@Ttelmah -- the supply seems to be pretty solid and noise-free -- at least for the moments I've looked at it. And I don't offhand have a way of measuring the supply...unless I can (somehow?) just befo ...

Thanks for the reply Andrew.

I'm afraid I do have BOR enabled.

Seem to be having trouble with eeprom write or read in PIC16F18345. Using it in a device where the user has the choice of a few settings. When (and only when) the user pushes a button to change setti ...

Hmm, OK. Thanks for the input. I'll ponder on it while I try to flee from the mighty saber-tooth cats.

As it turns out these are 12V LEDs, each switched by it's own transistor in an array chip, wit ...

Hi again. Back with another dopey newbie question. Please administer 2 aspirins before proceeding, to offset head-to-desk banging. As always, preliminary thanks and apologies up front.

OK, I've got ...

It's a phototransistor. I *seem* to be connecting it as recommended by the manufacturer and some examples online. Surely it's just me being a dolt, trying to hammer it in with a rock or something.

Ah, right. Embarassed

I had changed that in panicked random button pushing. Thanks!

And yes, that did help greatly. But...still have a problem with the pin pulling down the voltage too much. As soo ...

Hi all, and a preemptive thanks.

I'm new to ADC, and trying to use it on a PIC16F18345. The trouble seems to be that the pin I'm trying to use for ADC goes into a permanent pull-down state. Any vo ...
