You're kidding!
In their wisdom the authors of PBP gave you a DEBUG command which can be directed out to any spare available PIC pin...
Add a penny Resistor and you're communicating with your PC.
Can it get any simpler?

This sounds *just* the job...have you some linkage I can consume please?Originally Posted by Melanie

The linkage is to your PBP Manual... use the really complex schematic provided in the DEBUG section.

Whoop...there it is! (with a whopping one component count)
Can someone talk me through the circuit? (just kiddin')
I'm so excited, I'm actually thinking** about getting a round in.
Many thanks,
Hank.
** ....I've now thought about it - maybe next time!

Debugging code
Hank, it sounds like something similiar to what I have been working on as well with regards to working with an ADC in value. I've been using a serial connection to my 16F877/16F877A. Just like you at first I had a little LED turn on with my ADC value coming in from a pressure transducer. I set it up to turn on portc.0 at 1 psi then portc.1 at 3 psi etc... Like you said that just confirmed it worked. The real work was in taking the value and converting them to a PSI value. I got some great help with that calculation and ported my actual PSI to the serial port so I could see the actual value. I had a tone of SEROUT2 commands dumping everything to a hypertermial session.
I have the schematic for the connection with the max232 rs232 chip if you need it.

If you have PICKIT there's no need for any RS232 level shifter, no resistor either... use the USART tool.
If you're a bit clever, you'll design your thingy to accept ICSP. And then you can also use those ICSP line for Debug with PICKIT.
That's an handy tool for less than 50$.

It's not a bug, it's a random feature.
There's no problem, only learning opportunities.

I uses ISIS. It simulates the code right on the computer, complete with SPICE for the electrical schematic. With PBP, I've got to watch the compiler asm output, but I can see all of the variables change and i/o pins as fast as I want, with breakpoints. When I use Proton+, I get to step through the basic code, one basic line at a time. It even gives me the option to see the assembled code between each basic line, and step through that, too.
