A collection of small C (llvm-mos) experiments for the F256K from Foenix Retro Systems. Compiled into .PGZ format for easy executing on the target hardware (or in the FoenixIDE emulator).

Foenix Retro Systems is a homebrew effort to bring 8/16/32-bit era processors in a new, reimagined retro series of computer designed by Stefany Allaire (https://twitter.com/StefanyAllaire)
Simply writes a word with random foreground and background text color
This will display fetch the clock data using the kernel call Clock.GetTime, which depends on the RTC (real time clock, needs a battery) and properly formats the output into human-readable text, using the library's textPrintInt functions. In order to accomplish this, a small helper function converts the data obtained in BCD (binary coded decimal - https://en.wikipedia.org/wiki/Binary-coded_decimal). Last but not least, the text of the clock's converted data is refreshed every second on screen.
This will set up 6 kernel timers, some based on frames, some based on seconds, in order to drive a character based animation (which cycles between characters #2 to #14, which look like partially filled rectangles). The full list of timers used is:
- every frame
- every 5 frames
- every 20 frames
- every second
- every 3 seconds
- every minute
This is meant for the F256K2 (and Jr. "the Second") since it targets the SAM2695 Dream IC found on those machines only. Use the arrow keys left/right to select the note to be played, use the up/down to select the instrument (from 0 to 128) and play a short test note with the space bar. If you plug in a MIDI controller in the MIDI in port, you can also play that way (much easier and faster for tests). The relevant MIDI uart register addresses will try to display in real time the data that passes through them.
This is my game entry to the Foenix community's Game Jam for Oct 25-27 in 2024. It's a musical game where you can freely play notes using the keys on your keyboard (white row of keys from Z to / and Q to ], black keys from A to ; and 2 to +). By default, it can use the MIDI chip in the K2 and Jr.2 since they come equipped with a sam2695 IC from Dream. A toggle to PSG sound can be done so that the original K and Jr. can also participate, albeit with simpler sound. A demo mode of the tune can be activated with F5. Win with a perfect score while you play the main mode (F1) and get a special reward!
