today i started to write a code in assembly to multiplex two seven segment but befor strating work i get an another porblem with a common anode seven segment display that it glow without giving anode supply. i giving a snap of that. and after that i also test seven segment without anode voltage but not with 8051. it work a expacted. i want to know why this is happend
That would be some glitches in the software. Have you tried replacing the display with some similar model? I used SEVEN_SEG_DECIMAL_COM_K and it worked as expected.
