Bigme Light Control v1.2.0

What's new

• Custom presets — the built-in Daytime / Reading / Bedtime presets are now editable: hold a preset in Quick presets to rename or delete it, and save your own presets from the current light values (they persist across restarts).
• Channel symbols — ❄️ cool and 🔥 warm now appear in the control dialog, notifications, status line, and gesture action names.
• Dialog steppers use your step size — the ± buttons follow the Step size setting instead of a fixed ±10.
• Smoother gestures — rapid swipe notifications are debounced into a single e-ink refresh.
• Sleep handling — saved light levels are cleared after resume, so a later off-then-suspend can't restore a stale value.
• Build tooling — make embed regenerates the embedded helper from helper/bigme_light.sh (this release fixes drift where the embedded copy lacked the set_both usage line); make release builds the install zip.

Install

1. Download bigmelight-v1.2.0.zip below.
2. Unzip so the folder lands at /sdcard/koreader/plugins/bigmelight.koplugin/.
3. Restart KOReader, open Bigme Light, and grant Magisk superuser when prompted.

Existing users: just overwrite the plugin folder — your presets and settings are kept.

Bigme Light Control v1.1.0

What's New in v1.1.0

🚀 Zero-Latency Direct Sysfs I/O

• On initialization and setup, permissions on the TI LM3630A sysfs nodes are configured (0666), allowing KOReader to read and write directly through Lua.
• Gesture latency drops from ~50ms to <1ms with zero process forks, eliminating UI stutter on rapid swipe gestures.
• Transparently falls back to the Magisk su helper if direct I/O is blocked by SELinux.

🔋 Power Management (Standby Battery Saver)

• Automatic suspend/resume lifecycle integration: turns off the LM3630A LEDs when the device enters sleep to prevent battery drain in standby.
• Automatically restores previous light levels when waking up.
• Can be toggled on/off via the menu (Turn off on sleep).

💡 E-Ink Friendly Touch Controls & Presets

• New interactive light dialog with responsive steppers (Cold +/-10, Warm +/-10) and quick presets.
• Instant presets:
  • ☀️ Daytime (Cold 80, Warm 0)
  • 📖 Reading (Cold 50, Warm 60)
  • 🌙 Bedtime (Cold 0, Warm 50)
  • 🌑 All off (0, 0)
• Registered new Dispatcher actions for gestures (bigme_preset_day, bigme_preset_read, bigme_preset_night).
• Separate modal for setting exact numeric values without forcing the software keyboard open.

🛠️ Code Health & Fixes

• onBigmeEinkCenter now calls os.execute directly, avoiding unread pipe file descriptors.
• Removed redundant driver reads during UI interactions.
• Check setup now displays the active hardware access mode (Direct vs Root fallback).

Bigme Light Control v1.0

Initial release of Bigme Light Control plugin for KOReader.

What it does

Control the Bigme HiBreak / B6 front light (cold and warm channels, 0-255) from KOReader using the menu or swipe gestures.

Highlights

• Menu: light control dialog, step size, all off, EinkCenter panel
• Gestures: increase/decrease cold or warm, toggle, dialog, all off
• Self-contained setup: the root helper is embedded in the plugin and installed through Magisk on first run
• Health checks: Check setup and Install / update helper report root, driver, and helper status
• Persistent: the helper survives reboots and auto-repairs if removed
• Toggle with memory: turning the light off remembers the last levels

Requirements

• Bigme HiBreak / B6 (LM3630A front-light driver)
• Root (Magisk) — see the Rooting Guide
• No external dependencies and no PC required after downloading the zip
