    Re: 12F675 vs 12F1840

    Most strange is the 32 vs 4 MHz clock. Lower clock needs more code space!!! I expected the oposite.

    Re: 12F675 vs 12F1840

    I shouldn't but for the sake of the very strange case I will. On both the chips the code is the same except for the port access. Everything else is identical.

    12F675:


    #config
    __CONFIG...

    Re: 12F675 vs 12F1840

    Forgot to change GPIO to LATA and PORT registers.

    Now it counts down to 679 words. But still away from 547 words.

    12F675 vs 12F1840

    I had a test program developed on 12F675 until my samples of 12F1840 arrive.

    Now I transferred the exact same code to the 1840 chip and the size of compiled code went from 547 words to 785 words....

    No problem. I thought that you ended your cooperation with the magazine.

    Re: Nextion LCDs... How to comunicate ???

    Mike, the latest issue of Nuts'n'Volts does not have your new article on Nextion displays as promised on article 5.

    Was this on error?

    Totally agree, but Roger is still using On Interrupts...!

    Re: Help understanding HSERIN/HSEROUT

    Richard,

    I think what you propose is the best solution and ultimately, Roger may follow it.

    But it may be too complicated at the moment to have such an advanced data handling. Or not?

    Re: Help understanding HSERIN/HSEROUT

    I think there is no point in hunting down the incoming SMS as they are available in the GSM module.

    You can once your MCU wants or is available to ask for the new messages, and select the most...

    If the datasheet says it works on 3.3Volts there is no doubt that it will. Trust it.

    Re: 16f1847 hserout

    Do this:

    On page 154 of the Pic Basic Reference Manual copy the DEFINES and test them to confirm that your circuit works as expected at 2400 baud.

    I know it is not exactly what you want but...
  13. Re: HSEROUT using STR modifier - length parameter as variable not working

    Yes, I believe it can be trusted with a variable. I've used this form to receive a variable number of characters based on a length parameter received immediately prior to the...
  14. Re: HSEROUT using STR modifier - length parameter as variable not working

    Unfortunately Charles Leo is not monitoring this forum. I 'll make a post on support.melabs.com to clarify this, since the manual is not very clear on the matter.

    I 'd rather be 100% sure that...
  15. Re: HSEROUT using STR modifier - length parameter as variable not working

    Page 47 of the manual says "STR must be followed by a backslash and a number that specifies how many
    characters (bytes) to collect."

    So, as I understand it, it should be a number, not a variable....

    Example to do the same thing as motion feedback module? I am not sure. Guess not.

    Re: remote code learning

    Or you can write more code to emulate the motion feedback module.

    Tedious I think.

    Re: remote code learning

    You need a PIC with the motion feedback module. An there are not many.

    Sorry...

  21. Re: PIC18F1220 - Variables initialisation placement makes a change

    This is extremely strange.

    If you have other 18F series chip, can you try it also?

    Then maybe on support.melabs.com forum, Charles can see if this is a 18F specific bug.

    Can you post your...
