Hi Guys,

Bad luck i tried changing another Pic16f84a
no work, i tried with multiple resonators and 4mhs with 47 / 10 pf that also doesnt' work.

here is the code file in two formats, probably i will update my cirucit picture tomorrow.
Code :

@ DEVICE pic16F84A
define OSC 4
TrisB = %00000000

loop:
High PORTB.0 ' Turn on LED connected to PORTB.0
Pause 1000 ' Delay for .5 seconds

Low PORTB.0 ' Turn off LED connected to PORTB.0
Pause 1000 ' Delay for .5 seconds

Goto loop ' Go back to loop and blink LED forever
End

and in Hex:
0000- 2828 018f 008e 30ff 078e 1c03 078f 1c03
0008- 2823 3003 008d 30df 200f 2803 018d 3ee8
0010- 008c 098d 30fc 1c03 2818 078c 1803 2815
0018- 078c 0064 0f8d 2815 180c 281e 1c8c 2822
0020- 0000 2822 0008 1383 1303 1283 0064 0008
0028- 1683 0186 1283 1406 1683 1006 1283 3003
0030- 008f 30e8 2002 1006 1683 1006 1283 3003
0038- 008f 30e8 2002 282b 0063 283c


I noticed when i take off the Vss pin then the led is constantly lighting up.
if i connect Vss then nothing comes up. no power in the pins . with the multimeter i checked the pullup capacitor
is giving me 1.24 reading and no power on the pins,

what would be the problem. Is there any way of tracing this where it is going wrong?
