SIM_EINK=landscape|portrait builds the e-ink firmware for the browser, drawn by the same EinkGfxDisplay as the panel. index.html and mesh.html pick a build from the URL. The simulated sensors get a GPS switch, so the UI's GPS toggle works. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

// SensorManager subclass wiring the sim's already-existing

// SimLocationProvider (SimLocationProvider.h) into the real

|
// getLocationProvider() hook -- the base SensorManager (previously used
|
|
// as-is in target.cpp) always returns NULL there (see
|
|
// SimLocationProvider.h's own comment on this exact gap), so on-device
|
|
// screens that check "do I have a GPS fix" (CompassScreen.h,
|
|
// NearbyScreen.h) never saw a fix even after sim_location_set() was
|
|
// called, even though the *advertised* position (sensors.node_lat/lon)
|
|
// already worked. Also adds one representative JS-settable environment
|
|
// telemetry channel (temperature) to prove the querySensors() mechanism --
|
|
// same channel-numbering convention as the real
|
|
// src/helpers/sensors/EnvironmentSensorManager.cpp: GPS on
|
|
// TELEM_CHANNEL_SELF, each other active sensor on the next channel.
|
|
//
|
|
// getLocationProvider()/querySensors() are declared here but DEFINED in
|
|
// target.cpp, not inline -- they need SimLocationProvider.h's complete
|
|
// type (for the LocationProvider* upcast, and to call
|
|
// sim_location_provider()), and SimLocationProvider.h in turn needs THIS
|
|
// class's complete type for its own `extern SimSensorManager sensors;`
|
|
// declaration (see that file's comment) -- pulling SimLocationProvider.h
|
|
// in here too would make the two headers mutually dependent on each
|
|
// other's complete type with no valid include order. target.cpp already
|
|
// includes target.h, which includes both in the one order that works
|
|
// (this file first, then SimLocationProvider.h), so it's the natural
|
|
// place for the bodies that need both.

// Deliberately doesn't fake any of the ~15 real I2C sensor chip drivers
|

// (BME280/INA219/etc, EnvironmentSensorManager.cpp) -- those are

|
// hardware-specific and out of scope; one JS-settable channel is enough to
|
|
// prove the mechanism and is trivially extended later if a specific sensor
|
|
// type turns out to matter for a demo.
