16F872 and LCD

[skimask]

The LCD does not have a backlight becouse it´s an (HD44780) OLED
For 2 years or so i use the same OLED whit an 16F84 and the same code to and then i worked

No it has not an heat sink, but it is capable of 1.5 A whitout an heat sink and that is more then i need.

Know what else might help?

If you bought a legit copy of PicBasicPro from a vendor instead of download an old version of 2.45 from who knows where!
