S32K 3line SPI

hi:

I use the S32K144，RTM4.01 IDES32DS3.5，but the SDK library without a three-wire SPI Demo, can you provide a three-wire SPi demo?

Hi @ChenPeng3

The functions implemented at the SDK for LPSPI do not have "native support" for 3-wire. So it required to make some changes to support half duplex mode. Also, check the following thread. It has information related to the topic that might be useful.

S32K 3-Wire SPI Drivers

Additionally, included with the Real-Time Drivers for S32K1 examples of SPI half duplex transfer are provided.

hi@VaneB

Thanks for the reply, RTM 4.01 needs to modify the underlying driver library to implement this feature.
