pass pic basic pro pic from pic 16f877a to pic 16f887

[joseluisatmega8]

hello I sent you the following link of the video of the simulation in proteus of the symmetric source with pic 16f877a, and you will see that the values of the voltages and negative flash a lot and do not remain fixed.
I know that the replacement of pic 16f877a is pic 16f887, and I want this same code to work with pic 16f887.
In addition, this was a work that I presented at the university in my digital electronic subject and obtained a 4.0 as final work.
Here I leave the link

And thanks again

in the simulation in proteus on the 20x4 display in the positive and negative voltage blink a lot and they are not fixed, and I have not been able to correct this fault

thats not even a close description of what i see in the vid


i see an
incompletely described pgm with no config settings
performing an undescribed task
in an unspecified circuit
that when simulated in an unspecified environment
performs not as hoped for(what ever that expectation is)


who would have thought it ?
