Received Raw signal displayed in Serial Monitor is different from the sent raw IR signal

Hi!

I

I am trying to send back a RAW IR signal I got from a Panasonic AC Remote. Upon trying to the AC unit itself, it fails to control the unit. I created a simple receiver that displays the signal received in the serial monitor. On the monitor, the RAW data displayed is different from the one I sent. And an error message is displayed:

C:\Users\ACER\AppData\Local\Temp\arduino_modified_sketch_437114\SendRawDemo.ino: In function 'void loop()':
C:\Users\ACER\AppData\Local\Temp\arduino_modified_sketch_437114\SendRawDemo.ino:120:55: warning: large integer implicitly truncated to unsigned type [-Woverflow]

}

/*

  • NEC address=0xFB0C, command=0x18
  • This is data in byte format.
  • The uint8_t/byte elements contain the number of ticks in 50 us.
  • The uint16_t format contains the (number of ticks * 50) if generated by IRremote,
  • so the uint16_t format has exact the same resolution but requires double space.
  • With the uint16_t format, you are able to modify the timings to meet the standards,
  • e.g. use 560 (instead of 11 * 50) for NEC or use 432 for Panasonic. But in this cases,
  • you better use the timing generation functions e.g. sendNEC() directly.
