Two threads are better than one
QuickSilver Controls has now added Multi-Thread capacity to its line of NEMA 17 and 23-frame motor servo controllers/drivers. Now, two programs can run at the same time, in the same controller. One thread can run motion-oriented programs, and the other can be dedicated to I/O processing. It offers 240-µsec instruction execute time with both threads running. The 1MB CANOpen, 230KB serial channels and 8KHz servo loop all execute as normal. Information passes between threads via shared data registers. Each thread can change or shut down the other, and there are advanced debugging features available such as single-step and breakpoint operations on one thread while the other is running normally.
