symmetric power supply pic 16f877a

[josepic]

I have solved my problem of flickering of the negative and positive voltages, change in the source code the pic 16f877a and use the pic 16f886.
the only thing left for me is to buy pic 16f886 and design the pcb for the symmetrical source and present the project to the university.
I really received little help in this forum

Depends on how one is looking the case.

Richard did his best nailing your problem and suggesting a solution. If it is not what you expected, well, OK.

In any case this forum helped many and does have a whealth of info and solutions.

Sorry you feel that way.

The solution provided by Richard did not solve the problem for me, I had to correct the following in the code:

'++++++++++++++
'pv LCDOUT $FE,$A3," clean negative voltage
LCDOUT $FE,$A3
'++++++++++++++


'++++++++++++++
'pv LCDOUT $FE,$E3," " clean positive voltage
LCDOUT $FE,$E3
'++++++++++++++
