Package embd provides a superheroic hardware abstraction layer for doing embedded programming
|
2014-03-23 15:47:58 +05:30
|
|
|
on supported platforms like the Raspberry Pi and BeagleBone Black. Most of the examples below
|
|
|
|
will work without change (i.e. the same binary) on all supported platforms. How cool is that?

Although samples are all present in the samples folder, we will show a few choice examples here.

Use the LED driver to toggle LEDs on the BBB:
|
2013-12-09 02:49:39 +05:30
|
|
|
|
2014-03-23 15:47:58 +05:30
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
...
|
|
|
|
embd.InitLED()
|
|
|
|
defer embd.CloseLED()
|
|
|
|
...
|
|
|
|
led, err := embd.NewLED("USR3")
|
|
|
|
...
|
|
|
|
led.Toggle()
|

|
|
|
|
2014-03-23 15:47:58 +05:30
|
|
|
Even shorter while prototyping:
|
2013-12-09 02:49:39 +05:30
|
|
|
|
2014-03-23 15:47:58 +05:30
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
...
|
|
|
|
embd.InitLED()
|
|
|
|
defer embd.CloseLED()
|
|
|
|
...
|
|
|
|
embd.ToggleLED(3)
|

BBB + PWM:
|
2014-03-28 08:39:36 +05:30
|
|
|
|
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
...
|
|
|
|
embd.InitGPIO()
|
|
|
|
defer embd.CloseGPIO()
|
|
|
|
...
|
|
|
|
pwm, _ := embd.NewPWMPin("P9_14")
|
|
|
|
defer pwm.Close()
|
|
|
|
...
|
|
|
|
pwm.SetDuty(1000)
|
|
|

Control GPIO pins on the RaspberryPi / BeagleBone Black:
|
2013-12-09 02:49:39 +05:30
|
|
|
|
2014-03-23 15:47:58 +05:30
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
...
|
|
|
|
embd.InitGPIO()
|
|
|
|
defer embd.CloseGPIO()
|
|
|
|
...
|
|
|
|
embd.SetDirection(10, embd.Out)
|
|
|
|
embd.DigitalWrite(10, embd.High)
|
|
|
|
|
|
|
|
Could also do:
|
|
|
|
|
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
...
|
|
|
|
embd.InitGPIO()
|
|
|
|
defer embd.CloseGPIO()
|
|
|
|
...
|
|
|
|
pin, err := embd.NewDigitalPin(10)
|
|
|
|
...
|
|
|
|
pin.SetDirection(embd.Out)
|
|
|
|
pin.Write(embd.High)
|
|
|
|
|
|
|
|
Or read data from the Bosch BMP085 barometric sensor:
|
|
|
|
|
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
import "github.com/kidoman/embd/sensor/bmp085"
|
|
|
|
...
|
|
|
|
bus := embd.NewI2CBus(1)
|
|
|
|
...
|
|
|
|
baro := bmp085.New(bus)
|
|
|
|
...
|
|
|
|
temp, err := baro.Temperature()
|
|
|
|
altitude, err := baro.Altitude()
|
|
|
|
|
|
|
|
Even find out the heading from the LSM303 magnetometer:
|
|
|
|
|
|
|
|
import "github.com/kidoman/embd"
|
|
|
|
import "github.com/kidoman/embd/sensor/lsm303"
|
|
|
|
...
|
|
|
|
bus := embd.NewI2CBus(1)
|
|
|
|
...
|
|
|
|
mag := lsm303.New(bus)
|
|
|
|
...
|
|
|
|
heading, err := mag.Heading()
|
|
|
|
|
|
|
|
The above two examples depend on I2C and therefore will work without change on almost all
|
|
|
|
platforms.
