This commit adds support for the nrf52, which is a Cortex-M4 running at 64MHz. While implementing this, I discovered that the timings for AVR/16MHz and Cortex-M0 at 16MHz weren't quite right. They do work, but were slightly out of spec. So I fixed this as well.
TinyGo Drivers
This package provides a collection of hardware drivers for devices that can be used together with TinyGo.
Installing
go get github.com/tinygo-org/drivers
How to use
Here is an example in TinyGo that uses the BMP180 digital barometer:
package main
import (
"time"
"machine"
"github.com/tinygo-org/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.Temperature()
println("Temperature:", float32(temp)/1000, "ºC")
pressure, _ := sensor.Pressure()
println("Pressure", float32(pressure)/100000, "hPa")
time.Sleep(2 * time.Second)
}
}
