Fitting everything in a PlatformIO project?

[magnetrwn]

Hi,

I'm working on adapting your MOD player for a learning hobby board design I made at tinyclock002-test, to make some patterns and ideally keep it as a little alarm clock to play MOD tracker alarms.

1. Is the total footprint in flash around the 11kB mark including your test MOD building with ch32fun with maximum optimization? Currently my build without MOD tracker fits in 9.5kB, not sure how easy it will be to trim further as the build is already -Os
2. Should I move to using ch32fun directly instead of PlatformIO for space constraints?
3. I believe MOD tracker files can't really be compressed much, the only alternative I see having is using an additional expansion over I2C/UART (I also used the A4M6 alternative, so I don't have access to SPI.) Is it feasible in your opinion? Cost/part wise it's probably better to just jump to the V006 as you did as well.

Thanks, and cool project!
