NI PCI 6220 ADC board
in [Matlab]

From: Ben Chiel on 12 Apr 2010 17:00 I have attempted to use the solution posted here, but unfortunately I've been unable to get any signal from the simulink block. I've tried changing the block settings to match the non-xPC 6220 A/D board, changing the voltage input range, using differential signal mode, adding all 16 channels and looked at all of them (though the 6220 A/D itself has only 7 channels), but I don't get any signal from any of them. The non-xPC block works perfectly. I noticed that the S-function the blocks point to is not the same, but the working non-xPC block does not seem to point to a block matlab can find, so I can't change the xPC block to point to it. Ideas?

From: Gordon Weast on 13 Apr 2010 09:23 Ben, I'm not sure I understand what you're trying to do here. Your mention of 'non-xPC' makes me suspect that you're trying to get the block to work in simulation on the host. That won't work with the xPC Target blocks. The xPC Target driver goes directly to the hardware to read and write registers. If you need this on the host, you need a different solution that calls the NIDAQ library. The Data Acquisition Toolbox includes blocks for simulation on the host for the 6220. Am I understanding what you're trying to do?
