This type should be used whenever a sensor (or actuator?) works with a
temperature. For example, this commit changes the signature:
ReadTemperature() (int32, error)
to the following:
ReadTemperature() (drivers.Temperature, error)
I believe this is much clearer in intent. It also makes it trivial to
introduce common conversions. For example, there are already Celsius()
and Fahrenheit() methods to convert to the given units, as a floating
point. More units could be added as needed, for example a CelsiusInt().
TinyGo Drivers
This package provides a collection of hardware drivers for devices such as sensors and displays that can be used together with TinyGo.
Installing
go get tinygo.org/x/drivers
How to use
Here is an example in TinyGo that uses the BMP180 digital barometer:
package main
import (
"time"
"machine"
"tinygo.org/x/drivers/bmp180"
)
func main() {
machine.I2C0.Configure(machine.I2CConfig{})
sensor := bmp180.New(machine.I2C0)
sensor.Configure()
connected := sensor.Connected()
if !connected {
println("BMP180 not detected")
return
}
println("BMP180 detected")
for {
temp, _ := sensor.ReadTemperature()
println("Temperature:", float32(temp)/1000, "°C")
pressure, _ := sensor.ReadPressure()
println("Pressure", float32(pressure)/100000, "hPa")
time.Sleep(2 * time.Second)
}
}
