WebBecause only 6 bits are used for page_size_log, the left shift can not be greater than 63. This is fine on 64 bit architectures where a long is 64 bits. However, if a value greater than 31 is passed on a 32 bit architecture (where long is 32 bits) the shift will result in undefined behavior. This was generally not an issue as the result of the Web21 Oct 2015 · One way of fixing this is to split the 16-bit number before calling shiftOut. shiftOut (dataPin, clockPin, MSBFIRST, highByte (numberToDisplay)); shiftOut (dataPin, … iteriver
