I need 3-wire SPI configuration for S32K142 processor and I use S32 Design Studio v2.2
Is the current SDK(RTM 3.0.0) valid for half duplex communication?
Could I use LPSPI component on processor expert for half duplex SPI?
Could you share me sample code or any document about this topic?
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.
Included on the RTDs comes an example of SPI half duplex transfer. I suggest you take a look at this software supported by S32DS v3.4.
