I am relatively new to using PICs (or any microcontrollers in anger).
I have experimented with a couple of pic16f variants using PICC lite on a PicKit2.
I think the major problem I'm having now is debouncing the signahttps://www.edaboard.com/#topl pins A and B from the (gray code) encoder.
I...
Thanks for the link - I think I follow the example cct okay.
I am just wondering about the original cct's design - I notice that it has a 2.5mH choke shunting the coil.
Can anyone explain what purpose this has in the original circuit.
It seems to me that there is no equivalent inductor in the...
Here's the circuit:
http://www.cs.berkeley.edu/~wkahan/TransIgn.pdf
It's simply designed to ensure that on an old engine with the spark controlled by points the points will not have to carry the current for the coil.
I have access to some BUV46 NPNs...
Well, I'm going to take an optimistic view and hope that the problem is with my misunderstanding rather than the equipment - although I would like to be able to confirm whether it does work, as I'm holding of leaving ebay feedback on it.
I had scan-read about the PICs producing their own...
I'm wondering if it's my breadboard wire-up now.
The (stand-alone) programmer registered that the configuration bits where not set - which I duly went back into MPlab and set. After that I thought it might work, but....
Basically the error code is, I think, saying that, on trying to program the...
Okay - going to attempt to adapt the Flash_LED tutorial as suggested.
Probably tomorrow now as it's evening time here in the UK and other things are vying for my time!
Will get back to you ppl tomorrow, but thanks again for the immediate help!
bigdogguru, thanks for your detailed answer. And your offer of ongoing support.
As I have the 16f54 sitting on my desk I would like to put it some use, as I'm pretty sure it can manage the simple projects I'll be starting out with. And until I get round to ordering something more user...

So at least the clone of the PicKit2 claims to work with it, and it comes up in the list of Baseline PICs in PICkit2 v2.61 (HEX loader only IDE).
Hi.
I bought this PIC in a hurry and have found it's not very well supported.
But I'd like to get some use out of it, except I can't be sure if it's working okay.
I'm new to PICs - I bought the chip just really to test the programmer I got - a clone PicKit2 (from Piccircuit - PIC Circuit...
It is more a concern about the mechanical aspect of the slotted wheel moving slightly whilst the PIC is 'asleep'.
However it does sound like (having read up a bit more) that I can use Wake-On-Change for this and still enjoy an almost unnoticeable power consumption.
Overall, though for...
Dr pepper - Thanks for the info on quadrature encoding.
The main limitation (not major one) with my method is either the operator has to 'zero' before starting the dial-in the sequence, or the PIC has to be in a state where it 'remembers' it's current position. And even with it remembering I...
Okay - I've got a PIC programmer on on order and have been reading up on the assembler/reminding myself how assembler works.
In the meantime I am thinking about a slightly different project on similar lines.
- I have an old dial off an old and cheap combination padlock.
- I also have the guts...
