Hi
I have read a guide on how to install plugins to the mplab x on a Mac- of ccs c.
Now, after installed, I would like to install the ccs c complier to the mplab x, but on a Mac. Is that possible ? ...

the internal pll - i did not heard about that , so if its exist- why people still performing an fft, or at least trying to do that ?

and how the internal pll has the enough space for all the sample ...

lm567 by the way, does not have 200hz resolution and can't be tuned a head for a few frequencies . (i must be tuned to f1 f2 f3 f4.. than looking for each to come) .

zero crossing is for children (no offend but thats true .)
When i said one signal at a time i mean 1 main signal , if there will be some noise-the zero crossing is worth nothing. an fft is a must at ...

Thanks T.

Well pll is great idea but i have 2 problems with that :

1. our circuit has to be mass production , and a pll is expensive isn't it ?
(compare to a few transistors )

2. i couldn't ...

Thanks to all of you for your answers, it helped me a lot .

As you said, i have to define to you more about what we do .
Well , we need to send a DTMF signals at the frequecies of 16-18khz.

At ...

Thanks both .
I guess its little bit hard with a pic but i know of many examples on the net, of people that did that even with pic17f .

I guess that some simple algorithm such as goerzel is reason ...

more data:

1. it should not be in real time, but even picking the data for 1 second, than perform the fft, is great.

2. the frequencies are 16-18khz (mic is good for that).

3. the fft resolut ...

Hi.
Using a pic, i need to get the signal from the analog input, that will be generated from a microphone in a small distance.

To get the signal i will set only a microphone pre-amp with one bjt t ...

John , my question is regarding the use of I2C with pic mcu , and as you know hardware and software are connected and work best together .
If you read my question you would see that i was looking for ...

Continuing my other question, we want to check a few things on the lab, and I found the color sensor of Sparkfun:
https://www.sparkfun.com/products/10701

It uses I2C, that i know most of the pics ...

Mike there are answers to all of your questions, just read them .

Second, "10 years of code" ? well, our last start-up team (2 people) did that in a year to be a product. it was far more ...

The fact that you define it as impossible , does not really says anything to me .

First my last start-up , did exactly that : you hold a small ball, you can dance with it in a room how ever you lik ...

thanks for all of you .

Well , i guess that a camera trying to find a certain color , must have a lots of matrix calculations filters,noise and more .

What i need is to blink some kind of a very ...

Thanks a lot for your answer, i will be happy for some explanation on why is it important so much.

The spot is somehow fix, because its an object that one hold in his hand for a few seconds, so , i ...
