I have an application where a 11bit wide adress must be written to digital out ports. I did this by creating the channels with the "DAQmx create channel.vi" and then writing the adress with the "DAQmx write.vi". The problem now is the sequence (mapping) of the output channels. I would like it to be as follows (Dev2 stands for a PCI-6534 card):
adress(0) = Dev2/port3/line0
adress(1) = Dev2/port3/line1
adress(2) = Dev2/port3/line2
adress(3) = Dev2/port3/line3
adress(4) = Dev2/port3/line4
adress(5) = Dev2/port3/line5
adress(6) = Dev2/port3/line6
adress(7) = Dev2/port3/line7
adress(8) = Dev2/port2/line0
adress(9) = Dev2/port2/line1
adress(10) = Dev2/port2/line2
To acomplish that I have defined the "lines" port of the create channel VI with "Dev2/port2/line2:0, Dev2/port3/line7:0". It seems, however, that LabView does not pay any attention on the sequence the channels are defined, the mapping turns out to be always:
adress(0) = Dev2/port2/line0
adress(1) = Dev2/port2/line1
adress(2) = Dev2/port2/line2
adress(3) = Dev2/port3/line0
adress(4) = Dev2/port3/line1
adress(5) = Dev2/port3/line2
adress(6) = Dev2/port3/line3
adress(7) = Dev2/port3/line4
adress(8) = Dev2/port3/line5
adress(9) = Dev2/port3/line6
adress(10) = Dev2/port3/line7
I also tried to create a virtual channel in MAX, but there in cannot define the sequence again and it seems also impossible to combine channels of different ports in the same virtual channel.
Has anybody come across this problem also and can give some tipps. I would appreciate an answer very much.
