go-servo-picobber

A golang port of the python driver for Geekroo's PWM Servo PiCobber.

The PWM Servo Driver PiCobber Raspberry Pi HAT has the ability to drive up to 16 servos or PWM outputs with over 12C with only 2 pins. The PWM controller on-board drives all the 16 channels and it does not require any additional Raspberry Pi processing overhead.

Install the driver

go get github.com/3rubasa/go-servo-picobber

Example

package main

import (
    "log"
    "time"

    "github.com/3rubasa/go-servo-picobber"
)

func main() {
    servoMin := 150 // Min pulse length out of 4096
    servoMax := 600 // Max pulse length out of 4096

    sv, err := servo.NewServo()
    if err != nil {
        log.Println(err)
    }
    sv.SetPwmFreq(50) // Set frequency to 60 Hz
    for {
        // Change speed of continuous servo on channel O
        sv.SetPwm(0, 0, servoMin)
        time.Sleep(1 * time.Second)
        sv.SetPwm(0, 0, servoMax)
        time.Sleep(1 * time.Second)
    }
