MegaPi
The MegaPi is a motor controller by MakeBlock that is compatible with the Raspberry Pi.
The code is based on a python implementation that can be found here.
How to Install
go get -d -u gobot.io/x/gobot/...
How to Use
package main
import (
"gobot.io/x/gobot"
"gobot.io/x/gobot/platforms/megapi"
"time"
)
func main() {
// use "/dev/ttyUSB0" if connecting with USB cable
// use "/dev/ttyAMA0" on devices older than Raspberry Pi 3 Model B
megaPiAdaptor := megapi.NewAdaptor("/dev/ttyS0")
motor := megapi.NewMotorDriver(megaPiAdaptor, 1)
work := func() {
speed := int16(0)
fadeAmount := int16(30)
gobot.Every(100*time.Millisecond, func() {
motor.Speed(speed)
speed = speed + fadeAmount
if speed == 0 || speed == 300 {
fadeAmount = -fadeAmount
}
})
}
robot := gobot.NewRobot("megaPiBot",
[]gobot.Connection{megaPiAdaptor},
[]gobot.Device{motor},
work,
)
robot.Start()
}
