Interactive Round-Board Map

Select a rectangular hotspot on the round device. Each explains player perception, implementation and project evidence. Positions are functional rather than exact PCB coordinates.

466

SELECTED COMPONENT / SCREEN

CO5300 round AMOLED

PLAYER-FACING ROLE

The shared 466×466 touch/display surface; every primary action must remain inside the visible circle.

IMPLEMENTATION

QSPI + RGB565. Web and firmware use 1:1 logical pixels without scaling or interpolation.

VALIDATION EVIDENCE

Panel driver 2.1.0 initializes; dual-canvas refresh and six fixed frames achieve 100% palette parity.

Round-screen zones

Radius	Role	Typical input
0–168	Main content core	Tap, hold, STAR/SHOP action
168–184	Content buffer	Visual clearance and thumb protection
184–204	High-frequency circular controls	Bottom entry, orbit, card
185–233	Edge ownership zone	Page rotation and bezel feel
218	Visual safe radius	Worst-case bounds for text and primary art

Touch zones may overlap visual radii, but ownership is unique. Geometry at down classifies the gesture and later movement cannot casually switch systems.

Components mapped to play

• AMOLED + Touch: the entire page topology and gesture grammar, not merely display and click.
• IMU: continuous core parallax and STAR RUSH rather than a shake easter egg.
• RTC + NVS: trustworthy offline rewards and power-loss recovery.
• PMIC + PWR: settings, ambient and safe shutdown as a device state machine.
• Audio: short feedback that never becomes the only information channel.
• USB Serial/JTAG: development plus evidence capture for performance, touch, saves and faults.

Physical capability versus implemented feature

Official hardware imagery establishes what exists on the board. The map only claims what this project uses. microSD and microphone hardware exist but are not mounted as game features in this phase.
