Arrays with two or more dimensions are known as multidimensional arrays and can have more than two dimensions. The following figure illustrates a two-dimensional array, a. The array contains three rows and four columns, so it is a 3-by-4 array. In general, an array with m rows and n columns is called an m-by-n array. Demonstration of an Aduino Uno sending serial data. Shows how to log the data to a csv file that will open directly into Excel for graphing. How to log Arduino serial data to csv file (for. Receiver Code. The receiver will then receive the byte array from the other Arduino and interpret it there. Below is the code for the receiver. Note that this code is intended for a Mega since it will interpret the data received from the other Arduino and then print to the Serial Monitor what it received so that the user can check it. Psd codec download. Arduino - Strings. Strings are used to store text. They can be used to display text on an LCD or in the Arduino IDE Serial Monitor window. Strings are also useful for storing the user input. For example, the characters that a user types on a keypad connected to the Arduino. There are two types of strings in Arduino programming −.
So i build an 24x16 (hight of 16, length of 24) LED matrix and am using an Arduino Uno to control it. It is only a one color matrix and i am using an array to store all of the bits of data.
This is an example of how i am storing the data on the arduino:
The way that i store this data is by rows. ex: long frame [16] = {row 1 bits, row 2 bits, .. and so on}
If you convert 11184810 to binary; you would get 101010101010101010101010 which represents the data for one row of LED's.
One limitation that i came across on when using the arduino was the limited space on it to store theses arrays so i wanted to find a way to send it through serial.
I wanted to ask if i could get some help writing some code for Processing and for the arduino so that i could send this array data from Processing to the array on the arduino live over serial. I have never used Processing and don't know how to use it, but read that is is a good way of sending data to the arduino and also having a GUI to enter in the data.

The easiest way I can think of is sending the array with the values separated by commas.
GUI
First of all in my personal experience, making a GUI for user input in Processing is difficult, because you don't have predefined classes (as far as I know) to make text fields, check boxes, etcetera, so you would have to draw rectangles and program mouse and key events to change focus between fields. However, you could create a JFrame and Text Fields and everything, and still use Processing's serial communication, you would end up with a window running the sketch and an external window with your GUI. Here's some information about how to create frames and other elements. Remember that Processing is actually running on Java (sorry if that's not the correct term).
But if you are going to do that, you might as well switch to 'pure' Java
Sending data over serial
Processing
First you will need to build the array with your GUI, I have two ideas for that, either 16 fields, one for each row, where you write a number and it converts it to binary, or, making a group of checkboxes, 24x16, and each one represents a LED, so you tick the LEDs you want to turn on.
Arduino Serial Write Int Array
To send the data from Processing/Java to Arduino, here's an example code:
Where frame[] is the data you want to send to Arduino.
You have to import a special library to use serial communication. And create a class object (not sure if I'm using the correct term).

Then, on Arduino, inside loop() you use something like this:

Now data[] has the data you sent from Processing.
