Hi all,
I have a question , we developped a complete application which is able to read, write AI, AO, DI , DO PWM, CAN .... all of these are completly parametrable ... now, in order to improve the performances of some modules we are interrested in replacing some DAQmx modules with FPGA.
The problem ius the following : with DAQmx, if you use for example a PXI 6254, you can parameter this card to read / write DI/DO/AI... All this stuff can be done in programmatically ... However in FPGA , you can not change the function of the card... the only thing you can do is to load a different bitfile ... So if my understandf is good if i use a 7831R i have to create the programm to read 4 AI , another to read 8 AI and so on ... it's not possible to configure the board programatically .... I can understand that ... But what i don't understand is: when i use the open function in the host vi why is it not possible to specify the bitfile to transfert ??? If that could be possible i could create a library of bitfiles which can be downloaded in the card depending the need of the user ...
I don't know if everything is clear , but i think i'm not the first one who face this problem .... euhh i hope .. LOL !
