hi,
I use a similar SD PCB, mine has a single row of pins., connected to a 18F4520, 20mHz xtal.
My set up is 'workable' for my project, but not good enough IMO to publish due to the Oshonsoft Basic limitations.
The uncommented code is attached for your 'look see' of what is required.
The plot is via HC12 transceiver, for ref only.
