calibration_session.h
Two-point joystick calibration as a state machine (pure C++20, natively tested).

control_status.h
Read-only view of the controller state for the HUD and stats line.

hud::speed_name
const char * speed_name(uint8_t speed)
Wire name of ControlStatus::speed: slow (0), normal (1) or fast (2); anything else reads as normal.
Definition reply_json.cpp:126

hud::kReplySize
constexpr size_t kReplySize
Buffer size that always holds a full reply.
Definition reply_json.h:27

hud::cal_state_name
const char * cal_state_name(aiming::CalState st)
Wire name of a calibration state: idle, point1, point2, done or failed.
Definition reply_json.cpp:108

hud::format_reply
size_t format_reply(const ReplyInput &in, char *out, size_t size)
Writes the NUL-terminated JSON reply into out and returns its length (without the NUL).
Definition reply_json.cpp:86

ControlStatus
Snapshot of the controller, published once per control pass.
Definition control_status.h:17

TrackSnapshot
Definition track_snapshot.h:14

hud::ReplyInput
Inputs of one reply. Null pointers mean that part is not available.
Definition reply_json.h:30

hud::ReplyInput::status
const ControlStatus * status
Controller state; null omits the controller keys and "vw".
Definition reply_json.h:32

hud::ReplyInput::viewers
uint32_t viewers
/stream viewers connected (0 to 2), sent as "vw" with the status keys.
Definition reply_json.h:33

hud::ReplyInput::track
const TrackSnapshot * track
Tracker output; null sends the fixed no-detection fallback.
Definition reply_json.h:31

track_snapshot.h
Plain copies of the tracker output and detection timings, safe to hand across tasks.
