I would like to connect several boards to the microcontroller and send data to shift registers placed on the boards. I'm cascading all the shift registers for the data sending from the SPI. But I would like to latch the values individually as the output of the shift register to the board is time controlled and asynchronous to the other registers.
I found this schematic to connect the SPI to the shift register :
With this connection I'm latching the signal directly after the transmission.
Is it possible to just use the clock and the data out of the SPI to connect to the register and choose my own latch signal ? the CS will "exist" in the software but will not be connected to the shift register.
