Challenges: + 6-channel audio + Fitting it all in 48k (want to avoid disk routines if can) + Printing the ASCII art simple code (takes longer than 50Hz) ASCII Art Size The ASCII art is roughly 7k. You can LZ4 compress it and decompress on the fly, saving 3k or so even when factoring in the decompression code. The problem is decompression is slower (pauses the music) and can't be run at the same time as the music decompression is happening unless we duplicate a lot of code. May revisit if we need the room. Goal: Binary fits in 16k (16384 bytes) note size (bytes) --------------------- ------ initial music player: 2078 add raw ascii art: 9142 add 3-channel music+lyrics,then slim a bit: 18787 initial 40 col support: 18864 have art loading properly 40col: 18910 lz4 encode the ascii art: 15529 revert because lz4 code not re-entrant: 18910 Memory Map Lowmem: 4k Code: 16k (8k=audio, 5k=lyrics, 3k=art) Sound buffers: 14k Sound buffer2: 14k?
