For me the only thing that matters is that the chip is old enough to be supported by MPLAB. MPLABX is or will be the reason to switch to something else. There are cheaper and more powerful options wit ...

For example, 18f46k22 costs less than 5€. If this is a one-off thing, it will be way, way cheaper to invest those 5€ in it and not into 200 hours of development time just to go around the limitati ...

For the forum. What is working and what you did to make it work? Maybe your code? It will help others for sure.

False contacts? Do yo mean debouncing?

Maybe this could be under sticky. The code does what you wrote, not what you thought it would do

As always, the basic 1s blink led is useful to tell if timings and settings are ok and that your Pic is alive. An example is maybe two threads down. So two questions. Does your Pic work with the desir ...

Not entering and not working correctly isn't the same :-). How do you check if the interrupt was ever fired? In your code pull-ups are not enabled (commented out).

As a side note. Main should do all the heavy work, interrupts are there just to tell the main what to do. It depends on what you are trying to control, but it is always a good idea to run your pic as ...

Maybe I'm wrong, but I feel that your logic is not the soundest here. What is the point of checking if the interrupt is active once you are already there? It seems by the way you coded it, it will arr ...

It means thanks for the info in Turkish :-)

I'm afraid AI is attacking. Call me old, call me paranoid. But there is a movie called Strange Days. Where they say: It is not a question whether you are paranoid, the question is if whether you are p ...

At odds to be an ignorant. You have a very fast changing input, telling you where the stepper should move. But no one knows compared to what. A kind of unusual scaling factor coming from an even slowe ...

I hope I understood your problem correctly. Compare two numbers, two series of ones and zeroes. Then an action based on that. Float is just an interpretation, but the actual registers don't hold float ...

Hi,

By all means, switch to a faster PIC. There must be a way of doing it with integers. Could you show an example with real world numbers? What you read and where you want the stepper to go?

There is also a debugging aspect. I like to be 100% confident my hardware works. So when I chase down the issues I can be sure it is because of something I wrote or didn't read the datasheet as I shou ...
