The current code interprets the 'century' flag as the year 2100. However the DS3231 hardware does not incorporate this flag in its leap year calculation, so will incorrectly consider the year 2100 as a leap year and increment from 2100-02-28 to 2100-02-29 instead of the correct 2100-03-01. The 'century' bit is not useful for anything as far as I can tell. But instead of removing the code that uses the 'century' bit, I thought it would be less intrusive to just document the current behavior.
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)
}
}
