Issue with SPI Communication on LPCXpresso Board

Hello everyone,
I'm working on an LPCXpresso board and facing difficulties with SPI communication between the microcontroller and an external sensor. Despite configuring the SPI settings correctly (clock polarity, phase, and baud rate), I am experiencing inconsistent data transmission and occasional timeouts.
Has anyone encountered similar issues? Could there be additional settings or debugging techniques I should consider? Any guidance or example code would be greatly appreciated!
Thanks in advance! 

Paul

Hi Paul81Harris,

What's your chip part number?

Which demo board do you work with?

Thanks,

Jun Zhang
