For My roof led project, I am using 8 shift registers (74hc299) along with 8 uln2803's (to provide the 20mA/led).
I am working on making an easy way to control different patterns with a microcontroller. I'm planning on using some multiplexers connected to the Data in. Now here is my question:
Can I just use a 8:1 mux (I think it is a mux, 8 inputs, 1 output) and have the output connected to the shift left and Shift right inputs? (see picture). Then I can control which way the bits are shifted using the So and S1 on the 74hc299.
