    There is several way indeed. Some use Proteus, some MPLAB sim, some use Serial communication (and/or ICD like Pickit 2 or MicroCode ICD), or still some LEDs or a LCD.

    What's the best method? Hard to tell, for me a blend mix of everything above (less Proteus as I don't trust it) do a really good job. And then, it really depend where I am in the development stage and how big the "bug" is.

    An ICD tells you exactly what happen in your code in real life, and more, it give you ALL internal register status, down side, they're usually a bit slow.

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

    Hi,

    Steve is right ... ICD2 or 3 really are great tools, Consider Pickit too.

    16F690 not supported for debug ???

    FALSE !!! for 30 Euros at Farnell, you get the 16F690-ICD Debug adapter ...

    µChip ref AC 162061.

    Then just

    1) plug
    2) play
    3) Enjoy ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!

    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?

    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!

    Default 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.
