Hello All,
If anyone has an answer to my question below please feel free to respond.
When two devices are Cascaded to a uC via SPI is it possible to send seperate commands to each device without having to control CS(SS) on each device.
I am a little confused with the Cascading description. does the word length increase to 16 bits, with the first 8 bits being sent going to the second device(as it would get shifted out of first device) and then the second 8 bits then going to the first device in the chain?
Or would the first 8 bits get shifted in to both devices and then when second 8 bits is sent it then gets shifted into both devises? (this not what i want).
If this is the case then i will have to enable seperate control of CS on each device.
Any help appreciated
