SPI

Hello,

I have one program for SPI. It uses Xspips driver for SCLK and transfers bits over MOSI pin.

By default, My SCLK is low when inactive. Also, it is on trailing edge for MOSI. Is there a way that I can change it so SCLK will be High when Inactive and rising edge?

Thanks in advance.

Hi Vatsalnaik,
I suppose it is possible to activate two slaves at the same time, however I would not advise doing so. If both slaves try to talk to the same MISO line your result will be a garbled unreadable output. That is unless you plan on daisy chaining them together.
