Swordfish

There are also "transparent" serial-to-bluetooth modules available which once configured pretend to be a 'wireless wire' and need no control from the PIC; just serial communication. I've used them myself and can vouch for their efficacy. A quick search for "serial bluetooth" or "rs232 bluetooth" wil...

Had to re-arrange some of the logic flows--but that's got it working correctly now. Thanks!

Hi! It's possible to use precompiler directives to test Const values and throw an #error if something is amiss, yes? I've got this statement: Const Valid_Click = 256 'this is for testing, normally the value is derived from _clock #if Valid_Click > 255 #error _ButtonHandler, "Debounce value is too hi...

I've been using Swordfish in a virtual XP for awhile now without any tribulations...

It may be the virtualisation software you're using--I'm using Oracle VM VirtualBox under Ubuntu and it has full USB support--once I got it set up correctly it's been zero effort and problem free.

Put an RTC clock chip with alarm function on your board, attach the alarm pin to on of the interrupt pins on your PIC, sleep PIC.

Are you certain your code is correctly interfacing with the clock module?

'0' is what one gets when the clock module is non-functional or communication is not being achieved.

Not sure what's going on with your setup, but here's an excerpt of my ADC code. This code has been serving me in good stead for a few years now. Note: the voltage flex number will vary depending upon certain conditions... 'Actual_V / ADC_Reading = _voltage_flex Dim VoltsBuffer(6) As Word #option _vo...

USB bootloader would have to be huge as it must accomodate an entire USB stack in order to be functional...

For everything I've made, serial-port loading is perfect.

I would LOVE to find some nice, small, easy to use bootloader code... I'll be watching that topic closely.

Thank you!

Sry, should read a little more into your original reply. I think so long as your sensor isn't too greatly modifying the electrical characteristics of the ignition then your proposed method should also work... of course you'll need to take steps to blunt the amperage of the ignition from ever reachin...

Oh!

If your hall effect sensor changes state rapidly enough, then it should be fairly straightforward to wire it to one of the interrupt pins on the PIC.

You'll need a clock or some method of guesstimating when 1 second and/or 1 minute have passed...

IMHO that should work fine.

Isn't there a built-in location for connecting an RPM sensor?
I'd think that would be an easier way to gauge speed...

That works perfectly now! :) Thanks again to Jerry and David. on a side note:- This pic is only supported with the Pickit3 :( Are you sure about that? I've been playing with K-Series PICs for awhile now, burning the code in using the melabs U2 usb programmer (not to sound like an advert... sry). I ...

Oh i see...

Thank you!! I had no idea.

I'd been attempting to write a routine which gives me the 'float length' (eg how many numbers trailing the decimal) and I appear to be suffering an aspect of the same(?) bug.
