How can I manage 2 SPI slaves (N°1 STPM32 and N°1 STPM34) with SPI chip select with STM32 Standard Peripheral Libraries with only a master micro ST STM32F100x8 ?

[LuxMux]

I need to use STM32 Standard Peripheral Libraries because I already use it for other Peripheral on the same board. I fine some example of stpm_metrology using HAL library, but I cannot use it!

Do you have some example of SPI communication with STPM3X with SPL libraries?

Many thanks in advance
