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.
