  • Site Cleanup [ 6:22 PM GMT ]

    This probably affects no one, but I have removed the links to the user accounts and site statistics. The user accounts are basically broken, and my web host will be killing the site stats soon for some reason I can't remember, but seemed important when I read the email.

  • Nibbles 68k [ 12:17 AM GMT ]

    After updating the third review lesson and realizing how stupidly Nibbles was written, I went and fixed it.

    It now uses custom interrupts for better timing. There are lots of efficiency updates and style changes to the code. It's a much better codebase now. I'm not going to rewrite the third lesson again, but I just wanted to make a note of the update.

  • Assembly Lessons [ 1:24 PM GMT ]

    I have finished updating the third assembly lesson. This marks the completion of my updates. Everything on Techno-Plaza should now be up to date and compliant with the current version of TIGCC (0.96 beta 8) and TiEmu 3 Beta (Oct 30, 06). Please let me know if you find anything wrong.

    I have updated the second assembly lesson. I noticed a problem in the rowread example that was caused by a change in newer versions of TIGCC. Sorry if you tried to get this to work and it didn't. The new example works.

  • Assembly Lessons [ 4:38 PM GMT ]

    I have updated the first assembly programming lesson. I think this new approach will be better.
    --John David Ratliff
  • C Programming Lessons [ 4:30 AM GMT ]

    Okay, a few quick adjustments and a stupid hack to fix the delay function and Nibbles 68k is working again. It really needs a rewrite, but I'm much too lazy to do that right now. The third review has been updated, which completes the updates of all the TIGCC programming lessons. They are now all relevant again, yay!

    I may try to update the TIGCC assembly lessons too. I have some better ideas on the integration of assembly and C that should make assembly programming easier. We'll see.

  • C Programming Lessons [ 2:16 AM GMT ]

    I have finished updating the tenth lesson. This is a very good thing as there were major bugs in the first example program. There is only one more lesson to fix here. Unfortunately, Nibbles 68k does not work as written with the new TIGCC versions. I will figure out how to fix the program before I can update the third review.

  • C Programming Lessons [ 5:52 PM GMT ]

    Lesson 9 has been updated.
    --John David Ratliff
  • C Programming Lessons [ 3:32 PM GMT ]

    Lesson 8 has been updated. There are some important updates here. First, the bitmanip program now works with the latest TIGCC version, which had optimized the delay() function out of the program, so I replaced it. Second, the lesson also talks about AUTO_INT_5, which is anoter important redirect for keyboard reading in HW2 calcs that I didn't know at the time.
    --John David Ratliff
  • C Programming Lessons [ 2:01 AM GMT ]

    I have updated the 7th lesson.

    I have noticed over the course of my updates many minor typos and mistakes in my lessons. I apologize for this and am correcting everything I find.

    I noticed the recent release of TIGCC 0.96 beta 8 which comes with full support for TiEmu, the replacement for VTI. I am in the process of updating Techno-Plaza so that these new tools can be used. I have noticed that many of my lessons and programs no longer work with the newer calculators or AMS versions. Sorry for that. I hope to have things updated very soon.
