spi_interrupt_b2b_slave

spi_interrupt_b2b_slave#

Overview#

The spi_interrupt_b2b_slave example shows how to use spi functional API to do interrupt transfer as a slave:

In this example, the spi instance as slave. Slave receives data froma master and send a peiece of data to master, and check if the data slave received is correct. This example needs to work with spi_interrupt_b2b_master example.

Supported Boards#

FRDM-K32L2B
Hardware requirements
  • Mini USB cable

  • Two FRDM-K32L2B boards

  • Personal Computer

Board settings

SPI board to board: Transfers data through SPI interface. SPI0 pins of the master board are connected to the SPI1 pins of the slave board.

##### 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 board to board interrupt slave example started!

SPI transfer finished!
