C

In order to generate our own QR codes natively on the Steckschwein, we drew a lot of inspiration from this article https://8bitworkshop.com/docs/posts/2022/8bit-qr-code.html

It even points to an adapted version of the qrtiny library, that has been made to compile with cc65, including a demo for the Apple ][, using cc65’s own Tiny Graphics Interface (TGI). Which is very nice, because all the hard work has already been done.

We have not implemented TGI (yet?), but we do have our rudimentary BGI (Borland Graphics Interface), which is similar. So all that’s left to do is porting the code to BGI, which has proved to be fairly trivial:

To share my fascination for the numerous sorting algorithm videos on youtube, I took some sorting algorithm examples in C from https://www.geeksforgeeks.org/sorting and visualized them using our BGI compatible C graphics library (more about that later).

The algorithms shown are:

• Bubble Sort
• Cocktail shaker Sort
• Gnome Sort
• Insertion Sort
• Comb Sort
• Heap Sort
• Shell Sort
• Selection Sort
• Quick Sort
• Merge Sort
• Radix Sort

The code examples from https://www.geeksforgeeks.org/sorting are only slightly adapted and could be compiled with cc65 almost instantly. The trick was only to find the places in the code where the interesting search array accesses happen.
