LPC54618 SPI Interrupt example code not work

chengyohuang — Wed, 20 Sep 2017 13:01:32 GMT

I downloaded the SPI interrupt example code of SDK_2.2_LPCXpresso54618 to my LPC54618 CAN FD Kit and i did not make any changes code，but SPI slave always received error.I connects to J14-1.2.3.4

and i read the spi interrupt "readme.txt" file，Is the example SPI Master PIN correct?because i connects to J9-PIN10.11.12.13 have SPI Master Data(0~63).But connects to J9-PIN9.11.13.15 have nothing

This is my way of connecting the entity

What can I do to make the SPI interrupt example code successful?@#

Hi Cheng yo huang,

Please remove the CAN FD board, check the LPCXpresso 54618 board version, what the version you are using?

Have a great day,
Kerry

Hi Cheng yo huang,

This code is working in revB, but LPCXpress54618 rev C need to take care JS34, JS35, you need to modify the board connect, you need solder it in the correct position.

Besides, you need to connect JP6.

Have a great day,
