## Key Implementation Details
|
|
|
|
### InputManager
|
|
- 4 GPIO inputs (32, 33, 25, 26) with pull-up, interrupt on CHANGE
|
|
- Debounce: 175ms
|
|
- Sequence detection: 700ms timeout timer — accumulates button presses into a string
|
|
- "1" = button 1 single, "11" = button 1 double-tap, etc.
|
|
|
|
### Led (BLE Panel Client)
|
|
- Connects by MAC address (passed as constructor string)
|
|
- Uses `BLE_ADDR_TYPE_RANDOM` for connection
|
|
- Single write characteristic for commands
|
|
- Slot command: 20-byte packet with offset calculation from slot_id 61
|
|
- **The slot command doesn't work on current panel — needs re-reverse-engineering**
|
|
|
|
### Wled (WiFi WLED Client)
|
|
- Resolves via mDNS or direct IP
|
|
- Fetches `/presets.json` on connect, builds name→ID map
|
|
- Switches presets via POST to `/json/state` with `{"ps":"<id>"}`
|
|
- Actions mapped by preset name: "LEFT", "RIGHT", "BRAKE", "NEUTRAL"
|
|
|
|
### Inmotion V13
|
|
- BLE connection to EUC
|
|
- Parses speed data from notifications
|
|
- Fires BRAKE event when decelerating, NEUTRAL when stable
|
|
- Also supports HORN and TOGGLE_LIGHT commands
|
|
|
|
### WiFi
|
|
- SSID: SASI, password: h3ll0w1f1
|
|
- Hostname: "controller"
|
|
- mDNS enabled
|
|
- BLE/WiFi coexistence: `ESP_COEX_PREFER_BALANCE`
|
|
|
|
### Build
|
|
```bash
|
|
cd /home/seb/glove
|
|
pio run -e upesy_wroom # build
|
|
pio run -e upesy_wroom -t upload # flash
|
|
```
