## Summary * **What is the goal of this PR?** Fixes #2402. On the X3, the "Time to Sleep" picker's 5-minute side buttons were inverted (left increased, right decreased) and the on-screen legend didn't match the physical buttons. * **What changes are included?** * Flip the large-step (±5 min) direction on X3 so the left side button decreases and the right increases, matching the layout. X4 is unchanged. * Add a device-specific step-hint string (`STR_SLEEP_TIMER_STEP_HINT_X3`) selected via `gpio.deviceIsX3()`. X3 shows `+/-: 1 min Side buttons: 5 min`; X4 keeps the original `Left/Right: 1 min Up/Down: 5 min`. * Same fix applied to both slider pickers that read the raw up/down side buttons: the Time-to-Sleep picker and the "Go to %" picker (`EpubReaderPercentSelectionActivity`), each with its own X3 hint string (`STR_SLEEP_TIMER_STEP_HINT_X3`, `STR_PERCENT_STEP_HINT_X3`). ## Additional Context * **Root cause:** the X3's side buttons sit one on each edge of the screen (power on top), whereas the X4 has a vertical up/down rocker on the right edge. So `BTN_UP` is physically the *left* button on X3 but the *top* button on X4. The picker mapped up→+5 / down→−5 unconditionally, which reads naturally on the X4 rocker but inverted on the X3's left/right buttons. The static legend ("Up/Down: 5 min") had the same X3-only mismatch. * The codebase already detects the device at runtime and handles this layout difference elsewhere (e.g. `LyraTheme::drawSideButtonHints` draws "Up on left, Down on right" for X3), so this reuses the same `gpio.deviceIsX3()` signal. * Swept the codebase for other side-button sliders: `ClockOffsetActivity` already uses the `Next/Previous` (`ButtonNavigator`) abstraction, which resolves to left=decrement / right=increment on X3, so it needs no change. List/page navigation (Wi-Fi, KOReader sync, BMP viewer) and the keyboard cursor are also unaffected. The two slider pickers above were the only ones using raw up/down. * **X4 is untouched** — same direction, same legend wording as before. * **Tested on X3 hardware:** left side button now decreases, right increases, and the legend matches. X4 not yet tested on device (no unit on hand); its behaviour and strings are unchanged from master. * **Translations:** the new `STR_SLEEP_TIMER_STEP_HINT_X3` and `STR_PERCENT_STEP_HINT_X3` were added to all 26 languages, but the non-English ones are AI-generated and would benefit from a native-speaker pass — particularly Hebrew (RTL ordering with a leading `+/-`), Kazakh, and Vietnamese. --- ### AI Usage Did you use AI tools to help write this code? _**YES**_ --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
This directory is intended for project specific (private) libraries.
PlatformIO will compile them to static libraries and link into the executable file.
The source code of each library should be placed in a separate directory
("lib/your_library_name/[Code]").
For example, see the structure of the following example libraries `Foo` and `Bar`:
|--lib
| |
| |--Bar
| | |--docs
| | |--examples
| | |--src
| | |- Bar.c
| | |- Bar.h
| | |- library.json (optional. for custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html
| |
| |--Foo
| | |- Foo.c
| | |- Foo.h
| |
| |- README --> THIS FILE
|
|- platformio.ini
|--src
|- main.c
Example contents of `src/main.c` using Foo and Bar:
```
#include <Foo.h>
#include <Bar.h>
int main (void)
{
...
}
```
The PlatformIO Library Dependency Finder will find automatically dependent
libraries by scanning project source files.
