Hey guys, I need an array of length: 8192 storing data between -32768 and 32767 (2^16-1 range, equivalent to two bytes) after looking at the supported maple types, there seems to be no form of 2 byte data type and storing these values as ints consumes too much data, around 32.8kb! If I could store each value as a two bytes rather than 4, this would halve right?
Therefore, how can I do so?
Cheers,
Harris

pyrohaz - It might be worth noting for future reference that you could get the compiler to help.
void loop() {
struct { char a, b; } twochar;
// print the size of each type:
SerialUSB.print("sizeof(int) "); SerialUSB.println(sizeof(int));
SerialUSB.print("sizeof(char) "); SerialUSB.println(sizeof(char));
SerialUSB.print("sizeof(long) "); SerialUSB.println(sizeof(long));
SerialUSB.print("sizeof(long long) "); SerialUSB.println(sizeof(long long)); // !
SerialUSB.print("sizeof(short) "); SerialUSB.println(sizeof(short));
SerialUSB.print("sizeof(float) "); SerialUSB.println(sizeof(float));
SerialUSB.print("sizeof(double) "); SerialUSB.println(sizeof(double));
SerialUSB.print("sizeof(twochar) "); SerialUSB.println(sizeof(twochar));
