On some HD44780 boards (eg the Keyestudio LCD1602 expansion shield), the RW pin isn't brought out and is permanently grounded. This means that the board can't be read from, and in particular the busy status can't be read. This patch adapts the package to work with boards like these. To signal this to the package, set the RW pin to machine.NoPin. The package will then disallow all reading and use adjustable timing based writing. The timing can be adjusted the configuration.
TinyGo Drivers
This package provides a collection of hardware drivers for devices 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)
}
}
