Is there a limit to how many slaves you can control with a Arduino board using the SPI bus as long as you do not run out of pins?
Uno, for example, has 14 digital I/Os. So theoretically, I could have 11 slaves if I wanted to since MISO, MOSI and SCLK will be shared and there would be 11 different CS pins. I was wondering if anyone would run into any practical problems long before controlling 11 slaves. ( Although I will not use MISO )
I plan on controlling six 12 bit DACs for a project using UNO using the SPI bus. Is there something I need to be aware of?
