does this driver support flying scan? #2

Neither the C300 driver nor the LC400 driver currently support fly-scanning (profile moves in asyn motor terminology).

My understanding is that the C300 controller doesn't have the capability to do fly scans, but the LC400 does, using the wavetable feature, which is currently used for point-to-point moves.

thanks for the response.

Would it be possible to use LC400's Digital IO to trigger flying scan? It generates TTL "output on position" signal at specified motor positions (start, interval, number of pulses).

I'm just trying to understand if it's not implemented by EPICS driver yet or if it's not feasible.

Thanks.

Regards.

My understanding is that it is possible, but no one has implemented it yet.

Hi @LeeYangLBLBCS, it's certainly doable with the LC400 but it is not implemented in the current EPICS driver.
