All,
I have just delivered a software calibration feature for the NI M family of
acquisition cards
"pci-6220", "pci-6221", "pci-6221_37pin", "pci-6224", "pci-6225",
"pci-6229", "pci-6250", "pci-6251", "pci-6254", "pci-6259", "pcie-6259",
"pci-6280", "pci-6281", "pxi-6281", "pci-6284", "pci-6289"
Usage of the calibration tool requires:
1. to use the analogy_calibrate utility to generate a calibration file for your
board.
$ analogy_calibrate --device /dev/analogy0 --output /path/calib.bin
2. use the library functions to parse and apply the calibration file to samples
(read
from hardware) or values (to be written to hardware)
An example on usage is in the utility function "insn_read" now accepting a
calibration file as input.
This feature will be available for xenomai-3 only and there are no plans to
backport
it to xenomai-2.
For the time being you can find the relevant commits in the tree/branch below
