help flashing a PIC 12F629

[Guest]

Hi; started out just trying to take photos from my r/c plane. Now I am
learning electronics stuff that I knew nothing about 2 months ago.
The circuit that will control the camera shutter uses:
12f629 PIC
hex file from r/c cam man (where the circuit project is)
http://www.rc-cam.com/cammanxp.htm

I have followed the directions as well as possible. read the osc cal value
as 3440 in the last address, then tried to program the hex into the pic,
with leaving the osc cal value at 3440 instead of 3ffff.

I am using a jdm with IC prog1.05c, and have the fuses and intosc set the
same as in their project.

Failed at address 0000h is what I get ???

Tried the winpic800 that came with the jdm, but the WP800IO.sys fails to
instal every time I try to open . The hardware then does not get recognized.

First PIC programming for me. Not sure if I am screwing up, or "system"
probs.
Ideas, besides getting a long extension cord on the camera

see whether the device is getting programming voltage. typically these
devices require something like 12v on a pin to enable the write
function.

The JDM programmer (and other similar designs) use the *standard RS232
voltages to provide the programming voltage for the chip.

Are you using a PC with a "real" serial port (provides true RS232
voltages of +/-12) or a "modern" PC that only provides +/-5 volts or a
USB<-<serial adapter that only provides +/- 5 volts.
