Greg, I'd like to understand this so I can do the same for the IN-18 design and the next, fifteen digit clock that will use five, HV5530s. Please let me know if this is correct:
Latch, blanking, and data, are connected in parallel, on each of your boards. Each clock line is connected to a separate pin on the processor. How do you clock the data so that it moves across all HV5530s if they are not clocked at the same time? Would it be an advantage to connect each clock and each data line to a separate pin, to load each HV5530 separately rather than serially?
