NRF52 FDD SDK15 questions

[Andrew_Engineer]

Hello,

we are trying to use FDS with NRF52 and using SDK15 SD132 v6.0, and have few questions:

1. IF there is function to erase all records and files in FDS?

2. What is absolute max space can be reserved for FDS?

3. In SDK_config.h We specify 18 pages and 2048 virtual page size but when we called  fds_stat(...) we are getting only 12 pages why

4. what is maximum data throughput to the FDS; ie we are sampling analog signal through I2S @ 16KHZ 2 channels 16 bit 256 samples. and looks like flash storage cant keep up with this rate. Can you please advise what's max data rate?

Thank you,

Andrew

Hi,

You can find every function in the FDS API documented here.

1. fds_file_delete() deletes all records in a file. 
2.  See this thread on how the memory is laid out.
3. You probably don't have any more space available.
4. Function calls in FDS are asynchronous which mean that they are only queued after the function call and will be performed some unspecified time after the call. 

regards
