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 github.com/hybridgroup/gobot/... && go install github.com/hybridgroup/gobot/platforms/megapi
How to Use
package main
import (
"github.com/hybridgroup/gobot"
"github.com/hybridgroup/gobot/platforms/megapi"
"time"
)
func main() {
gbot := gobot.NewGobot()
// use "/dev/ttyUSB0" if connecting with USB cable
// use "/dev/ttyAMA0" on devices older than Raspberry Pi 3 Model B
megaPiAdaptor := megapi.NewMegaPiAdaptor("megapi", "/dev/ttyS0")
motor := megapi.NewMotorDriver(megaPiAdaptor, "motor1", 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,
)
gbot.AddRobot(robot)
gbot.Start()
}
