I have an integer (1500). I have found its highByte and LowByte below and sent it from a Photon to another one using the code below.
//NUMBER = 1500 : LB = 220 HB = 5
byte high = highByte(1500); // = 5
byte low = lowByte(1500); // = 220
I am receiving the byte array on the other board correctly. What is the code for reconstituting the original value (1500)?
Thanks in advance for the help.
@Jimmie, and “integer” in Particle devices is expressed as a 4 byte/ 32bit value as opposed to the typical Arduino 2 byte / 16bit representation. For you highByte/lowByte to work, you will need to define a 16bit integer or using
short int. The target board needs to have the same representation. Then, to reconstitute your integer, you simply need to reconstruct the high and low bytes with:
short int value = highByte << 8 + lowByte; // the <<8 is a bit shift which is the same as a multiply by 256
