The problem is not to make it work - it does.
I want to understand how to modulate the LED's capacitance.
It's maybe more an electronics issue, not a PIC one at this time.
Any idea?
I tried a few different things, added resistors, added small cap's in parallel with the LED, couldn't really get the results to change to get a larger 'range'. The results would 'shift' up and down, but never really stretch out the way I wanted them to.
Are you trying to 'widen' the range of the number you get back from the function? In other words, instead of, say 0-10, you'd get 0-1000?
The key might be finding the right LED vs. adding components to the circuit, or just plain counting it all really fast.
As you can see from my page, basically, as soon as I got that to work, I called it good...something in the hobby toolbox for the future...
