spi_interrupt#
Overview#
The spi_interrupt example shows how to use spi functional API to do interrupt transfer:
In this example, one spi instance as master and another spi instance as slave. Master sends a piece of data to slave, and check if the data slave received is correct.
Supported Boards#
FRDM-K32L2B
Hardware requirements
Mini USB cable
FRDM-K32L2B 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
MISO J1 pin 11 MISO J2 pin 10
MOSI J1 pin 9 MOSI J2 pin 8
SCK J1 pin 15 SCK J2 pin 12
PCS0 J1 pin 7 PCS0 J2 pin 6
Prepare the Demo
Connect a mini USB cable between the PC host and the OpenSDA USB port on the board.
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
Download the program to the target board.
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!
