We are trying to reveres engineer the Mitsubishi Electric Air con remote to switch ON and OFF from Arduino IR.
Followd the Chris as descried below. http://wiki.crowe.co.nz/Mitsubishi%20Heat%20Pump.ashx
(Except the decode bit pattern on C# because we do not want all settings..just on /off).
So,we got the binary bit pattern. (89 bits 0 and 1 patern). On the bit pattern we do not know the timing of High(1) and Low (0) singal.
So, we tried , X-SAT / NEC protocol timing ( for example 550 micor second ON /1100 micro second OFF) for Sending . But NOT working even we match binary bit pattern of Mitsu remote.
1. Is the carrier frequency of Mitsub is 38 KHz ?
2. we have plan to find the original timing with Oscilloscope for ON /OFF
Any clue how to proceed ? or Suggestion or Question?
