can any one help me in programming PIC 16f84A

[Elektor]

i am new to pic programming.I am using noppp to program pic 16f84 and want to use all porta pins as input pins.But so far i didnot get suceeded.
I am designing a logic based device with it.

you did not get the program into the pic??

Did you try Flashing LEDs? That's the First step...
Please read https://www.electro-tech-online.com/threads/circuit-impedance-loading.15292/ and look for Nigel Goodwins PIC tuttorials! They Will Help You!!! 8)

inport to pic

i have tried "flashing LED program and suceeded.I also suceeded in making binary counter via pic but failed to give input to pic using LDR (voltage divider with transistor as a switch)
can any one send me a simple program with one or more pin used as input.

Check my tutorials!.

The 16F628 used is the replacement for the old 16F84, any changes required are EXTREMELY minimal.

Try this, it's for 16F84A @ 4Mhz, noWDT noCP XTosc.
8 LEDs are connected to PortB, active High, 4 switches are connected to PortA 0 -3 , active High.

Pressing the switches starts different LED patterns.
