communicating with the arm

[tau at wayne]

Hi ,

I am working on a project and I am using arm micro, to do the data processing and give the output through SPI. The problem though is that I have to input a few values which now include 300 numbers. Puting tham in arm memory by using a keypad would be a pain in the nec, so I was thinking of reading the values fromexcel file and use lovely labview to send them through usb/serial to my micro.

My question is, how can I program the arm to save the incoming data somewhere and read them later on for processing? I mean how can i do that with embedded module ?

Thank you

Hi tau at wayne,

There is File I/O functionality in LabVIEW for ARM, but it can depend on the hardware that is associated with the processor. Can you elaborate a little further on the evaluation board or hardware you are using with your ARM processor? Also, what version of LabVIEW are you working with?

Myboard is stellaris EKS- LM3S9B90. Labview 2009.

I plan to use Labview to send user inputs through to the board, either through serial or usb and program the rest in C, but I dont know how to manage it. By the way, the board has no serial port, I was thinking of making a few pins as serial input. Could you give a suggestion on how to implement it?

Thank you Aaron

Hi tau at wayne,

What sort of transfer buses do you have available to you? USB?

Yes I do have USB in the board, but I was hoping to do it the easy way.

I am still open to the USB idea. I am not sure if it is the USB type that labview needs though.
