    Re: Erroneous mathematical processing?

    BTW: I tried compiling the same code but with the "Use Compiler Long Words" checkbox un-ticked this time in the Microcode Studios settings.

    Still erroneous results, but curiously different:

    Re: Erroneous mathematical processing?

    Copy and pasted into a new inc file but still no luck. The hyp is different but still wrong.

    Re: Erroneous mathematical processing?

    Richard,
    Thanks for the tip. I've modified my trig file accordingly. Alas though, it didn't fix the issue with the ...K83 though.

    Re: Erroneous mathematical processing?

    Okay here is the code for the PIC18F26K22:



    include "trig18.inc"


    Define OSC 16 'Clock will be configured to 16MHz
    OSCCON.6 = 1 ' Set Internal Osc to 16Mhz
    OSCCON.5 = 1 ' Set...

    Re: Erroneous mathematical processing?

    Richard,
    No, it was just a comment. The solution for me was to use a different 28 pin PIC which I had no problem with.

    Nevertheless, I think it's importand to put these issues on public record...

    Erroneous mathematical processing?

    I'm currently doing a project that involves 2 separate pic processors on 2 separate boards doing completely different things. One of the boards is more avionics based and one of its tasks is to...

    Online DAQ suggestions

    Anyone have any suggestions for either an off the shelf solution or something with minimal development effort that will allow me to plug say 1 or 2 0-5V sensors into and allow me to bring up the...

    Re: Serial Sharing

    1 more quicky: so, if you chain 2 or more utilising the "open" state - I'm assuming that the open state is keeping them in high impedance mode when not transmitting - do you need a weak pullup or...

    Serial Sharing

    I have a system with 2 PIC processors and 1 RF module with a serial interface. Question is: can I connect both PICs to the input of the RF module to broadcast from both (not at the same time...

    Thanks again Richard. I might have crack at a bleeding minimum overhead routine over the weekend and see what happens.

    Yeah, it's basically to generate a time stamp in say (1/10 sec resolution) for the data being sensed and packaged. The entire duration of the acquisition period won't be any more than 5 minutes and...

    DT Elapsed Timer Question

    I've experimented with DT's elapsed timer on a PIC18F26K22 @16MHZ and modified the code to send the output to a serial port as opposed to LCD screen. I've found that the timer is counting perfect...

    Re: Quick DTMFOUT Question

    Ok, to answer my own question (I've recently revisited this) you can't use the DTMF command for any oscillator frequencies between 20 and 40MHz. If say I'm using a 32MHz osc and declare that with a...
