LED Matrix Editor - is online tool for editing and creating animations for 8x8 LED matrices. LED Dot matrix driven by MAX7219 works perfect with Arduino. Matrix as a 64-bit long integer. State of the 8x8 matrix can be presented as an unsigned long integer (uint64_t). In this case the code is pretty compact. Like this code for Arduino:
How to convert integer to string and string to int on
The Arduino programming language Reference, organized into Functions, Variable and Integer constants are numbers that are used directly in a sketch, like 123. Valid characters are 0 through 9 and letters A through F; A has the value 10, B is 11, up to F, which is 15. Hex values are indicated by the prefix . Note that A-F may be
Converting from hex to ascii to int? - AVR Freaks
/28/2014The HEX is only a way to show the value to a Human been. I know that maybe is hard to understand, but in computers (and Arduino is a computer) all the information is stored in binary form. HEX is only a way to show binary (as well as DEC).
Arduino: why does Serialprintln(int, HEX) display 4 bytes
The Arduino programming language Reference, organized into Functions, Variable and Constant, On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1). LANGUAGE Integer Constants. LANGUAGE String()
Arduino/C Convert a HEX String to a Decimal?
When Serial data is transmitted to an Arduino, it is sent one byte at a time. Even though you might type “123” in the Serial Monitor, that’s not quite what is sent.

x - Arduino hexadecimal string to unsigned long int
Learn Arduino, Lesson 3. RGB LEDs. If you have done any Internet programming, you will probably be aware that colors are often represented as a 'hex' number.
Convert a hex serial output into a normal integer
Routines are presented for displaying positive integers in binary and hexadecimal with specified fixed widths. This arose from some frustration in looking at the various ATMega registers using the Serial. print to display in either binary or hexadecimal format where leading zeros are suppressed. Arduino // // Prints a positive integer in
