## Classes
|
|
|
|
### class array.array(typecode, [iterable])
|
|
|
|
Create array with elements of given type. Initial contents of the array are given by an iterable. If it is not provided, an empty array is created. Supported format codes:
|
|
* `b`: signed char, 1 byte
|
|
* `B`: unsigned char, 1 byte
|
|
* `h`: signed short, 2 bytes
|
|
* `H`: unsigned short, 2 bytes
|
|
* `i`: signed int, 2 bytes
|
|
* `I`: unsigned int, 2 bytes
|
|
* `l`: signed long, 4 bytes
|
|
* `L`: unsigned long, 4 bytes
|
|
* `q`: signed long long, 8 bytes
|
|
* `Q`: unsigned long long, 8 bytes
|
|
* `f`: foat, 4 bytes
|
|
* `d`: double, 8 bytes
|
|
|
|
Adapting the typecode to the array-type you want to create can save a lot of space on the microcontroller
