blink a single led

Suspect your breadboard if it is older than 1 year, the sockets corrode and become insulators.

define OSC 64 ' does NOT make the pic oscillate at 64 mhz, it simply adjusts PBP's timing to accomodate that speed, so if you are running at say 4mhz then whatever you expect to happen in 1 second will take 4/64 or 16 seconds to happen. I think your config will not allow 64mhz as you need PLL FOSC = HSPLL HS oscillator, PLL enabled (Clock Frequency = 4 x FOSC1)

HELLO,
Tks for ur idea,
it is true that the breadboard is older than 1 year. but the
however, the same breadboard connection and pcb ( i design it and product it) the pic that was programmed a month before is ran perfectly now
but the same program is burned into the chip NOT RUN AT ALL now ON BOTH BREADBOARD AND PCB

about the osc @64mhz and 4mhz, r really different:
let's say
PAUSE 500 @64MHS OSC : the led blinks faster than
PAUSE 500 @4MHZ (by inspection)
i really do not know the pic runs @64mhz or not. but at this speed, it can handle 6-8 p10 led modules (in my case)
i include a short video that is on the market for several years that i had sold,
i try to upload but fail.
i will reload later

HELLO,
HERE IS THE LINK:

last night i though when the breadboard becomes isolation (due to plug and unplug the chip may times)
so the zip socket on the programmer gets the same situation?

but the programmed chip (last month) runs well right now on the on both pcb and breadboard-
i can eliminate all off the situation then conclude that the programmer fails- but i check the code from the chip is ok (like the code compiled)
now i m like "a dog runs after its queue".

hello every body

finally the program runs as posted on the first post- nothing change- and just go back to another computer (complete format the system...) and run win xp- pbp version 5
tks for all

HI EVERYBODY

the problem came from the computer - but i have had no idea why the program did not run at all. the chip was burned perfect by the programmer-
the code is perfect (checking by inspection)- (the version of the pbp is irrelevant to the problem)

tks all for your help
