Hello

I am prototyping an audio recording/playback project. I am planning to control an SD card and two cascaded SIPO shift registers both independantly with a single SPI from an Atmega 32. To avoid conflicts I want to implement some sort of switch between the two.
Do I need something like this?
I was initially planning to use AND gates but since I am going to need to read from the SD card aswell AND gates are out of the question since they are one-way only.
The sd card is for recording the audio and the shift registers are going to be outputs to a "hand made" DAC accepting parralel inputs.

 

Oh nevermind... I just noticed there is a CS pin on the SD card breakoutboard
I feel slightly embarrassed for making this thread lol

 

Meh, don't worry about it. I was going to mention something about the chip select, but figured you wouldn't have missed that!

Sometimes it takes asking a question with an obvious answer for the answer to become obvious.

 

Yeah I haven't worked with SPI for a long time so I completely forgot that it inherently supports multiple slaves on a single bus
