    Re: Ins and outs of the All_Digital directive

    You're right Paul, but as explained in my last post - the display works with the sooner or later to be obsolete directive All_Digital. In this particular case the defaults are therefore reliable I...

    Re: Ins and outs of the All_Digital directive

    Thank you for your input Paul.

    Since I do not define the port that's utilized for the display, the default pins will be used which is exactly the way that I have connected it. It works fine when...

    Some minor corrections to make it complete - missed something there. The effect however is still the same: No working solution:

    Re: Ins and outs of the All_Digital directive

    Hi Harm,

    Well, we have a full agreement on how to handle this. Lets go with some code, might tackle my gaps since I obviously do something wrong.

    Do you refer to the so named "summary of registers associated with xxxx, where xxx is the particular peripheral that is described? I have the feeling this doesn't cover everything, let me...

    Agreed and understould, but it doesn't answer the question.

    I struggle with the pin behavior more then once. When going trough the datasheet, I try to set all registers manually. Basically TRIS,...

    Ins and outs of the All_Digital directive

    The All_Digital Directive was originally introduced, as far as I understand, to set (all?) SFR's that relate to analog port inputs with one single command to a certain state (either analog or...

  11. Re: Strange effects when switching from 16F1783 to 16F1786

    Gary,

    I suppose that this is a bit a pointless request. First of all it is highly dependant from the application whether a device should be avoided or not. Second, device revisions change over...
  12. Re: Strange effects when switching from 16F1783 to 16F1786

    Hi Kai,

    The main question is if and how many devices with revisions C0 have been spread. I'm one of the few who instantly ordered a couple of devices straight after launch, bad luck. Microchip has...
  13. Re: Strange effects when switching from 16F1783 to 16F1786

    Yes, I should have been a little more precize; it wasn't addressed neither limited towards Proton - exactly the opposite truly, meaniong Microchip.

    Might be useless, but I have opened a ticket at...
  14. Re: Strange effects when switching from 16F1783 to 16F1786

    Hmm, I feared an answer like that. I suppose this makes 16F1784/6/7/8 all useless in combination with Proton, since they all suffer from the same issue in the C0 revision....

    It would be easy to...
  15. Re: Strange effects when switching from 16F1783 to 16F1786

    Ok, long story short:

    The All_Digital directive has been in by habit, subsequently I have TRIS, ANSEL and WPU in the code as well. I have left out INLVL, ODCON and SLRCON here since earlier...
  16. Re: Strange effects when switching from 16F1783 to 16F1786

    Hi David, thanks for your response.

    OK, stripped the code further down to get a cleaner image, it looks as follows:

    Thanks John, I've already tried that but it doesn't influence the problem at all. Forgot to mention it; if so many things have been tried already you easily forget to mention one :-).

    I have...
  19. Re: Strange effects when switching from 16F1783 to 16F1786

    Hi Harm,

    I agree with your findings regarding similarity of both PICs. SFR's for the registers that are available on both devices are really the same, apart from order.

    The accuracy of the...
  20. Re: Strange effects when switching from 16F1783 to 16F1786

    @ Harm
    Thanks again for the contribution, always very helpful :-).

    In this particular case, indeed I do not check the TMR0IF flag since it is the only interrupt that can occur, hence, it MUST be...

    Hi Xldaedalus,

    Tnx for your response.

    Inbetween, I've managed to achieve the desired result already (this thread is a year old already), though with timer1 which works like a charm now. Product...
  24. Re: Beginner in this software. Help interpret the source code.

    Hi Clydestyle,

    Since your questions show that you both are rather unexperienced, I would strongly recommend a few steps to learn understand code:

    1. Either install the proton or alternatively...

    PICkit3 - PK3CMD.EXE questions

    Hi Harm,

    Ok, understould. I have not touched the SFR's with respect to the well working 1783 settings and couldn't see pin settings that could influence the behavior of 1786 compared to the 1783...

    Pic-Ignorant: I utilize the default PortB pins with an exception for the EN pin (B.3) and the RS pin (B.2), so actually I crossed them.

    Yes, that was my fear as well. I have cross-checked the registers and as far as I can see, the registers are identical. The only difference I could figure is, as said in my original post,...
  31. Strange effects when switching from 16F1783 to 16F1786

    Actually, the title explains the whole issue already:

    As far as I can see, the 16F1783 and 1786 are exactly the same, apart from program memory, data SRAM and an extra comparator and PSMC. The...

  35. Different behavior of PIC's from one production batch?
