HI All,

I am trying to modify the default spi example code. Here i want to toggle the SS line for every bytes transfer , Please suggest how do i can achieve this ?

If i want use GPIO for this where should i add?

Hi,

The SS pin is set at the start of a transfer when using the nrfx SPIM driver. The easiest witch requires no modifications of the driver would be to partition your data that you transfer into several chunks of bytes. The SS pin would therefore toggle between each call to nrf_drv_spi_transfer().

Yes Jared .. current  my implementation is like that only but i see 5usec delay between the CS LOW and the start of clock

5 µs is within what's expected.
