Hi Members,

I want to know if TRF79XX( TRF796X+ TRF7970A) can share SPI bus with other device directly. Of course, The

CS (SS) pin is not shared.

Hi SeaFesse

I am also sharing the SPI bus with another device. The Clock speed is set to 2MHz. The another device and the TRF is working fine.

Surely the SS is different for different devices

Although it is not technically recommended, I am also sharing the three SPI lines with no problems.
