help me please –
Hello I have built the fluffy 2 programmer and the voltages are acording to what the webste said. I does work and everything i cool. The only problem is that today my sx28ac/dp have arrived and when i tried to program one with the fluffy, it done programming and while verifying, it gave an error at 000h
Could anybody help me?
Also when i retried to program it, nd even tried different codes, it gave me an error of OUT OF RETRY.
Is this chip like the 12c508 ?? only 1 program ?
Yes ALL the tests passed. but the problem persists.
Could it be the wrong pins? but then again, if it where wrong pins, would it finish the programing section and start verifying? and then give me the error at the last moment of verifying? also could it be the 18v power supply?
i bought the sx28 from a friend who bought them from usa ubicom. about pin 27 im gonna check now
damn. i tried to check what the voltage is on the chip. from pin 4 (ground) to pin 27 that you said....
while the programmer is on, there is no voltage. and when i try to program it, it gous up to 12.17v and when icprog gives me the OUT OF RETRY error, both leds will be on and the voltage will stay 12.17v until i cancel it from icprog.
What could go wrong? remember im giving it 18v
also i forgot to tell you, ALL THE tests on his web site passed. and i checked the connections to the pc .... they work
they are, upper hole nearest to the 232 chip is pin 2.
the middle is pin 3
and the hole neasrest to the 16f84 is pin 5
I did them in a new small serial port not in the old big serial port.
hmm i just tried giving it 12v and its the same!! could it be the 16f84 has a bad vertion of code? could you pleae mail it to me the righto ne ? pleasE? thankyou very much
ok i have programmed that hex into the pic and will now try it out. also could you please tell me the settings in icprog 1.05a please ?
i really apriciate this m8
ok tried it out and it the same problem. but at least now i got the same code as you do !! also the voltage at pin 27 is 12.33v now!! with the 18v supply.
i tried reading the code and it read althou notin special sine i protected the ic.
I tried verifyin and it verified wrong in adress 0000h
I tried programming it and it gives me OUT OF RETRY.
I tried eresing and i dunno what happened. it said device erares but the leds didnt get on !!
also did you put FLUFFY as an option in thep rogrammer?
damn i tried it 6 times and like 20 more yesterday !! i got same pic code as you do now!! i got all the tests good, i got conection to pc good. i dunno what could happen. i will try with a different pc .
thankyou for your time and help.
