Enumeration Type Documentation

FilterPreset

enum class FilterPreset : uint8_t

strong

Presets for the adaptive velocity/angle filter (Dynamic Filter System).

Maps to datasheet Figure 17 "Angular Velocity Measurement Filter Parameters". Lower K = less noise at standstill, higher latency; higher K = more noise, faster response. Use SetFilterPreset() for one-call configuration.

Enumerator
LowNoise	Minimum noise at standstill (~5.8 °/s RMS). Best for low-speed or static use.
Balanced	Balanced noise vs response (~8–20 °/s). Good default for most applications.
HighBandwidth	Maximum bandwidth, highest standstill noise (~245 °/s). Use when speed matters.

FrameFormat

enum class FrameFormat : uint8_t

strong

Supported SPI frame formats for AS5047U communication.

Enumerator
SPI_16	16-bit frames (no CRC, high-throughput mode)
SPI_24	24-bit frames (includes 8-bit CRC for reliability)
SPI_32	32-bit frames (includes 8-bit CRC and 8-bit pad for daisy-chain)
