I would love an update to the signal processing VI's contained in NI_MAPro.lvlib to support waveforms with a SGL Y-value representation. The library is locked and most VI's call dll's that are not able to be modified anyways (by me that is, I am not all that strong in traditional text based languages). It would be nice to also support SGL waveforms within the .llb's contained in vi.lib/measure; although these are mostly unlocked and able to be modified.
Working with a cRIO, the FPGA to host DMA channels encourage the use of SGL data type so I went with it and kept it as SGL throughout my application. For some functions I turn my SGL array into a waveform with SGL Y-value representation. I was disappointed to learn that most of the signal processing waveform tools contained in NI_MAPro.lvlib do not support the SGL Y-values.
The predessesor application was done on the usb cDAQ line that i was using DBL representation Y-values. I want to re-use a lot of code and was hoping the waveform signal processing VI's would accept SGL Y-values. For now I am stuck converting my data type for the sole purpose of re-using code; at 50kHz on 36 channels this can become a performance issue.
