked well enough with BMP files. I just wanted to try making transparent (shaped) sprites, a feature of sp65. I'm still looking for a way to export a PCX with a 4-bit index before that can happen.

 

You can do transparent sprite using sprpck, but perhaps I misunderstand something here...

[rmzalbar]

Got it working with 8-bpp PCX (4-bpp didn't work) by following the syntax in Karri's post. The cc65 documentation and -h text didn't provide a clear syntax. Thank you,

 

Edit: not really working with 8-bpp images, they still need to be 4-bpp. See following post for the real solution.

Well. I had many issues with corrupt sprites or failed conversion for both .PCX and .BMP with all utilities. The issue, in case anyone else follows me, turned out to be the "Remove unused colors from colormap" option in GIMP2 when changing image->mode to indexed. By default it was checked. UNCHECK IT. Now, no further problems with any sprite conversion tools either .pcx or .bmp, and they save as 4-bpp instead of 8 when exported.

Gimp:

Image->Indexed

Choose number of colours 16

Export as pcx

I must, say, I never have any problem with exported bmps from gimp.

I experienced this stuff as well, I had written down some notes to remember the next time I would need it:

• Sprites with for example two colours caused problems when remove.
• Sprites with many colors caused problems when not remove xP
• Not remove seemed to usually work better

Aseprite is so much easier to use if you're more of an 'artist-type', but you have to pay for that. Gimp is awesome since it's got all the tools you could imagine, but it's less intuitive to use.

A week ago I updated the setup of a Windows-based device to use Visual Studio 2019, with new instructions to get it to work, new screenshots and a new HelloWorld version that is compatible with the latest CC65 version. Hope you like it.

Hello Everyone,

I took the liberty of opening a new topic on the tutorial series. The main reason (besides my big ego) is that the notifications on new parts and potential discussion is now scattered throughout the Atari Lynx and Programming forum and multiple topics. Also, it gives a single, easy to find location for the source code that goes with the tutorials.

So, for your convenience, here is the list of tutorial parts:

• Part 1: Getting started
• Part 2: Development environment for Windows
• Part 3: Analyzing Hello World
• Part 4: Creating a project
• Part 5: Exploring TGI
• Part 6: Colors
• Part 7: Basics of sprites
• Part 8: Changing appearances
• Part 9: Advanced sprites
• Part 10: Collisions
• Part 11: Pens and more collisions
• Part 12: Memory mapping
• Part 13: UART
• Part 14: Timers
• Part 15: Memory and segments
• Part 16: Cartridges
• Part 17: Interrupts
• Part 18: Files

Let me know if you find things unclear, wrong, have suggestions for topics, see room for improvement or anything else.
I hope you will find it useful and take up the programming challenge. You can take my word for it, or that of Karri, ninjabba, Matashen, sage, GadgetUK, vince, obschan, TailChao, Sebastian, Wookie, Shawn Jefferson, toyamigo, or any of the other developers: it is a lot of fun.

 

I've added the sources, tools and documentation for the CC65 2.13.9 SVN 5944 which is a known stable build. Remove the .txt extension for the sources archive.

It’s amazing! But what if you code in asm only?

@LX.NET Would your Visual Studio 2019 setup work with Visual Studio Code?

To some extent. I would recommend using DevContainers with VSCode. I will put up my current setup for coding with it and to me it is much better than VS. Only thing that VS can do better is provide IntelliSense for your C code but I find that to be less important.

Well, that's what I usually do for the Lynx. Downside is it's all raw assembly, with very few "standard" libraries. I use one source lib for reading/writing EEPROM saved game data, but otherwise it's all roll-your-own.

Yep!

 

I've decided to do more 7800 stuff as I think it has some more potential but the lynx won't be forgotten. I don't think I'll be getting a lynx this christmas though... =/

Nevermind, I found a solution.

I've been following your tutorial for setting up VS 2019 but I can't compile anything, it spits out a 58 count list of errors all in the CC65 header files which are untouched. Kind of confused, I had cloned your Hello World example project from Github and that compiled fine but creating a new project following the tutorial does not.
