Hi Bernd, Yes, I think the current implementation is fixed to allow only 1 CS per RP2040 SPI.
That is not ideal (read: "incorrect"). It is possible to have the rp2040_spi.c as a common boards file, but the CS should be extended, i.e.: #if defined(LCDxyz) || defined(LCDwku) ... rp2040_gpio_put(BOARD_RP2040_SPI0_DISPLAY_CS, !selected); #endif #if defined(AUDIOCODECtqj) || defined(AUDIOCODECcnp) ... rp2040_gpio_put(BOARD_RP2040_SPI0_AUDIO_CS, !selected); #endif etc... This way the common rp2040_spi.c file could support many more devices than current implementation.
