I am trying to write C test code for SPI peripheral module for Pulpissimo.I have gone through the test case mentioned in pulp-rt examples.
[https://github.com/pulp-platform/pulp-rt-examples/tree/master/periph/spim][1]
But I understand that the above code need the support of an external board. I have no board available with me. Is there any way to write test case in C for SPI?
