Tnak you very much for your answer, but if i want to use the function LPSPI_DRV_MasterTransferBlocking. i have to use like LPSPI_DRV_MasterTransferBlocking(SEND,NULL, &buf, 1,100)?

According to the SDK documentation, the function with a NULL parameter will send bytes with 0 value.

I don't see any option to configure a half-duplex mode in the PEX of the SDK driver.

However, the MOSI signal of the LPSPI module does not have to be routed to any pin if you use a 3-wire bus.

Daniel
