Thank you, but I've tried for many months to accomplish this, and of course I've used Google for searching and reading documents for a lot of hours on the subject.

There was one search result I hav ...

Hi all,

I'm trying to make a metronome using the internal oscillator of a 16F628A. I have the option of using an external crystal if I should need one, but to keep things simple I'm trying it this ...

To answer my own question: PIN_A4 is a open-drain pin and also can't be used for the Digipot.

I used pin A2 instead of A4:

#define CS PIN_A3
#define SCLK PIN_A2
#define SI PIN_B0

And now ...

The force sensing foot switch is just a fancy 20K linear potentiometer. The B25K pot was just to show how the connections work fine.

The digipot now works, but I can't change it's step value. It se ...

Thanks for your reply PCM Programmer.

I've checked the datasheet and pins before posting, but I couldn't find anything wrong with the RA5 pin. I totally overlooked that it can only be used as a inp ...

Hi again everybody,

I'm trying to replace a foot switch (working with force-sensing resistors) with a MCP41010 digital potentiometer connected to a PIC 16F628A to control a device. It's connected w ...

Don't forget to add a debounce routine, otherwise it may think you've sent multiple button presses.

Thanks. I'd already thought about that, but I'm not sure how sensitive the buttons and transmitti ...

Wow, that worked!

Thank you very very much, PCM programmer! You've saved me from many troublesome head-spinning days and nights Very Happy

Next step is figuring out how to add some buttons etc.

Do you have a 20 MHz crystal and two 22pf capacitors installed in the
recommended circuit configuration, on the two oscillator pins of the PIC ?
If you can't make something simple such as a blinking ...

Hi everybody! I'm very new to PIC programming. I've done my first projects with blinking LED's etc. a few days ago and it all worked fine.

Now I'm working on a new project where the PIC has to send ...
