Sending Large Strings of Data to Arduino 08 January 2012 on arduino. For one of my projects I needed to send between 200 and 500 bytes of data to my Arduino quickly over a serial connection. The problem I faced is that the Arduino only has a 128 byte read buffer.

Converting Integer to Character Arduino - instructablescom

Arduino makes it pretty easy to store use character strings, but those strings compete with your variables, so you can’t do as much. Here’s how to put big strings into read-only program memory and use them. Make sure p_buffer is large enough for the largest string. Then just wrap all your static strings in P(), Like this: Serial. print

I tried making an array double data[640][14], but the compiler says that the array size is too big. Maximum size of 2D array on Arduino Uno. Ask Question 0. I tried making an array double data[640][14] An Arduino Uno has an Atmel 328p MCU. It only has 2048 Bytes of memory. Considering a double takes 8 bytes (64bits) on its own. 640 * 14

Sending Large Strings of Data to Arduino - Andrei Ostanin

Displaying FLOAT variables in Arduino. It seems that the Arduino software doesn't have much support for displaying float variables, certainly the sprintf() function doesn't work. However there is a useful c function called dtostrf() which will convert a float to a char array so it can then be printed easily. The format is
