2.4.5.7. - Miscellaneous

reconfig

Reconfigures the hardware. This command obtains any modified configuration information, including hardware devices and types, CAMAC slot assignments and motor parameters and settings, from the config and settings files. The sequence of events is as follows:

First, spec waits for all asynchronous activity (moving and counting) to finish. It then does a sync of the motor controller registers, comparing them with the internal program positions. Next, all open devices are closed. The config file is then read to obtain the configuration information, and the program opens and possibly does hardware presence tests on the selected devices. Finally, the internal program motor positions are updated from the settings file and then resynchronized with the motor hardware.

set_sim(how)

If how is 0, simulate mode is turned off. If how is 1 (or positive), simulate mode is turned on. In either case the program waits for moving and counting to finish before changing the mode, and the function returns the previous mode (0 or 1). If how is -1 (or negative) the function returns the current value of simulation mode without changing it. Whenever simulation mode is turned off, the motor settings file is reread to restore the motor positions. Simulation mode cannot be turned off if spec was invoked with the -s flag.

wait()

Waits for all asynchronous activity to complete. Returns true .

wait(flag)

If flag has bit one set (1), waits for moving to finish. If flag has bit two set (2), waits for counting to finish. If flag has bit three set (4), waits for other data acquisition (multi-channel scaling, for example) to finish. If flag has bit five set (32), the function returns true if any of the activities flagged by the first three bits are active, otherwise it returns false . Thus wait(35) (or wait(0x23)) returns true if either counting or moving is active.

stop()

Stops all asynchronous activity. Returns true .

stop(flag)

If flag has bit one set (1), stops all motors that are moving. If flag has bit two set (2), stops the timer, counters and any other data acquisition (multi-channel scaling, for example).
