JDM and IC-Prog 1.05c - tdanro - Aug 31 6:43:00 2003


Hi,

I'm new to this list. Even after a lot of search through the archive
I'm still unable to program a PIC16F628 with a JDM interface using
IC_prog version 1.05.
It seems that they are several versions of the JDM interface. I have
build the one at:
http://www.lancos.com/e2p/Jdm-v22.gif
I have tried to put pin 10(RB4) to GND, as sugested in one of the
mails from this list.
I have tried with both Direct I/O (with the supplied driver) and
through Windows API.
I run the application under Windows XP Pro SP1.
It pass through the programming procedure and after the verifying
phase I get Verifying error at address 0000.

Can you suggest me what to do?

Thanks a lot,
Dan
P.S. I was able to use NTPicProg.exe (under Windows XP) and a
Ludipipo type interface to program the chip, but that application is
just for PIC16C84 and it supports only 1KB of memory.

jdm and ludipipo are pretty much the same
you may need to invert a lead (or two) in the ic_prog setup

Hi,
I have tried to invert in every possible combination without success.

Any hints?

Thanks,
Dan

On the 12F6x and the 16F62X chips you have to hold VDD high before
raising MCLR. The JDM programmer brings them both up
simultaneously. My guess is this is your problem programming the 16F
chip.

This might be true according to (current) Microchips specs, but in my
experience the vpp-before-vcc sequence is needed only when the /MCLR pin
is configured as input pin, and IIRC never on the 16F628 (without A). In
fact the oldest programming spec for the 16F628 did not mention the
vpp-before-vcc sequence.

..but then.... why ICProg states that it supports JDM programmer too?

Thanks,
Dan

Re: JDM and IC-Prog 1.05c - jrem123 - Sep 9 9:30:00 2003

because ICProg does support JDM. But JDM doesn't support the newer
Pic programming specs.

Re: JDM and IC-Prog 1.05c - jrem123 - Sep 15 8:05:00 2003

I believe (once again) Mr. van Ooijen is accurate: reconfiguring
MCLR (on the 12F62X) so it is not an input alleviates the programming
problems when using INTOSC. At least that's my findings . . .
