Fortunately, Arduino has built-in functions that make our lives much easier: This is helpful when we would like to convert a signed (i.e. representing positive and negative numbers) integer into tow bytes (using the two's complement method introduced in the last workshop) 鈥 for example ...
Here is a function that uses the code shown earlier to print a 16-bit integer to the serial port: // function to send the given integer value to the serial port void sendBinary(int value) { // send the two bytes that comprise a two-byte (16-bit) integer Serial.write(lowByte(value...
The first value is the data type (0=byte, 1=16 bit int,2=32 bit int,3 = float). The second parameter is the position in EEPROM, the value is stored. The third parameter is the current value. The rest of the line is a short description of the parameter....
8), HEX); //Serial.println(); // Convert the data to actual temperature // because the result is a 16 bit signed integer, it should // be stored to an "int16_t" type, which is always 16 bits // even when compiled on a 32 bit...
