Michael Traver e27c424b7b mcp9808: Fix conversions between temperature and bits (#403 ) The datasheet (http://ww1.microchip.com/downloads/en/DeviceDoc/25095A.pdf) says that negative temperatures are stored in two's complement. See page 22 for alert registers and pages 24-25 for the ambient temperature register. However, the code currently assumes negative values are stored in a sign-and-magnitude representation. Fix this to handle two's complement values correctly. For register bits to temperature conversion this implementation follows the datasheet, but the code in the datasheet isn't quite right -- it should be `temp - 256` instead of `256 - temp` -- but the fact that the 256 figure is in Microchip's code backs up the idea stated in the text that negative values are in two's complement. Others seem to agree that this is correct: https://electronics.stackexchange.com/a/244826 For temperature to bits conversion this implementation relies on the fact that Go also uses two's complement. I've added a long comment in the code about this.		7 years ago

Example

Blink a LED:

package main

import (
    "time"
    "periph.io/x/periph/conn/gpio"
    "periph.io/x/periph/host"
    "periph.io/x/periph/host/rpi"
)

func main() {
    host.Init()
    t := time.NewTicker(500 * time.Millisecond)
    for l := gpio.Low; ; l = !l {
        rpi.P1_33.Out(l)
        <-t.C
    }
}
