Long to byte array help! (self. arduino) submitted 3 years ago * by swampyness [Solved] I'm only getting the integer returned. When you sum the bytes into anotherLongInt, they're each implicitly promoted to type int, which in arduino environment is 16 bits. Therefore, you can't even shift them 24 or 16 bits, and the compiler tells you this:

Convert int/short/long to bytes - C# C Sharp

Arduino does not have the split() function used in the Processing code in Recipe 4. 4, but the functionality can be implemented as shown in this recipe. The following code receives a message with three numeric fields separated by commas. For example, Arduino defines an int as two bytes, but Processing (Java) defines an int as four bytes
