Hi,
My slave device has only one bidirectional data line. Now I want to configure the SPI in the half-duplex mode. And I noticed that the reference manual gave an descripiton of 1 clock and 1 bidirectional data wire.
I want to ask if ST has peripheral libraraies for this or provide routine demo.
Thanks a lot!

Unless the spi has been improved, avoid this mode. Use 4 wire spi, short miso and mosi externally, and turn mosi as input when needed. Once this works, nothing prevents you from trying above feature. Step by step.
