BH1750 ambient light sensor
=====================
[![Build Status](https://travis-ci.org/d2r2/go-bh1750.svg?branch=master)](https://travis-ci.org/d2r2/go-bh1750)
[![Go Report Card](https://goreportcard.com/badge/github.com/d2r2/go-bh1750)](https://goreportcard.com/report/github.com/d2r2/go-bh1750)
[![GoDoc](https://godoc.org/github.com/d2r2/go-bh1750?status.svg)](https://godoc.org/github.com/d2r2/go-bh1750)

BH1750 ([general specification](https://raw.github.com/d2r2/go-bh1750/master/docs/bh1750fvi-e-186247.pdf)) is a power effective ambient light sensor with spectral response close to human eye. Sensor returns measured ambient light value in lux units. Easily integrated with Arduino and Raspberry PI via i2c communication interface:
![image](https://raw.github.com/d2r2/go-bh1750/master/docs/bh1750.jpg)
Here is a library written in [Go programming language](https://golang.org/) for Raspberry PI and counterparts, which gives you in the output ambient light value (making all necessary i2c-bus interacting and values computing).
Golang usage
------------
```go
func main() {
// Create new connection to i2c-bus on 0 line with address 0x23.
// Use i2cdetect utility to find device address over the i2c-bus
i2c, err := i2c.NewI2C(0x23, 0)
if err != nil {
log.Fatal(err)
}
defer i2c.Close()
sensor := bh1750.NewBH1750()
resolution := bh1750.HighResolution
amb, err := sensor.MeasureAmbientLight(i2c, resolution)
if err != nil {
lg.Fatal(err)
}
log.Printf("Ambient light (%s) = %v lx", resolution, amb)
```
Getting help
------------
GoDoc [documentation](http://godoc.org/github.com/d2r2/go-bh1750)
Installation
------------
```bash
$ go get -u github.com/d2r2/go-bh1750
```
Troubleshooting
--------------
- *How to obtain fresh Golang installation to RPi device (either any RPi clone):*
If your RaspberryPI golang installation taken by default from repository is outdated, you may consider
to install actual golang manually from official Golang [site](https://golang.org/dl/). Download
tar.gz file containing armv6l in the name. Follow installation instructions.
- *How to enable I2C bus on RPi device:*
If you employ RaspberryPI, use raspi-config utility to activate i2c-bus on the OS level.
Go to "Interfacing Options" menu, to active I2C bus.
Probably you will need to reboot to load i2c kernel module.
Finally you should have device like /dev/i2c-1 present in the system.
- *How to find I2C bus allocation and device address:*
Use i2cdetect utility in format "i2cdetect -y X", where X may vary from 0 to 5 or more,
to discover address occupied by peripheral device. To install utility you should run
`apt install i2c-tools` on debian-kind system. `i2cdetect -y 1` sample output:

I2C-bus interaction of peripheral sensors with Raspberry PI embedded linux or respective clones
==============================================================================================
[![Build Status](https://travis-ci.org/d2r2/go-i2c.svg?branch=master)](https://travis-ci.org/d2r2/go-i2c)
[![Go Report Card](https://goreportcard.com/badge/github.com/d2r2/go-i2c)](https://goreportcard.com/report/github.com/d2r2/go-i2c)

[![MIT License](http://img.shields.io/badge/License-MIT-yellow.svg)](./LICENSE)
This library written in [Go programming language](https://golang.org/) intended to activate and interact with the I2C bus by reading and writing data.
Compatibility
-------------
Tested on Raspberry Pi 1 (model B), Raspberry Pi 3 B+, Banana Pi (model M1), Orange Pi Zero, Orange Pi One.
Golang usage
------------
```go
func main() {
// Create new connection to I2C bus on 2 line with address 0x27
i2c, err := i2c.NewI2C(0x27, 2)
if err != nil { log.Fatal(err) }
// Free I2C connection on exit
defer i2c.Close()
....
// Here goes code specific for sending and reading data
// to and from device connected via I2C bus, like:
_, err := i2c.Write([]byte{0x1, 0xF3})
if err != nil { log.Fatal(err) }
....
}
```
Tutorial
--------
My [repositories](https://github.com/d2r2?tab=repositories) contain quite a lot projects, which use i2c library as a starting point to interact with various peripheral devices and sensors for use on embedded Linux devices. All these libraries start with a standard call to open I2C-connection to specific bus line and address, than pass i2c instance to device.
In its turn, go-i2c use [go-logger](https://github.com/d2r2/go-logger) library to output debug and other notification's lines which produce all necessary levels of logging. You can manage what level of verbosity you would like to see, by adding call:
```go
// Uncomment/comment next line to suppress/increase verbosity of output
logger.ChangePackageLogLevel("i2c", logger.InfoLevel)
```
Once you put this call, it will decrease verbosity from default "Debug" up to next "Info" level, reducing the number of low-level console outputs that occur during interaction with the I2C bus. Please, find examples in corresponding I2C-driven sensors among my projects.
You will find here the list of all devices and sensors supported by me, that reference this library:
- [Liquid-crystal display driven by Hitachi HD44780 IC](https://github.com/d2r2/go-hd44780).
- [BMP180/BMP280/BME280 temperature and pressure sensors](https://github.com/d2r2/go-bsbmp).
- [DHT12/AM2320 humidity and temperature sensors](https://github.com/d2r2/go-aosong).
- [Si7021 relative humidity and temperature sensor](https://github.com/d2r2/go-si7021).
- [SHT3x humidity and temperature sensor](https://github.com/d2r2/go-sht3x).
- [VL53L0X time-of-flight ranging sensor](https://github.com/d2r2/go-vl53l0x).
- [BH1750 ambient light sensor](https://github.com/d2r2/go-bh1750).
- [MPL3115A2 pressure and temperature sensor](https://github.com/d2r2/go-mpl3115a2).
Getting help
------------
GoDoc [documentation](http://godoc.org/github.com/d2r2/go-i2c)
Troubleshooting
--------------
- *How to obtain fresh Golang installation to RPi device (either any RPi clone):*
If your RaspberryPI golang installation taken by default from repository is outdated, you may consider
to install actual golang manually from official Golang [site](https://golang.org/dl/). Download
tar.gz file containing armv6l in the name. Follow installation instructions.
- *How to enable I2C bus on RPi device:*
If you employ RaspberryPI, use raspi-config utility to activate i2c-bus on the OS level.
Go to "Interfacing Options" menu, to active I2C bus.
Probably you will need to reboot to load i2c kernel module.
Finally you should have device like /dev/i2c-1 present in the system.
- *How to find I2C bus allocation and device address:*
Use i2cdetect utility in format "i2cdetect -y X", where X may vary from 0 to 5 or more,
to discover address occupied by peripheral device. To install utility you should run
`apt install i2c-tools` on debian-kind system. `i2cdetect -y 1` sample output:
```

Package spew implements a deep pretty printer for Go data structures to aid in
debugging.
A quick overview of the additional features spew provides over the built-in
printing facilities for Go data types are as follows:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output (only when using
Dump style)
There are two different approaches spew allows for dumping Go data structures:
* Dump style which prints with newlines, customizable indentation,
and additional debug information such as types and all pointer addresses
used to indirect to the final value
* A custom Formatter interface that integrates cleanly with the standard fmt
package and replaces %v, %+v, %#v, and %#+v to provide inline printing
similar to the default %v while providing the additional functionality
outlined above and passing unsupported format verbs such as %x and %q
along to fmt
Quick Start
This section demonstrates how to quickly get started with spew. See the
sections below for further details on formatting and configuration options.
To dump a variable with full newlines, indentation, type, and pointer
information use Dump, Fdump, or Sdump:
spew.Dump(myVar1, myVar2, ...)
spew.Fdump(someWriter, myVar1, myVar2, ...)
str := spew.Sdump(myVar1, myVar2, ...)
Alternatively, if you would prefer to use format strings with a compacted inline
printing style, use the convenience wrappers Printf, Fprintf, etc with
%v (most compact), %+v (adds pointer addresses), %#v (adds types), or
%#+v (adds types and pointer addresses):
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Fprintf(someWriter, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(someWriter, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
Configuration Options
Configuration of spew is handled by fields in the ConfigState type. For
convenience, all of the top-level functions use a global state available
via the spew.Config global.
It is also possible to create a ConfigState instance that provides methods
equivalent to the top-level functions. This allows concurrent configuration
options. See the ConfigState documentation for more details.
The following configuration options are available:
* Indent
String to use for each indentation level for Dump functions.
It is a single space by default. A popular alternative is "\t".
* MaxDepth
Maximum number of levels to descend into nested data structures.
There is no limit by default.
* DisableMethods
Disables invocation of error and Stringer interface methods.
Method invocation is enabled by default.
* DisablePointerMethods
Disables invocation of error and Stringer interface methods on types
which only accept pointer receivers from non-pointer variables.
Pointer method invocation is enabled by default.
* DisablePointerAddresses
DisablePointerAddresses specifies whether to disable the printing of
pointer addresses. This is useful when diffing data structures in tests.
* DisableCapacities
DisableCapacities specifies whether to disable the printing of
capacities for arrays, slices, maps and channels. This is useful when
diffing data structures in tests.
* ContinueOnMethod
Enables recursion into types after invoking error and Stringer interface
methods. Recursion after method invocation is disabled by default.
* SortKeys
Specifies map keys should be sorted before being printed. Use
this to have a more deterministic, diffable output. Note that
only native types (bool, int, uint, floats, uintptr and string)
and types which implement error or Stringer interfaces are
supported with other types sorted according to the
reflect.Value.String() output which guarantees display
stability. Natural map order is used by default.
* SpewKeys
Specifies that, as a last resort attempt, map keys should be
spewed to strings and sorted by those strings. This is only
considered if SortKeys is true.
Dump Usage
Simply call spew.Dump with a list of variables you want to dump:
spew.Dump(myVar1, myVar2, ...)
You may also call spew.Fdump if you would prefer to output to an arbitrary
io.Writer. For example, to dump to standard error:
spew.Fdump(os.Stderr, myVar1, myVar2, ...)
A third option is to call spew.Sdump to get the formatted output as a string:
str := spew.Sdump(myVar1, myVar2, ...)
Sample Dump Output
See the Dump example for details on the setup of the types and variables being
shown here.
(main.Foo) {
unexportedField: (*main.Bar)(0xf84002e210)({
flag: (main.Flag) flagTwo,
data: (uintptr) <nil>
}),
ExportedField: (map[interface {}]interface {}) (len=1) {
(string) (len=3) "one": (bool) true
}
}
Byte (and uint8) arrays and slices are displayed uniquely like the hexdump -C
command as shown.
([]uint8) (len=32 cap=32) {
00000000 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f 20 |............... |
00000010 21 22 23 24 25 26 27 28 29 2a 2b 2c 2d 2e 2f 30 |!"#$%&'()*+,-./0|
00000020 31 32 |12|
}
Custom Formatter
Spew provides a custom formatter that implements the fmt.Formatter interface
so that it integrates cleanly with standard fmt package printing functions. The
formatter is useful for inline printing of smaller data types similar to the
standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Custom Formatter Usage
The simplest way to make use of the spew custom formatter is to call one of the
convenience functions such as spew.Printf, spew.Println, or spew.Printf. The
functions have syntax you are most likely already familiar with:
spew.Printf("myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Printf("myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
spew.Println(myVar, myVar2)
spew.Fprintf(os.Stderr, "myVar1: %v -- myVar2: %+v", myVar1, myVar2)
spew.Fprintf(os.Stderr, "myVar3: %#v -- myVar4: %#+v", myVar3, myVar4)
See the Index for the full list convenience functions.
Sample Formatter Output
Double pointer to a uint8:
%v: <**>5
%+v: <**>(0xf8400420d0->0xf8400420c8)5
%#v: (**uint8)5
%#+v: (**uint8)(0xf8400420d0->0xf8400420c8)5
Pointer to circular struct with a uint8 field and a pointer to itself:
%v: <*>{1 <*><shown>}
%+v: <*>(0xf84003e260){ui8:1 c:<*>(0xf84003e260)<shown>}
%#v: (*main.circular){ui8:(uint8)1 c:(*main.circular)<shown>}
%#+v: (*main.circular)(0xf84003e260){ui8:(uint8)1 c:(*main.circular)(0xf84003e260)<shown>}
See the Printf example for details on the setup of variables being shown
here.
Errors
Since it is possible for custom Stringer/error interfaces to panic, spew
detects them and handles them internally by printing the panic information
inline with the output. Since spew is intended to provide deep pretty printing
capabilities on structures, it intentionally does not return any errors.

package:
* Pointers are dereferenced and followed
* Circular data structures are detected and handled properly
* Custom Stringer/error interfaces are optionally invoked, including
on unexported types
* Custom types which only implement the Stringer/error interfaces via
a pointer receiver are optionally invoked when passing non-pointer
variables
* Byte arrays and slices are dumped like the hexdump -C command which
includes offsets, byte values in hex, and ASCII output
The configuration options are controlled by an exported package global,
spew.Config. See ConfigState for options documentation.
See Fdump if you would prefer dumping to an arbitrary io.Writer or Sdump to
get the formatted result as a string.

types similar to the standard %v format specifier.
The custom formatter only responds to the %v (most compact), %+v (adds pointer
addresses), %#v (adds types), or %#+v (adds types and pointer addresses) verb
combinations. Any other verbs such as %x and %q will be sent to the the
standard fmt package for formatting. In addition, the custom formatter ignores
the width and precision arguments (however they will still work on the format
specifiers not handled by the custom formatter).
Typically this function shouldn't be called directly. It is much easier to make
use of the custom formatter by calling one of the convenience functions such as
Printf, Println, or Fprintf.

# Keyboard
Simple library to listen for keystrokes from the keyboard
The code is inspired by [termbox-go](https://github.com/nsf/termbox-go) library.
### Installation
Install and update this go package with `go get -u github.com/eiannone/keyboard`
### Usage
Example of getting a single keystroke:
```go
char, _, err := keyboard.GetSingleKey()
if (err != nil) {
panic(err)
}
fmt.Printf("You pressed: %q\r\n", char)
```
Example of getting a series of keystrokes with a blocking `GetKey()` function:
```go
package main
import (
"fmt"
"github.com/eiannone/keyboard"
)
func main() {
if err := keyboard.Open(); err != nil {
panic(err)
}
defer func() {
_ = keyboard.Close()
}()
fmt.Println("Press ESC to quit")
for {
char, key, err := keyboard.GetKey()
if err != nil {
panic(err)
}
fmt.Printf("You pressed: rune %q, key %X\r\n", char, key)
if key == keyboard.KeyEsc {
break
}
}
}
```
Example of getting a series of keystrokes using a channel:
```go
package main
import (
"fmt"
"github.com/eiannone/keyboard"
)
func main() {
keysEvents, err := keyboard.GetKeys(10)
if err != nil {
panic(err)
}
defer func() {
_ = keyboard.Close()
}()
fmt.Println("Press ESC to quit")
for {
event := <-keysEvents
if event.Err != nil {
panic(event.Err)
}
fmt.Printf("You pressed: rune %q, key %X\r\n", event.Rune, event.Key)
if event.Key == keyboard.KeyEsc {
break
}
}
}
```

// Package windows contains an interface to the low-level operating system

// system, set $GOOS and $GOARCH to the desired system. For example, if
// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
// to freebsd and $GOARCH to arm.
//
// The primary use of this package is inside other packages that provide a more
// portable interface to the system, such as "os", "time" and "net". Use
// those packages rather than this one if you can.
//
// For details of the functions and data types in this package consult
// the manuals for the appropriate operating system.

// err represents an operating system error describing the failure and
