No in built function? That's a pain.

Final question then on this, I've been looking round on ways to select bits that I want to put into the resultant co-ordinate.

I've found something called bi ...

The documentation I have used is this:
http://alumni.soe.ucsc.edu/~inio/wiipaper.pdf

If you look at section B.4.2 that shows the format that the data is in.

However after using bit_test and bit ...

MPLAB Simulator? Not heard of that at all.

OK, so for the first point the three bytes are, for example:

X LSBs 11001010
Y LSBs 01011010
Size and MSBs 01000100

So, to ...

Right, I finally have the correct data!

However, it's not done in an elegant form, I'm having to literally bit-test the bytes and then bit_set or bit_clear the data.

The data is in the form of 8 ...

I'm an idiot. My restarted code had the function for intialising the camera, but didn't actually call that function.

So now I'm at a good stage I think. It's reading data, it's giving it up to a ma ...

Have included and still no joy.

Every single time it does the if statement, it sets the bits, all of them.

Well, I've created a new project, so as to clear out all the bits of code I've tried here and there. So I'm focusing on one point only, initialising the camera and reading it.

I started off trying ...

int out_data[12];
int i;
int x1, x2, x3, x4;
int y1, y2, y3, y4;
int s, s2, s3, s4;
int result;

Those are my declarations. So that explains why I need int16 then.

In the code I gave, s comes from 5, because that is the second point, should have just given the first.
The 12 bytes start from 0 and go up to 11.

Therefore:
x1 - array 0
y1 - array 1
s1 - arra ...

Tried int16 and no go.

But thought more about what that snippet above means and think it means this:

For one point, 3 bytes of data are sent. This is split up into the following format:

1st b ...

Blob size is just the data that tells the PIC how large an IR source it has detected. So if it's a smaller blob, then it's only just about catching the point, it's a weak source, or a large blob is ve ...

I have used that also. The reading the data off the camera isn't the problem, it's how I'm taking that data that has been read in and interpreting it.

The code there stores the data in an array of ...

Here's a link for the source code I used:

My code is pretty similar to it, apart from some changes to shorten ...

Hi,

I've been working on a Pixart Wii IR camera for a project. So far I've managed to pull off data from the camera, which all works.

The data is being saved as bytes from an i2c line. However, ...

Thank you for all your help. I will read carefully.
