cmsis_spi_int_b2b_transfer_slave#
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.

Running the demo
This demo is an external flash plain load demo, ROM will copy image in external flash to SRAMX to run:
Build the demo to generate a bin file. Note: If need to generate bin file using MCUXpresso IDE, below steps need to be followed: Set in example Properties->C/C++ Build->Settings->Build steps->Post-build steps->Edit enbable arm-none-eabi-objcopy -v -O binary “&{BuildArtifactFileName}” “&{BuildArtifactFileBaseName}.bin”
This plainload example linked the vector table to 0x00000000, but program to external flash 0x10000000.
Program the bin file to external on board flash via SEGGER J-FLASH Lite(V6.22 or higher):
a. Open SEGGER J-FLASH Lite, select device LPC54S018.
b. Click the ‘Erase Chip’ to erase the extrenal flash.(if can not success, press SW4 button and reset the board, and try to erase again)
c. Select the bin data file, set the ‘.bin/Erase Start’ address to 0x10000000, then click ‘Program Device’ Note: Please use above way to program the binary file built by armgcc tool chain to external flash. For IAR, KEIL, MCUXpresso IDE, you can use the IDE tool to program the external flash.

Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the demo.
Running the demo
When the demo runs successfully, the log would be seen on the terminal like:
SPI CMSIS driver board to board interrupt example.
Slave example is running...
