Sharing SPI bus with APA102 & n other peripherals ( faking an 'APA102 CS' pin )

Hi !

To increase the number of available pins on the Espruino Wifi ofr a current project, I wish to share the I2C & SPI bus for several peripherals:

On the I2C side:

• OLED screen ( addr 0x3C )
  
• Color sensor ( addr 0x29 )
  On the SPI side:
  
• APA102
  
• SDCARD
  
  

I had a quick thnk on 'may-be solutions', but I'd be glad receiving further advices before not knowingly messing around

The following drawing is for the SPI side of things, but I wonder if fiddling with the I2C CLK would lead to same behavior ?

Thanks in advance :)
