Overview
========
CMSIS-Driver defines generic peripheral driver interfaces for middleware making it reusable across a wide
range of supported microcontroller devices. The API connects microcontroller peripherals with middleware
that implements for example communication stacks, file systems, or graphic user interfaces.
More information and usage method please refer to http://www.keil.com/pack/doc/cmsis/Driver/html/index.html.
The cmsis_spi_interrupt_b2b_transfer_slave example shows how to use CMSIS spi driver as master to do board to board transfer
with interrupt:
In this example, one spi instance as master and another spi instance on the other board as slave. Master sends a
piece of data to slave, and receive a piece of data from slave. This example checks if the data received from
slave is correct.

Prepare the Demo
================
Note: MCUXpresso IDE project default debug console is semihost
1. Connect a micro USB cable between the PC host and the LPC-Link USB port (P6) on the board.
2. Open a serial terminal on PC for JLink 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. Either press the reset button on your board or launch the debugger in your IDE to begin running
the demo.
Running the demo
================
The following message shows in the terminal if the example runs successfully.
