Global

The objects are available in a global scope. The objects in the Global are not need to have a require function call before using it.

Object: global

require(module_name)

• module_name <string>Module Name which would be used in the script.
• Returns: <any> Return exports object of the loaded module.

var graphics = require('graphics'); // Load a builtin module

print([...data])

• ...data <any>Data which is shown in the console.

Print out data to the console. The main difference from console.log() is that it do not print a carriage return and a new line character (\r\n) in the end.

// print out "100 string value true 1,2,3"
var number = 100;
var result = true;
var arr = [1, 2, 3];
print(number, 'string value', result, arr);

seed(seed)

• seed <number> A seed number to initialize.

Initializes the pseudo-random number generator. When you use Math.random(), it generate always the same random sequence. If you want to generate different random number sequence, you need to provide different seed number.

// Seeding by millisecond time
seed(millis());

// Seeding by analog input
seed(analogRead(26) * 10000); // GPIO26 = ADC0

btoa(data)

• data <Uint8Array|string> Binary data to encode.
• Returns: <string> Base64 encoded string.

Returns a base64 encoded string from binary data.

atob(encodedData)

• encodedData <string> Base64 encoded string data.
• Returns: <Uint8Array> Decoded binary data.

Returns a decoded binary data from a base64 encoded string.

encodeURIComponent

• data <string> Data to encode.
• Returns: <string> Encoded data.

Encodes URI (Uniform Resource Identifier) component using percent-encoding. This function escapes all characters excepts A-Z a-z 0-9 - _ . ! ~ * ' ( ).

decodeURIComponent

• data <string> Data to decode.
• Returns: <string> Decoded data.

Decodes URI (Uniform Resource Identifier) component using percent-encoding.

LOW

• <number> = 0

HIGH

• <number> = 1

INPUT

• <number> = 0

OUTPUT

• <number> = 1

INPUT_PULLUP

• <number> = 2

INPUT_PULLDOWN

• <number> = 3

LOW_LEVEL

• <number> = 1

HIGH_LEVEL

• <number> = 2

FALLING

• <number> = 4

RISING

• <number> = 8

CHANGE

• <number> = 12
