I am trying to construct a pulsing circuit using a 555 timer. I want to trigger it from a 51-bit stream. I am feeding the bit stream into a shift register with the idea of clocking it in serially and then feeding it into a load of latches. Which also needs clocking. There is a particular bit in the stream I want to use as my trigger, which at some point will have a transition, so it needs to be continually monitored by the timer. The timer needs to O/P 32 pulses when it is triggered. It also needs a manual trigger (form of a button) which does the same thing. The 32 pulses will then be fed into the register to ensure the bits are on the right pins. Then it needs one final pulse, just for the latches to clock all of the bits into the latch!
This is quite complex and I hope I have explained this adequatly enough for someone to give me some pointers.
