New pico-cp/ — a CircuitPython port of the PM_K-1 firmware so the Pico mounts as a
CIRCUITPY drive carrying its code + tracks (the MicroPython pico/main.py stays the
simple fallback):
- pico-cp/code.py: displayio BusDisplay driving ST7796 via a custom init_sequence;
smooth anti-aliased text via displayio Bitmap+Palette (reuses the baked font blobs);
vectorio rects for dots/buttons; DIY GT911 touch (16-bit regs, edge-detected);
pwmio buzzer, analogio joystick, digitalio buttons, optional neopixel RGB; the
polymeter engine on a time.monotonic_ns scheduler. Reads /programs.json (falls back
to baked defaults); CircuitPython auto-reloads on file change.
- pico-cp/programs.json: the 23 default grooves. pico-cp/README.md: flash + calibrate.
- build.sh/deploy.sh: bundle + serve /pm_k1_circuitpy.zip. info-kit.html: experimental
'CircuitPython edition — USB drive' section.
Verified in CPython (stubbed displayio): init sequence well-formed, parser handles the
grooves incl. (3,8) euclid + @-4 gain, and code.py's actual make_text renders identical
smooth AA text. Hardware bits (panel/touch/MIDI) await on-board testing.

A user dropped main.py onto the RPI-RP2 BOOTSEL drive (which only accepts a .uf2)
and it vanished on reboot. Clarify in pico/README.md and info-kit.html that
flashing is two distinct steps: (1) drag-and-drop the MicroPython .uf2, then
(2) copy main.py over USB serial with Thonny/mpremote — the Pico is not a USB
drive once MicroPython is running.

A new, first-actually-buildable form factor for the 52Pi EP-0172 "Pico Breadboard
Kit Plus" (Raspberry Pi Pico; 3.5" ST7796 320x480 cap-touch via GT911, PSP
joystick on ADC0/1, WS2812 RGB on GP12, buzzer GP13, buttons GP14/15):
- pico/main.py — one self-contained MicroPython file: ST7796 direct-draw driver,
GT911 touch (16-bit register addressing), WS2812 RGB (neopixel), PWM buzzer,
ADC joystick, buttons. It parses the project's own program-string language
(verified against the web engine's semantics) and runs a non-blocking
ticks_us scheduler with an on-screen touch UI. CONFIG flags cover panel /
colour / touch / joystick calibration. pico/README.md has flashing +
calibration steps.
- kit.html — lean widget that mirrors the firmware's on-screen UI (portrait
320x480 canvas) plus a joystick / RGB / buzzer / A-B buttons; plays via the
shared engine. info-kit.html — the real EP-0172 pinout, a parts list
(~$45 incl. Pico) and the firmware to flash (downloads /pico-main.py, links
the README + source).
- Landing + embed page list the Kit; build.sh/deploy.sh build the two pages and
serve pico/main.py as /pico-main.py for download.
