How to use SPI in KL05Z

[northgod]

I'm new to Freescale mcus. I want to control an LCD with the SPI connector. But I don't know how to begin. Can anyone give me a simple guide or a document on where I can find something about this? Thanks a lot.

Thanks for you response. I have read the driver code of spi. What I am

confused about now is the spi0_ss_b pin. Will I connect it to the CS pin of

slave device of leave it unconnected?

Hi, Xuanwu

Pin SPI0_SS_b is slave selection pin, so you need to connect to slave chip selection pin(CS pin).

Hope my reply can help you.
