    Re: Writing & Reading 2 Bytes to/from Flash

    Ioannis,

    This is getting more complicated than I figured.
    Might you be available to implement this for a fee?
    I can send you money in advance via PayPal.

    Thanks,

    Re: Writing & Reading 2 Bytes to/from Flash

    Richard,

    I tried your suggestion but it did not work.
    As my whole code is >73,000 characters it will not post.
    I am using PBPX 3.0.7.4
    The PIC is a PIC18F27J13.

    Is my syntax / technique...

    Re: Writing & Reading 2 Bytes to/from Flash

    I have looked high and low but cannot see where this is set.
    What exactly is this called and where can I find it?

    (I have the U2 Programmer with version 4.51.)

    Writing & Reading 2 Bytes to/from Flash

    Hello,

    I want to store and recall 2 Bytes from Flash on a PIC18F27J13 for pairing up a remote control to a mobile unit.
    These are RadioID(RF Address) and RadioCH (Channel#) which are both just 8...

    Right. The data sheet says there are (3) ways to clear the "mismatch".
    But, just doing the below seems both simple and direct.

    Re: Incrementing Upper Nibble Only (HighNibble)

    Richard,

    Wonderful! Works beautifully!

    number var byte
    number=number+16 will increment high nibble

    Again, very clean and easy.

    Thank you very much!

    Re: Simple 1 Byte Checksum Method

    It can't be that simple?
    What if there were more than 2 Bytes like 10?

    No it's not a weatherstation, more like a entry door counter.

    Right. That's simple.
    Problem is when they add up greater than 256 becoming a WORD.

    Incrementing Upper Nibble Only (HighNibble)

    Hello Again,

    How does one increment only the upper nibble of a byte?

    Apparently there is no HighNibble or LowNibble function in PICBASIC?

    Re: Proper Technique of Setting Config Values

    Yes, that alternate method is even more cluttered and confusing.
    Raises more rule questions than the awkward but more clearer one-liner.

    Re: Sending multiple serial strings.

    Option 1 is quite logical.
    Why does it "waste" RAM? Could it be stored in ROM instead?
    Option 2 is simple.
    In composing the moves, I do want to avoid typing those long strings over and over.
