hello Guys
i had some problems with trying Pic 16f877 for first time but now its ok with help of you
i've built a new board to test my project but now it works good only when i touch the negative line by hand.
do i have to connect the unused pins to GND or Else ?
any idea guys
What type of frequency ( internal or external) you are using to driving your controller? If it's from external crystal..check suitable capacitor and check crystal output. And yes MCLR pin should be pull-up with a described #2 post resistance value or other.
My Board is working now
i had some projects on 12Fxxx& 16Fxxx & id didnt connect anything to MCLR
but im thinking now maybe i've used MCLR pin for input or output
