Stream Object (ADO version 2.5)
The ADO Stream Object is used to read, write, and manage a stream of binary data or text.
A Stream object can be obtained in three ways:
- From a URL pointing to a document, a folder, or a Record object
- By instantiating a Stream object to store data for your application
- By opening the default Stream object associated with a Record object
Syntax
objectname.property
objectname.method
Properties
| Property | Description |
|---|
| CharSet | Sets or returns a value that specifies into which character set the contents
are to be
translated. This property is only used with text Stream objects (type is
adTypeText) |
| EOS | Returns whether the current position is at the end of the
stream or not |
| LineSeparator | Sets or returns the line separator character used in a text Stream
object |
| Mode | Sets or returns the available permissions for modifying
data |
| Position | Sets or returns the current position (in bytes) from the
beginning of a Stream object |
| Size | Returns the size of an open Stream
object |
| State | Returns a value describing if the Stream object is open or
closed |
| Type | Sets or returns the type of data in a Stream object |

Methods
| Method | Description |
|---|
| Cancel | Cancels an execution of an Open call on a Stream object |
| Close | Closes a Stream object |
| CopyTo | Copies a specified number of characters/bytes from one
Stream object into another Stream object |
| Flush | Sends the contents of the Stream buffer to the associated
underlying object |
LoadFromFile
| Loads the contents of a file into a Stream object |
| Open | Opens a Stream object |
| Read | Reads the entire stream or a specified number of bytes from
a binary Stream object |
ReadText
| Reads the entire stream, a line, or a specified number of
characters from a text Stream object |
SaveToFile
| Saves the binary contents of a Stream object to a file |
SetEOS
| Sets the current position to be the end of the stream (EOS) |
| SkipLine | Skips a line when reading a text Stream |
| Write | Writes binary data to a binary Stream object |
| WriteText | Writes character data to a text Stream object |

There are a few problems which it can be used to solve, but for now let us focus on getting an image from that sensor. This sensor is kind of a small camera which has 400 cpi (counts per inch) resolution. And the resulting image consists of 324 = 18 x 18 pixels. The following is from the linked datasheet (p.23): So in order to read a frame I should follow the algorithm: Set the LED to forced awake mode Write anything to the Pixel Data register Read 324 times 6-bit unsigned integer from that register So below is my program. Program Object oriented approach and WriteRegister and ReadRegisters functions (slightly modified) are borrowed from this project by zapmaker. Optical sensor is represented by a class: ADNS2610 class #ifndef ADNS2610_H #define ADNS261...

I managed to convert the above to use Promise and .then() chaining. function getAListOfFiles() return new Promise(function(resolve, reject) fs.readdir(".", function(err, files) if (err)...
