Reverse engineered AMC4030 motion controller usbserial protocol. Along with a labwindows/cvi implemented ui frontend.
The sdk from manufacturer's AMC4030.dll's design have several fatal flaws:
- Every call to
COM_API_SetComTypecreates a MFC thread that never terminates. - Multiple calls of
COM_API_SetComTypecauses internal race condition - Protocol itself requires
mfc110u.dllto run. - The first
ch340 usbserial deviceenumerated was used, can be erronous if using ch340 converters for other device, and cannot support multiple device instances. - Binary distribution, not easily portable to new platforms.
Protocol, status monitor and ui frontend separable. Device enumerator included. UI usable as subpanel and runnable as standalone.
More features and fixes may be included later.
Compiles with msvc's compiler both in legacy mode and in c11 mode, cvi's ansi c compiler and with c99 extensions.
Libraries compilable as both static and dynamic. Dynamic library by default (in vs) build with builtin runtime (/MT option)
and does not bloat (only functions like malloc free in stdlib, snprintf in stdio used).
Currently only windows backend implemented for functions that enumerates device or does serial port IO. Help with other backends welcome.
UI frontend requires Labwindows/CVI 2017+ cvirte to compile or run. Other frontend is also easy.
