flexcomm_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.

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. When the demo runs successfully, the log would be seen on the terminal like:
SPI one board interrupt example started!
SPI transfer finished!
