So change RBI to be tied low and RB0 should be kept tied high for 0 to display....BI/RBO is wire-AND logic serving as blanking input (BI) and/or ripple-blanking output (RBO). The blanking out (BI) must be open or held at a HIGH
level when output functions 0 through 15 are desired, and ripple-blanking input (RBI) must be open or at a HIGH level if blanking or a decimal 0 is not
desired.
i have connected the BI/RBO to low
the problem still occur ....
The defaults should be OK.do i need to change the on current and forward voltage drop for the 7 segment LED common anode display?
