byte-cast
byte-cast is a MaxMSP utility object for casting a list of bytes to other data formats. Useful when interacting with Arduino using the serial object.
Install
Unzip the package folder into you ~/Documents/Max 8/Packages directory.
Usage
This release covers all the standard data types:
| Format | Data Type |
|---|---|
| i | 32-bit int |
| h | 16-bit int |
| f | 32-bit float |
| s | ASCII string (greedy) |
Modifiers:
u: unsigned (iandhonly)>: Big endian (append)<: Little endian (append)
Endianness Toggle:
0 or 1 in the right inlet will flip the endianness.
Behaviour
The string format will greedily use up the entire byte list and attempt to translate to ASCII characters until the end. Bytes outside of the symbol range 32 - 126 will be replaced with a ' ' character.
The number formats will send out a list for as many complete numbers that are available. Any incomplete numbers will be ignored.
e.g. if you send 7-bytes when in float format, a single number will be output. If you send 9-bytes, 2 numbers will be output.
