Config problem PIC16F886

[skimask]

Have a code how runs nice on a F88 - thats why I think something is wrong with configuration word for the F886. It seems that I need to touch the probe 2-3 times or reading in more than one time before it reads correct. After one good reading all works, looks that it stops up and needs to wake up before it works????

Since an F88 is an 18 pin device and an F886 is a 28 pin device, it sounds to me like you've got a hardware problem, a grounding problem most likely since you have to actually touch (ground) the device to get it to work for you.
What are you building this circuitry on?

Have ordered some PCB's for prototype testing from PCBCart China - have checked if there is any grounding problem and all looks O.K. Have now changed the code so all variables are reset in the beginning of the code and used the same code from F88 except CONFIGURATION word and now it runs nice. Will test same days then I know for sure.
