flexio3_spi_int_b2b_transfer_slave#
Overview#
The flexio_spi_slave_interrupt example shows how to use flexio spi slave driver in interrupt way:
In this example, a flexio simulated slave connect to a flexio simulated spi master.
Supported Boards#
MIMXRT1060-EVKB
Hardware requirements
Mini/micro USB cable
Two MIMXRT1060-EVKB boards
Personal Computer
Board settings
Remove the resistor R347,R348,R349,R351,R363,R364,R365,R366.
To make the example work, connections needed to be as follows:
MASTER connect to SLAVE
Pin Name Board Location Pin Name Board Location
MOSI J33-5 MOSI J33-5
MISO J16-2 MISO J16-2
SCK J33-6 SCK J33-6
PCS0 J16-1 PCS0 J16-1
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.
Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.
Running the demo
You can see the similar message shows following in the terminal if the example runs successfully.
