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]].

===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.

VS project needs updating library and header file paths from project properties (Right click on VScppExample on ''Solution explorer'' pane and go to ''Configuration properties->VC++ Directories'' and change ''Include directories'' and ''Library directories'' to point your location of SimpleMotionV2dll_Release_2 (included in the zip). Also smv.dll must be copied in the same folder than project .exe file (I.e. in Debug or Release folder). | VS project needs updating library and header file paths from project properties (Right click on VScppExample on ''Solution explorer'' pane and go to ''Configuration properties->VC++ Directories'' and change ''Include directories'' and ''Library directories'' to point your location of SimpleMotionV2dll_Release_2 (included in the zip).
