JDM Power problem - miketurner772003 - Apr 8 8:13:00 2004

I'm trying to program a pic12c509 with IC Prog through a baby
programmer, but get the following message when I try to program all.

"No oscilator calibration value found do you want to use the value
from file OFFFH instead?"

Whether I click yes or no it goes through the motions of programming,
but gives me a message at the end " verify failed @address ooohi"

I believe it's a power issue as I can't see what else is wrong, but
I'm wondering what can be done about this. I have read about powering
JDM programmers with bateries but I'm not sure how to adapt the
programmer to do this. What else can be done about power to the
serial port??

I suspect it is not a power problem: inside a PIC you must write the
type of the external quartz crystal (if you use one) or ht RC
oscillator. This type can be set up inside a file or can be choosed
from ICPROG interface .... read docs about quartz crystals for PIC
provided by Microchip.

Thanks, but this is all well above my head. I have no experience with
chips. I bought a baby programmer (the first one here
http://www.electronic-devices.net/Programmers/programmers.html )and
thought I could just plug it in and program a PIC 12C509 chip, but I
can't make sense of the tech speak about crystals.

I'll have to concede defeat and ask someone to program and send me a
chip.
