Hi everyone,
I'm triying to use the SPI with kinetis K20, I want to use it as a Slave and other device will be a Master, this device will generate a CLK signal and it will send de data. The CLK is 2 MHz.
I have done the configuration the image shows. I'm not able to receive any data, I don't know why, probably I'm doing something wrong, its the first time I work with kinetis. If some one can help me....
Thank you in advance.

Hi,
Have the data been ready in the K20 SPI's data register before external master launch the reading operation? I have some customers met such problem due to this, please kindly check it in your application code.
Hope that helps,

Hi,
I have make a demo on TWR-K40X256 boards with [SPISlave_LDD] & [SPIMaster_LDD], which could use TWR-K40X256 J4 jumper.
J4-1 PTA16 SPI0_SOUT (ALT2)
J4-4 PTA15 SPI0_SCK (ALT2)
J4-6 PTA14 SPI0_PCS0 (ALT2)
J4-7 PTA17 SPI0_SIN (ALT2)
J4-8 GND
I also attached my test project for your reference.
Both SPI slave and master can receive the data.
Wish it helps.
