This is quite interesting, as the flowcode does indeed work as you say.<br><br>Now I'm at a total loss, though, as to why the .cod file I was using doesn't. Under gpsim's standalone interface it seems to work perfectly. Since this was a test of KTechLab rather than my understanding of PIC code I used an example from this web page: <a href="http://www.micahcarrick.com/04-19-2005/pic-programming-linux.html">http://www.micahcarrick.com/04-19-2005/pic-programming-linux.html</a><br>
<br>Oh, um, if the chip doesn't have V pins, isn't that a little unrealistic?

No, the're not needed. Something else is the problem. I've tested it with the SVN version and works for me (tm). :)<br>
<br>
The PIC component can be simply dragged in a circuit, press the load button, load your program, then press the "play" button at the bottom of the PIC. After that the voltage on the pins of the pic should change.<br>
<br>
I'm attaching a flowcode that makes 1 pin of the pic change its state in 0.5sec.<div><div></div><div class="h5"><br>

It doesn't work, so presumably they are needed. I could find no other pins<br>
that would do the job.<br>
<br>
Could it be that this is an oversight in whatever template or other system<br>
is used for PIC simulation? Would the fault lie in gpsim?<br>

I guess the supply pins are not needed. You could simulate the circuit<br>
without them. Or it doesn't work?<br>

I've been hoping to use KTechLab to learn a bit about PIC programming<br>
without having to actually invest in the hardware yet. To that end I loaded<br>
a simple program into the PIC component in the circuit designer, just a<br>
little LED blinker for the 16F627.<br>
<br>
The problem is that, although pins RA0-7 and RB0-7 were present, there<br>
were no V pins! Consequently I could not power the chip in the simulation.<br>
Why would this be? What can I do about it?<br>
<br>
Thank you.<br>
