SM V2 is a complete redesign of the original [[SimpleMotion library]]. The main goals have been increasing flexibility and performance while still preserving the simplicity of the [[Wikipedia:Application programming interface|API]]. | SM V2 is a complete redesign of the original [[SimpleMotion library]].

SM V2 is based on RS485 physical interface yielding ability to link multiple device nodes into a single data link. Each device in the bus has unique address making it possible to target the commands to specific axis. | SM V2 is based on RS485 physical interface yielding ability to link multiple device nodes into a single data link.

===Buffered commands=== | ===Buffered commands=== | ||
| − | In addition to instantly executed commands, SM V2 supports buffered commands meaning that commands may sent as chunks of multiple commands that are later interpreted by devices at predefined pace. This makes it possible to implement multiaxis synchronous interpolation without requiring a real time [[controller]]. Ring buffer implementation allows running infinite length sequences of commands | + | In addition to instantly executed commands, SM V2 supports buffered commands meaning that commands may sent as chunks of multiple commands that are later interpreted by devices at predefined pace.

===Performance=== | ===Performance=== | ||
Due to relatively high bitrate of RS485 bus and byte-efficient serial protocol, SM V2 performs very well in multiaxis real time & buffered applications. At default bit rate at least 6 axis continuously interpolated motion is possible. | Due to relatively high bitrate of RS485 bus and byte-efficient serial protocol, SM V2 performs very well in multiaxis real time & buffered applications.
