Board settings

To make the example work, connections needed to be as follows:

MASTER(FlexIO SPI)          connect to      SLAVE(FlexIO SPI)
Pin Name   Board Location                   Pin Name    Board Location
SOUT       J1 pin 13                        SIN         J1 pin 13
SIN        J1 pin 7                         SOUT        J1 pin 7
SCK        J1 pin 15                        SCK         J1 pin 15
PCS0       J1 pin 5                         PCS0        J1 pin 5

Prepare the Demo

1. Connect a USB cable between the host PC and the EVK board J14.

2. Open a serial terminal with the following settings:

   • 115200 baud rate

   • 8 data bits

   • No parity

   • One stop bit

   • No flow control

3. Download the program to the target board.

4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
