How to initialize (or Declare) a multidimensional array - Arduino …
Feb 22, 2014 · I consider it a bit of a shortcoming of the Reference section on the website in that it doesn't expand upon the Array section on how to declare a multidimensional array. Worse yet, after spending nearly two hours going through forum posts, it isn't well explained there either. (There are a couple of hints, though) Rather than leave it …

Declaring an multidimensional array of strings - Arduino Forum
Oct 14, 2020 · Serial.println(array[1][1]); // prints "array = mno521" void loop() Thanks this worked and I only had to slightly change the rest of the code to accommodate char vs String.
How to make two dimensional array - Arduino Forum
Oct 29, 2014 · In C strings are array of characters, which means the first declaration is going to create a 2 dimensions array where each position will contain an array of characters... this is equivalent to a 3 dimensions array of character. More precisely, each "position" (element) of the 2-dim array will contain a pointer to a character (char *).
Two-dimensional arrays - Programming Questions - Arduino Forum
Nov 19, 2021 · Look at that as 13 arrays of 8 elements each. To get the 3rd element of the 6th array you would use: element = array1[5][2]; // arrays are numbered from 0 EDIT: As pointed out by @runaway_pancake the above should be. element = array1[6][3]; // arrays are numbered from 0 to be consistent with the array and element numbering from the xero-eth.
printing data out in a 2d array - Arduino Forum
Sep 20, 2019 · i am trying to see if I can output serial data in a 2d arrray. I already made a function which was able to print out single bytes, but it had trouble with a string of bytes. In the forum i found an topic from Robin2 about how to serial print a string of bytes and I tried to implement it, but i dont get the result i expect to have. I tried at first with this code void printArray ( …
Finding the size of multi dimensional array? - Arduino Forum
Jul 4, 2016 · Thanks guys, MarkT: The idiom is: sizeof (array) / sizeof (array[0]) That gives you the outermost dimension, just index into this for the next level and use the same technique.
2d array to 1d array conversion - Arduino Forum
Nov 28, 2012 · I'm trying to pass the information of a 2d array to a 1d array like this. Which 2D array are you trying to pass to a 1D array? You have a several arrays of characters and an array of pointers. All the arrays are 1D. listbuffer = liste[x]; listbuffer is an array. You can't assign a pointer to an array. There is a strcpy() function to copy NULL ...
Pass 2D array to function - Arduino Forum
Oct 8, 2011 · In your example, you have defined that the argument is a one dimensional array, but you are trying to pass it a 2 dimensional array. As defined now, the character array does not contain strings (NULL-terminated arrays of characters). Is this intentional? Why are you passing character representations of values to the function, instead of values?

May 18, 2015 · Hello world of Arduino! I am relatively new to Arduino, but am an old crusty curmudgeon with a background in programming. I have been out of the coding game for awhile and seemed to be stumped by what should be simple. I am usually pretty self-sufficient in finding the solutions and have gone through a number of threads about this topic, but all seem to only contain bits and pieces, and I cant ...
