hi i am trying to control an 8x8 matrix of rgb leds using 4 74hc164 shift registers. the problem i’m having is that only one of the shift registers are outputting at one time. the code im using is:
but there is only input coming from the second shift out. it is as though the first shift out is being overwritten by the second one. all the shift registers are working individually. im using separate data pins for each shift register but a common clock.
any advise would be appreciated. Thanks
