Title: How many SPI devices can be connected?
Post by: awallin on May 14, 2013, 10:12:25 PM

I noticed the UEXT connector has one chip-select line.

Does that mean the maximum number of SPI-devices is two?

I'd like to use an olinuxino+touch-screen as the UI/Controller for various projects, but these will probably have minimum three, and possibly up to eight, SPI ADCs or SPI DACs  that I want to talk to.

Sorry for my ignorance  :P
