It’s too late for today, so the program is untested. I’ll probably test it on my calc the other day when I got more time to waste.
In short, this calculator is extremely limited. Hats off to the contributors at https://algos-casiofx92.com/; you guys are genius.
Note: Access X&Y registers with “Aller a x:y”
The program space is rather limited. Instead of doing I/O the way I’m doing it (by using two registers as the “streams”), you can modify the program to redirect the I/O functions to “Demander valeur” and “Afficher result”. In that case the maximum BF program length is 16*5=80 steps.
Meh… a detailed description of this little project will be covered in a future article (If I actually would do). Basically, I’m trying to make a portable music player / midi synth based around YM2608. I expect this project to take forever to complete…orz
LED numeric display is the icon of HP classics. With just a single 5-bit register inserted, how could they design such a full-featured, flicker-free and properly PWM’d display that has 15 digits?
Sorry for such a long quiescence. Originally I was planning to actually make a board that drives the LED display before writing anything. Unfortunately, since quarter a year ago, I’m completely occupied by all sorts of things, and the plan is delayed forever. I’ll try if I’m free at some point in the future.
This is the first article written in the new “Gutenberg” WordPress editor. Noice!
