#Quick Start

///|
fn main {
  try {
    let pid = @apple_silicon_accelerometer.start_sensord_background()
    @apple_silicon_accelerometer.sleep_seconds(1)
    match @apple_silicon_accelerometer.accel_latest() {
      Some((total, x, y, z)) =>
        println("accel total=\{total} xyz=(\{x}, \{y}, \{z})")

#Install

moon add oboard/apple_silicon_accelerometer

#Run Example

sudo moon run example

#API

#Parse helpers

• parse_imu_report(report : Bytes) -> (Int, Int, Int)
• parse_lid_angle(report : Bytes) -> Float?

#Sensor daemon control

• run_sensord() -> Unit raise
• start_sensord_background() -> Int raise
• stop_sensord_background(pid : Int) -> Unit
• sleep_seconds(seconds : Int) -> Unit

#Live snapshots

• accel_latest() -> (total : Int, x : Int, y : Int, z : Int)?
• gyro_latest() -> (total : Int, x : Int, y : Int, z : Int)?
• lid_latest() -> (total : Int, angle : Float)?
• als_latest_words() -> (total : Int, w0 : Int, w1 : Int, w2 : Int, w3 : Int)?

#Notes

• Target platform: macOS + Apple Silicon.
• Backend: native.
• If you run without sudo, APIs that start sensord will raise an error.
