gnupic: Thread: Hello, new on the list

I've been using gnupic and gpsim for a while now..
very happy with them.

I'd love to hear when the next version of gpsim is
coming out and what new stuff it may include.

What programmers are people using out there? I'm using
a PRO-16 programmer, but I have to use it with windows
:(

Cheers,
Brent

Hi Brent,
I'm using a home built LVP for 16F627 as written/modified by our very 
own Byron, runs on Linux and works a treat..

Looks nice! I haven't researched it much, but it now
appears to me that the 16F87x series doesn't require
the high voltage programming environment that a 16F84
would need. That's perfect, because my project is
targeting either a 16F876 or 7.

The info on the 16F628 being a replacement for the
16F84 is also very interesting.

Hmm, the circuit is so simple it seems that you could
quicky breadboard one up instead of making some PCB
artwork. Has anybody done some artwork for this
already?

Thanks very much,
Brent

Some bug fixes for font oddness.


I recently added a stopwatch window.


I was also planning to do some kind of waveform viewer, but I
came to the conclusion that it would be a waste of time to
create yet another viewer. So I instead added a file format
for trace data that gtkwave can read. This is enough for my
needs. 

Perhaps a simple and easy to use and limited viewer could be
useful. It could perhaps have a feature for creating/editing
stimuli. Of course, it would support both analog and digital
waveforms. 


I'm currently pondering about creating a non-schematic based 
net/stimuli/modules configuration editor.

Be aware of the cost though. If you use low voltage programming you lose the
I/O pin that selects the programming mode. Even worse this pin is PORT B, pin
3 on the 16F87X parts, which means that it's in the middle of a perfectly
usable 8 bit port.

I try. The only conceivable downsides that anyone can attempt to argue are
availablilty of the new parts and the fact that you can't drop in code for
a 16F845 directly into a 16F628 without a coupl of very minor modifications.

It's on my laundry list of things to do. However I want to PCB it right, so
I haven't yet tackled the project.

No problem. Glad that the TLVP could be useful to you.
