Would something like enable_interrupts(INT_RA3); work to only enable interrupt on GP3?

As for the GND connection, as you pointed out it must be present or funny things start to happen...

But what if I decide to use for example the FTDI FT232R should I then connect the ground to the U ...

How do I properly enable interrupt on change for GP3 on the 12F629?

Thanks.

Finally I think I can make my RS232 working.

You could use the [url=http://www.vinculum.com/prd_vnc1l.html]FTDI Vinculum and connect it to a suitable pic.

I'm using bit-bang RS232 on a pic12F629 with is connected without a level converter (such as the max232). Should I use the INVERT option or not?

In the CCS C help I found this:
Check the level co ...

I finally solved the problem. When I connected the curcuit to the external power I didn't connect the VPP line (which handles the RS232 communication), so GP3 was a 0 - and the program was designed to ...

Well I added the current limiting resistors, 56ohm (the reason why I didn't put them in in the first place was that I got the wrong info for them from the site I bought it on). Anyhow I doesn't work a ...

I tried with BROWNOUT as well as with PUT and it makes no difference. Any other suggestions?

I know it's a bad idea to draw current from the serial port - so I do use a bench power supply, and that where the problem comes in. As I said before if I use the power from the serial port trough the ...

The reason why I asked was that the pic is doing strange things, I'm using delay_us to blink some LEDs and when I connect the pic directly to 5V the LEDs begin to flash instead of being illuminated, a ...

As I understood the 12F629 has some kind of [url=http://ccsinfo.com/forum/viewtopic.php?p=111686]reset latching problem and the supply voltage need to be clean.

Is having a decoupling capacitor (0 ...

So I think we can agree that driving 3 LEDs at once is not such a good idea. How about the last code I posted? I'm reposting the last code again with an minor modification to the delay part.

Would something like this work in practice? I have chosen to only light 1 LED at a time because of the risk of overloading an "output low" port. It works in the simulator and I think it will ...
