Hello All,
I am facing a serious problem & therefore wanted an immidiate help.
I am driving a 9 segment * 4 backplane with 89lpc936 & a shift register.
My supply voltage for controller is 3V & have kept 1.5v for backplanes.
My problem is that,
when I am putting the data for not glowing any digit as per the attach waveform(attach file), I am getting the dimming effect of the all segments which is unwanted. I am not able to understand how to eliminate this?
