I am using KDS sample project dspi_blocking_example_master_frdmk22f provided with Kinetis SDK 1.2.0 to initiate SPI transfer from FRDM K22F board. The sample project should configure the microcontroller as master and configure SPI0 interface.
If I connect an oscilloscope to pins PTC4 (PCS0), PTC5 (SCK), PTC6 (MISO), PTC7 (MOSI), I don't see any output from these pins. I also tried using AARDVARK SPI adapter and I am unable to receive any data on that either.
Since it's a sample project, I thought it should just work fine. Can you please suggest me if I am doing anything wrong?
