# googly — Decisions
|
|
|
|
- 2026-07-11: Big procedural face over pixel-art sprite creature — reads as alive
|
|
from desk distance, needs zero art assets, and partial-region redraw sidesteps
|
|
the 8-bit bus being too slow for full-screen animation.
|
|
- 2026-07-11: Light mood state (b) over pure toy (a) or full Tamagotchi (c) —
|
|
(a) goes stale, (c)'s neglect mechanic fights weekends (always-dying pet =
|
|
guilt, not cute).
|
|
- 2026-07-11: Mega 2560 as target — 256KB flash / 8KB RAM vs UNO's 32K/2K which
|
|
graphictest already fills to 98%. Firmware backed up before overwrite
|
|
(`../backups/mega-*-flash.hex`).
|
|
- 2026-07-11: No SD dependency — SD on this shield needs soft-SPI on the Mega
|
|
(pins 10-13 aren't Mega hardware SPI) and the face doesn't need assets anyway.
|
|
- 2026-07-11: Touch used only as tap/hold/pressure, not calibrated x/y — poke and
|
|
pet don't need position, which makes per-shield resistive calibration
|
|
unnecessary. Ghost-touch guard: pressure window + 2 consecutive samples.
|
|
|
|
## Deferred / Rejected
|
|
|
|
- Serial-dashboard generic firmware — separate idea, better fit for the
|
|
Leonardo/UNO (native USB on Leonardo). Not part of googly.
|
|
- RTC / real day-night cycle — no RTC on board; sleep is inactivity-based.
|
|
Revisit only if a DS3231 module shows up.
|
|
- Sound (piezo chirps) — no free pin budget to fight the shield over; also a
|
|
desk toy at work that beeps is a desk toy that gets unplugged.
