Settings¶
The Settings page lets you configure language, display appearance, servo parameters, and view system information. All changes are saved automatically when you leave the page.
Language¶
Select your preferred interface language:
- English
- Deutsch (German)
- Français (French)
- Español (Spanish)
- Italiano (Italian)
- Nederlands (Dutch)
- Čeština (Czech)
The page refreshes immediately when you change the language.
Display¶
Brightness¶
Adjust the display backlight brightness (10–100%).
Background Color¶
Choose a background color preset:
- Light Gray
- White
- Light Blue
- Light Green
- Cream
Servo¶
Configure default PWM parameters for all servos. The servo driver uses these values as boundaries.
Protocol Presets¶
Quickly apply common servo timing standards:
| Protocol | PWM Min | Center | PWM Max | Frequency |
|---|---|---|---|---|
| Standard | 1000 µs | 1500 µs | 2000 µs | 50 Hz |
| Extended | 500 µs | 1500 µs | 2500 µs | 50 Hz |
| Sanwa | 760 µs | 1520 µs | 2280 µs | 50 Hz |
| Futaba | 920 µs | 1520 µs | 2120 µs | 50 Hz |
| Digital Fast | 500 µs | 1500 µs | 2500 µs | 333 Hz |
| Custom | (user-defined) |
Selecting a preset automatically fills in the PWM values and frequency. If you manually change any slider, the protocol switches to Custom.
Frequency¶
Choose the PWM update rate:
- 50 Hz – Standard analog servos
- 333 Hz – High-speed digital servos
Warning
Using 333 Hz with analog servos may cause erratic behavior or damage.
PWM Values¶
Fine-tune the pulse widths with sliders:
| Setting | Range | Description |
|---|---|---|
| PWM Min | 500–1500 µs | Minimum pulse width (full left) |
| PWM Center | 1000–2000 µs | Neutral position |
| PWM Max | 1500–2500 µs | Maximum pulse width (full right) |
Per-Servo Step Size¶
Each of the 6 servo channels has its own Step slider (1–100 µs). This controls how much the PWM changes per encoder click in Manual mode on the Servo Tester page.
- Servo Step 1 through Servo Step 6
Use smaller steps for precise positioning or larger steps for quick sweeps.
Reset Button¶
The Reset Servo Steps button restores all per-servo step values to the default (10 µs).
System¶
Displays read-only information:
| Field | Description |
|---|---|
| Firmware | Application version (e.g., 1.0.0) |
| LVGL | GUI library version (e.g., 9.4.0) |
Navigation¶
Use the encoder to scroll through settings and adjust values:
| Action | Effect |
|---|---|
| Rotate | Scroll / adjust slider value |
| Press | Open dropdown / confirm selection |
