Hello!
In an SPI Daisy Chain connection, there is typically no fixed limit on the number of devices. However, the number of devices you can use depends on your specific application. When n devices are daisy-chained, n SPI 16-bit word cycles must be executed to program all devices. Each device features a 16-bit shift register (equivalent to 2 bytes), allowing devices with data sizes in multiples of 8 bits to share the same daisy chain.
Since data shifts from one device to the next until it reaches the last one in the chain, you should consider that there is a latency of one command cycle from DIN to DOUT for each device in the chain.
Hope this helps!
