Re: write data to the sd card or usb
Hi,
yes it is possible to write data to a file on SD card. Data can be of a type vector.
If you are trying to save acquiered data, you can read more over here.
Please post more details on what you are trying to do, so we can give you a more precise answer.

Re: write data to the sd card or usb
How often are you sending data and receiving data?
The limiting factor here is the speed of the SD card, then there is also a detail on how RP stores data.
The process is that ADC data is stored in the FPGA memory which is a 16k samples block, then this data can be read and stored. However during the reading step no new data is acquired.

I think that this speed should be achievable with out any problems with an SD card.
