I am driving a RGB led strip (ldp6806) with SPI.
Since the led strip does not have a chip select input, I would like to know how I can drive this strip with another SPI item connected to the Pi (like an arduino, another strip, or anything else...), by adding a "chip select"-like circuit between the RPi and the led strip (or any other SPI slave that does not have a chip select line).
Any idea how can I start ? Maybe I could build a simple logic gates circuit to have clock and MOSI flat when chip is not selected?
