Need help with SPI and logic analyzer for KE06Z SDK.

[tcwong]

Hello,

I downloaded the SDK for the KE06Z and found the sample code spi_interrupt_b2b_master.c. How would you edit this code to send the 8 bits of data you would want to send (i.e. 00100001) to be viewed by a logic analyzer? Thank you in advance.

Hi Tyler Wong,

SPI_WriteData can be used to achieve it.

You need to modify the spi_interrupt_b2b_master project.

The pins of logic analyzer need to connect with KE06 pins.

Best Regards,

Robin

Hello Robin,

Thanks for the reply! So just to clarify, if I wanted to write 00100001, or 0x21, for example the function would look like SPI_WriteData(EXAMPLE_SPI_MASTER, 0x21)? Is this correct?

Best,

Hi Tyler Wong,

Yes. After modify the codes, the spi_interrupt_b2b_master project will send 0x21.

You can have a try.

Best Regards,

Hello Robin,

So I replaced the same line you did but my MOSI is just outputting 0xFF instead of 0x21. Do you know the reason for this? Below is what my program is outputting as a reference. Thanks in advance.

Best,

Tyler

Whoops I just realized I was reading the wrong line. Thank you
