gnupic: Thread: 16F876

Is there any special architectural reason why gpasm and gpsim don't 
support the 16F876 yet, or is it just a matter of filling in a few
parameters?

Also, does anybody know of a DIY programmer for the 16F876 which will do
low voltage in circuit programming and ideally works with Linux?

BTW, the link on gnupic.org to the gpsim sourceforge page is broken.

Alex,

Although I haven't had the chance to try others, I've found the Dontronics
DT001 programmer (http://www.dontronics.com/dt001.html) to be a great
balance between DIY and purchased programmer.  You buy a nice PCB from
Dontronics and populate it with a few components and you have a Tait-style
programmer.  If you decide to take this route, you might want to pick up a
DT106 that is perfect for the 28- and 40-pin 16F8XX parts.  Although I'm
not too familiar with the '876 (yet!), I'm using an '877 in the DT106 right
now.

As far as linux programmers go, I've been helping the development of jpp877
(http://www.kingdon5.freeserve.co.uk/jpp877/jpp877.html) and use Linux
exclusively.  This software runs under both Windows and Linux (written in
Java).  The Linux version currently uses /dev/port to access the parallel
port; although I've almost finished a native library for linux too.

I'm working on expanding the capability of the software to include support
for lots of processors (12C509 is already working) and a host of other
programmers (I've added an oscillator to the DT001 so that it works in a
manner similar to the Prog84 programmer).  While it will always support
command-line operation, I hope to offer a GUI also.  All this is GPL'ed
open source.

Later!

Added in 0.8.14

It works for me. Try again, because sometimes Sorce Forge is unresponsive.

Great, thanks.

What I found yesterday was that the page was blank when accessed via
https:// but it worked when accessed via http://. It seems to work using
either protocol now.

Another thing I just noticed is that gnupic.org links to
http://gpasm.sourceforge.net/ as the gpasm home page, which lists 0.8.10
as being the latest release. It also links to the "sourceforge project
page" at https://sourceforge.net/projects/gpasm/ which lists 0.8.9 as the
latest release. I didn't realise there was a release later than 0.8.10
until you announced 0.8.14 just now...

yep, it's easy.. you just own the source or ask nicely if the author wouldn't 
mind lending it to you for some absolutely innocent curiosity curing.

other than that... you should have the code or it's not yours.

hmmm..... what's your name son???

I wouldn't hold my breath waiting, then again it was from a Windows emailer, and Windows
file security has always been less than easy to manage except for those with deep pockets.

Could try programming without the protection......., did see a file on the 
net about getting code out of a c84 thats protected. But probably of no 
use.
