Type	Name
uint16_t	syn_rc_curve_apply (uint16_t input_us, const SYN_RCCurve_Config * config) Apply deadband, exponential response, and dual-rate scaling to raw RC channel (1000..2000 us).

Detailed Description¶

Provides stick input response shaping for drones/RC models: * Deadband filtering: Ignores micro-stick jitter around neutral center (1500 us +/- deadband). * Exponential curve: y = (1 - expo) * x + expo * x^3 (softens center stick precision). * Dual Rate: Scales output range (0..100%).

All operations use Q16.16 fixed-point arithmetic. Zero float / zero heap.

uint16_t syn_rc_curve_apply (
    uint16_t input_us,
    const SYN_RCCurve_Config * config
)

Parameters:

input_us Raw input pulse width in microseconds (1000..2000 us).
config Pointer to RC curve configuration.

Returns:

Scaled & shaped output in microseconds (clamped 1000..2000 us).
