Help req wih shift register

[Anonymous]

 I was trying to use the shift register of PSOC creator 1.0 and I wanted to know what is the easiest possible way of knowing by hardware when the parallel value loaded in the shift register has been shifted out completely.

   

Thank You

Hi antimatter,

   

I would suggest to count the number of bits with a counter :reset with Load shift, count up with shift-clock,compare with bit-count.

   

Have fun

You can use SPI if you only need to shift data out with a shift clock.

Hi antimatter,

       

You can use counter component to keep track of the number of clocks that has elapsed (which is equal to the number of bits shifted). Interrupt on terminal count can be used as a trigger to load a new value into the Shift Register.
