I have been looking at using sd card storage for my f77ish
interpreter. The cards are slow so I have offloaded the io
to a peripheral-based spooler arrangement, ie the peripheral handles the sd interaction and sends/receives bursts of data via spi.
To take a short cut I used an atmega (arduino uno) as the peripheral,
I think the libraries use ChaNs excellent FatFS code.

The data is set as csv files which can be used in excel.
Eg a simple output :





It needs a fair amount of work yet.
Ed - the two lines show signed integer*1, integer*4, 32-bit float, 64 bit float,
an unsigned integer*1 and short text strings saved as an excel csv file in default
formats. Files can be read as data input or written as output, using preset filenames.Edited by chronic 2018-05-02
