  1. Re: How to remove ghost directory from mocrocode studio

    I do not think this problem is relevant to PBP, but to MCS ( Mecanique )

    you could drop some lines here ;) https://www.mecanique.co.uk/shop/index.php?route=information/contact

  2. Re: How to remove ghost directory from mocrocode studio

    Hi, Sheldon

    there's a nice little program called CCleaner that ... cleans all the unwanted "deposits" and old registry entries from your computer ...

    note you can also keep chosen cookies for...

    Re: Stepper motor question:

    250v applied to +/- 1 Ohm ( NEMA 42 data ) create how much current ??? :rolleyes:

    You were joking, I suppose ...

    Re: Psst, Can You Keep a Secret?!?

    Hi, Ioannis

    Even after a thoroughful cleaning, the problem comes again ...

    Working fine here requires The 5.30 Version ...

    Probably a new Win10 " feature " :rolleyes:

    Have a nice day

    Re: Psst, Can You Keep a Secret?!?

    Hi, Mpgmike,

    just a question about MPLABX 5.35 : Here ( win 10 up to date ) when I close it ... it automatically re-opens !!!

    so, I had to turn back to V 5.30 ... to get something usable.

    Hi, Ioannis

    I didn't receive any notification nor for posts 8 to 11 ... just for the last one ( Yours )

  10. Re: Crystal oscillator variability between PICs?

    If you need high precision timing ... just do use external oscillators like those : https://www.mouser.fr/datasheet/2/96/CTS_11052019_008-0258-0_I_MXO45_MXO45HS-1665263.pdf

    just my two cents ......

    Re: 12F675 vs 12F1840

    Hi, Ioannis,

    I'd have a look to internal registers PBP default settings ( the PBP default Config file ) ... as you overwrite most of them ...

    just an idea ...

    Hi, Flotul

    From the very far I remember ...

    ALL Variables have to be initialized before using them ....

    Only one exception : IF you write variables the first time you use them ...

    Re: breadboarding

    decoupling capacitors are missing !!!
