Binary sketch size: 183,028 bytes (of a 524,288 byte maximum) - 34% used

So the LDA eample that has slightly different number results but did one calculation correctly i would have to try it with some of the sample data or octave or r example data to see if it continues to work.

Well I got the code to compile for a pc and compile for the arduino due. Now the pc I tested it will this run on the arduino due? Sorry about the mess.

I switched the board type to duo and it must look into the sam libraries folder so now the example compiles. I will try my code latter. Thank You.     

Thanks I downloaded Arduino 1.5 ...
I put the eigen subdirectory into arduino hardware sam libraries then the eigen.h file in there. That is in the adafruit post.

Now I am getting errors with namespace...
using namespace Eigen;    // Eigen related statement; simplifies syntax for declaration of matrices
The print out option of the matrix tipe I am not shure how that works.

I useualy use standard c and arduino c.

I wanted to program the arduino due to do some linear algebra operations. Linear Discriminant Analysis. The code blocks c++ release code is over 520k already So I wonder is their ways to compile the program smaller and will it be smaller put into the arduino due as shown in the forums? It is on my pc now.
What are ways to add more program memory???

I am using the Eigen library and want to run it in the arduino due I have posted some of my codeblocks c++ code for my windows machine.

Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.

Pattern Matching in arduino c++
I don't have the Arduino Due yet but I did write  this code in c++ code blocks on the release compile the size is Output size is 531.00 KB on my windows 8 computer and want to try it in a due. I wonder if the arduino due will be able to hold it and any suggestions to make it fit if not?

It inverts and multiplies and divides a constant from a matrix...

This is awsome and might work with the maple. I wonder if it would compile for fpga somehow like a xillinx.

I am interested in this and want to try to do linear discriminent analisis pattern matching.

The matrix inverse multiplication addition etc is needed for it.

I do not have a duo yet so i will try it in code blocks then on my leaflabs maple then the duo maby.

Has anyone tried this i like their documentation.

    

I checked the wireing the wire came loose I get now 10010010 so I guess it is working I can read from the SPI the next test I will do is read & write to a different register that is read and write able.

this is what it says it should be on the data sheet
010 = ADS1298; 24-bit resolution, 8 channels
the lower bits of Address = 00h
page 39
it is now showing all 1's

thanks andy brown

so what I did is:

• I took the global vareables section pins and vareables.
• coppied it into my function definition sketch
• removed the declarations because it caused a error and they were allready defined in the main function.
• I have not tried running this yet but it would be a good tutorial for the arduino community to have with the examples a 2 sketch main loop and setup and function defintion sketch.

here is the 2nd function sketch I wanted to seperate it because it was getting large but I think that might be causing bugs...

here is the second program in another post their isnt enough room.

[setup]

yea you can all see it it was long so I was trying to be respectful here are both of them their for my open source electronics project talking to a ads1298 ti's biopotential mesurement chip a very advanced ADC.

Also my hardware the sensors board is made in kicad a open source hardware design piece of software much nicer than eagle.

I have a sketch with loop & setup functions & one for my function definitions.

If the pin int is defined in the main sketch with loop and setip will the function be able to toggle it?

I have a program that toggles a serial clock for a spi device and prints out the results all the functions are in a second sketch where the functions are defined.

It is returning all 0's and their should not be acording to the registers on the data sheet.

what would this do with basic blink hello world and buttion sketches?

thanks for adding the details I would have just put
NOP
then
NOP; on a line and scrached my head and started googleing when it didn't work.
It would be funny if it was renamed to LOLCAT NOM. ;D
