New page: full LED indicator reference (firmware RA2E1260726001+, charging/charged now distinguish system on/off)

新页面

'''Photonicat 2''' has a single two-colour indicator LED (red + green). Yellow/orange is produced by lighting both colours together; there is no blue.

The indicator follows a MacBook-style scheme:
* '''Colour tells you the charge state''' — 🟠 yellow = charging, 🟢 green = charged.
* '''Motion tells you the machine state''' — breathing = system running, steady = system off.

Applies to firmware '''RA2E1260726001''' and later. Earlier firmware did not distinguish system on/off while charging or charged.

==Full state table==

Battery thresholds are firmware defaults and can be overridden by the host. Values are for the 2S pack: full 8280 mV, low warning 6500 mV, minimum boot 6600 mV, hard shutdown 6300 mV.

{| class="wikitable"

|}

==Service and transitional states==

These override the states above.

{| class="wikitable"
! State !! Colour !! Pattern !! Timing
|-
| Shutting down || 🟢 Green || Blink || ≈0.5 s on / 1.5 s off
|-
| Firmware download mode || 🟠 Yellow || Fast blink || ≈0.5 s period
|-
| Reset / factory restore mode || 🟠 Yellow || Slow blink || ≈1 s period
|}

==Charge limit==

If a charge limit is configured (for example 80 %), the charger is switched off once the pack reaches it. Charge current drops to zero, so the device treats this as fully charged and shows 🟢 '''green'''. The pack then powers the load and slowly discharges until it falls below the resume threshold, at which point charging restarts and the indicator returns to 🟠 yellow. Each transition is delayed by about 10 seconds.

==Notes==

* Breathing runs at a lower peak brightness (25 % duty) than steady (50 %), so a breathing indicator looks dimmer than a steady one of the same colour.
* 🔴 Red is only ever used for low battery, and stops after three flashes rather than flashing continuously.
* The indicator can be disabled entirely through the host protocol, in which case it stays off in all states.

Photonicat 2 LED Indicator - 版本历史

C2h2：​Point cross-links at the renamed SOC pages directly instead of via redirects

C2h2：​Move the SOC cross-link above the category tag

C2h2：​Link to the coulomb-counter/SOC explainer

C2h2：​Low-battery red now flashes continuously (firmware RA2E1260726003+) instead of stopping after 3 flashes

C2h2：​Add 'Low battery red light' section: 6500 mV trigger, 60 s delay, stops after 3 flashes, and only 200 mV above the 6300 mV shutdown point

C2h2：​改用 -v2 文件名，绕过浏览器缓存中旧的深色背景动画

C2h2：​更新链接指向重命名后的页面标题（Photonicat 2 …）

C2h2：​Add animated LED indicator illustrations (GIF, timing from the firmware sine_q16 table)

C2h2：​Link to the Sound Guide page

C2h2：​New page: full LED indicator reference (firmware RA2E1260726001+, charging/charged now distinguish system on/off)
