I have built a laser data transmitter and receiver for my final project.
The Instructor wants to select the bits manually and to send them across the room to the receiver. The problem I am having is that the receiving SI/PO IC is not latching the data and keeping the LEDs lit. I am using a One shot on both sides to send 8 clock pulses the receiving end receives the first bit to start the clock the second bit goes to the SI/PO. Currently it blinks and everything is gone. I have adjusted the clocks so they are exactly the same.
Thanks for any suggestions or help in advance.
P.S. I have already presented this and the instructor was happy that I was able to send data. So the grading is already done. I just want it to work right before I tear down my protoboards
Heres the schematics
