ImpedanceMode

enum ImpedanceMode : Enum<ImpedanceMode>

Electrode impedance measurement mode — config blob byte 0 (codes are the wire contract, shared with the BrainAccess C SDK). Non-OFF modes make the device inject a small AC test current through the bias electrodes at the given frequency; the device computes electrode impedance on-chip (Ohm's law, Z = Vpp / I) and streams it directly in kΩ.

Entries

OFF

HZ_7_8

7.8 Hz test wave. Measurable up to 250 Hz.

HZ_31_2

31.2 Hz test wave. Measurable up to 1000 Hz.

DR_DIV4

Test wave at sample_rate / 4: measurable at every rate.

Properties

active

val active: Boolean

Whether the impedance packet layout (24-bit absolute samples, device-computed kΩ) is in effect.

code

val code: Byte

entries

val entries: EnumEntries<ImpedanceMode>

Returns a representation of an immutable list of all enum entries, in the order they're declared.

name

val name: String

ordinal

val ordinal: Int

Functions

valueOf

fun valueOf(value: String): ImpedanceMode

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

values

fun values(): Array<ImpedanceMode>

Returns an array containing the constants of this enum type, in the order they're declared.
