Writing to 9802 with CRio 9074

[Dhasa]

Hi Everyone,

I am trying to write to SD cards on a 9802 module using a CRio 9074. I notice the files are always BIN files which I cannot make sense of. Do I have options to save the files being written to other formats or do I have to write another FPGA VI to read the written files? If this is the case then I cannot just retrieve the SD cards and read them on any computer port - I have to read them from the 9802 itself?

Thanks!

Hi Dhasa,

you can read the bin files on every pc, but you have to write a program which can read the file. Your data in the files depends on the type you write to the file (U8, U16 or U32). Every number you write to the file will be added to the existing data.

Hi Mike,

 Do you have an example of a program that can read bin files on a PC? Is it essentially a FPGA or Host vi running on the computer? 

Thanks!

I just spotted the "read from binary file" function. I guess this is what you meant, Mike.  I am going to give this a shot and then get back to the message board. Thanks a lot.

Hello,

I think the following discussion forum post and "Bassett Hounds" response will go along way to explain how to write to SD cards in LabVIEW FPGA. Hope this helps.

Hi Dhasa,

yes that's the function i meant. You don't need FPGA functions to read the data.
