I am in a symmetrical source project with pic 16f886, but in the proteus simulation the voltage values displayed on a 20x4 lcd, and these values are different from the registers in the proteus dc voltmeters.
and the negative voltage displayed on the 20x4 lcd is displayed very fast.
and the positive voltage displayed on the 20x4 lcd is displayed normal

If someone could please review the code and correct it, I would appreciate it and thank you
