WTPA Firmware Rev 3 Released!
OK. I finished shoe-horning necessary functions into this beast. Somebody tell me something that needs to change or this beta becomes legit by tomorrow.
There are a whopping 12 bytes left in memory, and the OS has had a lot of fat trimmed.
Here’s beta 4 (final):
And here’s the R3 changelog, so if you don’t know, now you know:
Firmware Version 0x03:
Wed Sep 2 09:37:49 CDT 2009
— Hardcoded explicit bank start address variables into define statements. They are constants in our current system; this will prevent them from being overwritten, save us some RAM and some cycles.
— Sample Start / Window / Endpoint editing, realtime adjustment. Samples with will reverse when the start point is put after the endpoint.
— Separated the “bail” command for FX and loop adjustments in MIDI
— Re-number MIDI CCs
— Added MIDI option to edit samples with wide range or tighter resolution (editing pot is an 8-bit value, MIDI is 7)
— Added “edit mode” which sucks. But allows you to stop holding down three buttons while you edit a sample.
— Removed some un- or underused softclock (timer) and Uart functions — we’re running low on flash memory.
— Divided AudioHandler routines into bank-specific routines for ISR speed BUT
–> this means we are way over memory. So, got rid of intro sequence, debug mode, all sawtooth stuff, removed some timer functions, changed MIDI handling (don’t recognize bytes we don’t use anyway), changed LED blink functions (all blink times the same)
–> Also kilt the random number init code. Changed pinning in multiply-output mode.
