  2. Closed: Re: PIC18F452. Not able to verify and program device using pickit2 clone.

    Hi,

    Did you try the Tools TroubleShooting with a voltmeter and get correct readings.

    Have you tried Reading the 452, does it return any signs of actual data having being written in the first...
  3. [PIC]Closed: Re: section '.org_1' can not fit the absolute section. (16F628A)

    Hi,

    Don't understand, there is only one Config line in the code I posted and that is from the 628a .template file ?

    All other original code that was changed was left in but commented out so the...

    Hi,

    You did not say what length your output wires are and if you have tried very short ones.

    Also , as Veketti mentions, try the V2.61 Tools and run the Troubleshooting tests to check the...

    Hi,

    Try putting Vee down to 0v , or create a potential divider with 2 resistors to give about 0.7v to Vee.

    Don't think Proteus uses Vee even if you place a voltage on it.

    Hi,

    You need to check your calculations.

    First , what voltage are you running the 628 and BT module at.

    Are you intending to run direct from a battery or via a regulator, if so what type ?

    Hi,

    Mystified ??

    Raising Mlcre pin by +1.5v over VDD is the minimum needed at activate VPP , so as FVM says at 5v Mclre , the chip will possibly enter programming mode.

  17. Closed: Re: Pull-up resistor on micro input pin is too high Ohmic value?

    Hi,

    Many use 10k as the pull up value, though you could go higher if power saving is critical; a 100nf is often used.
    Also depends on the use, are you talking hobby or commercial/ industrial use....

    Hi,

    A software delay loop is based on the number of instruction to complete that loop.

    Does your formula account for the fact that not all of those instruction are completed in one machine...
