Please, help me.

I'm resarching for SPI daisy chain.

MAXIM uses this way,

http://www.maxim-ic.com/app-notes/index.mvp/id/3947

They shift the signal each devices.

I'm looking for other way to connection.

Does anyone know SPI daisy chain?

I try to make "pile up SPI modules".

Maxim's IC is useless for this system, because the bus lines are all parallel.

Like this, http://wizard.nestegg.jp/what.html#2b

I used 1 wire pulse signals.

But, It is not good for timer interrupt system.

I found other ways with PIC.

However, I want to use dedicated IC for SPI daisy chain, if it exists.

Thank you for sending many advices on Facebook. I found it! But, the setting the channels is few. I'll try to make it.
