    Re: GOTO vs RETURN after a GOSUB

    Also, using GOSUB reduces code size as this Sub can be called from various points of the program to do the same job, maybe with some parameters passing to it.

    Keeps things structured.

    Yes, I posted the default. I tried lots of combinations but was trying to get this chip to run at 64 MHZ, when the max is 32.

    You guys are right as usual. It had define OSC 64 for historical reasons.

    Re: Cannot compile 16F15345

    What jumps out for me is you say you are using a 16 MHz external oscillator, yet in your CONFIG statement you list:



    _FEXTOSC_OFF & _RSTOSC_HFINT32

    Your CONFIG should have _FEXTOSC_EHC &...

    Re: GOTO vs RETURN after a GOSUB

    If you want to be a cowboy for some reason you could have used GOTO instead of GOSUB.
    Then you could GOTO back as well (instead of RETURN).

    The difference between GOTO and GOSUB is that GOSUB...

    Re: Oled

    KS0108 controller is very “like” in it’s interface to HD44780. So much “like” that it’s exactly the same.

    LCDOUT could certainly be used exclusively to control one, except the actual commands are...

    is not a config error , the problem lies in the code not posted , somewhere an

    Can't find anything on forum.

    The default config doesn't work, nor any of my attempts to fix it.

    What everyone else says, plus:
    Declare a ground star point and make all grounds radiate from that point - no daisy chains.
    You should be able to trace ground noise origin with a scope....

    Re: Input problems with 12F629?

    I just found my problem. It was these two lines

    SYMBOL RTOUT = GPIO.4

    SYMBOL PEIZO = GPIO.5

    I had changed my board on the last run and forgot to change the pin numbers in the code. The...
