How to test SPI interface between two boards using LPC55S69 EVK

sushmasan — Wed, 04 Sep 2024 18:00:27 GMT

Hello Team,

I am using LPC55S69 EVK, just wanted to check, how can I test SPI interface between two different boards, treating one as master and other as slave?

Please provide me few pointers.

Regards,
San

Hello @sushmasan

What's your other board? For LPC55s69 side, there is SPI master/slave demo under SDK. You can use it. Download SDK from: https://mcuxpresso.nxp.com/en/select

Hello @Alice_Yang ,

Sorry, I missed to add more details in my previous question.

Still I am figuring out about the other hardware. Meanwhile I am trying to test SPI, I2C interfaces.

Can I able to use SPI, I2C communication between two different LPC55S69 EVK's? How can I do that?

San

Hello @sushmasan

Yes, you can. Just follow the readme under SDK example to connect hardware and run code.

For example SPI_interrupt demo. Hardware connection as below:

Hi @Alice_Yang ,

Thank you so much. It is really helpful. I didn't realize that there is a readme file. After checking the directory structure, I saw there is a doc folder which contained the readme file.
