How to convert old MSB first 32 bit IR data codes to new LSB first 32 bit IR data codesFor the new decoders for NEC, Panasonic, Sony, Samsung and JVC, the result IrReceiver.decodedIRData.decodedRawData is now LSB-first, as the definition of these protocols suggests! To convert one ...
If the first character is the header, it then calls the function named readArduinoInt to read two bytes and transform them back into an integer by doing the complementary mathematical operation that was performed by Arduino to get the individual bits representing the digital pins. The six ...
