Olimex quad 7 segment LED testing notes


























Now I have completed the boring point to point soldering of all the 4 HC595 7 segment led drivers.  I have also independently tested every one of the four drivers OK.  Next step is to see if I can driver all 4 LEDs using only three signals, Serial Date Clock, Serial Data In, and Latch Parallel Register.
