Hardware requirements

Hardware requirements#

  • Mini USB cable

  • FRDM-MCXC242 board

  • Personal Computer

Board settings#

SPI one board:

  • Transfer data from instance0 to instance 1 of SPI interface, SPI0 pins are connected with SPI1 pins of board

INSTANCE0        CONNECTS TO         INSTANCE1
Pin Name   Board Location     Pin Name  Board Location
MOSI       J2 pin 8           MOSI      J2 pin 18
MISO       J2 pin 10          MISO      J2 pin 20
SCK        J2 pin 12          SCK       J1 pin 11
PCS0       J2 pin 6           PCS0      J1 pin 9

Prepare the Demo#

  1. Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.

  2. Open a serial terminal on PC for OpenSDA serial device with these settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Reset the SoC and run the project.

Running the demo#

When the demo runs successfully, the log would be seen on the OpenSDA terminal like:

SPI one board interrupt example started!

SPI transfer finished!
