Re: Reverse engineering Sanyo AC rcs-3pss4e remote

Thanks for your help and time in finding the solution to this problem ! I’ve tried to verify your logic but I can’t reconstruct the checksum. What I did : I made the sum of the nibbles of bytes 3->14 (in LSB8) = 24 nibbles and added 0x04 (or 4 in decimals) but the result of this sum is never equal t...

Reverse engineering Sanyo AC rcs-3pss4e remote

Hi everybody, I try to reverse engineer the Sanyo AC rcs-3pss4e remote. This is a 152-bit protocol (sanyo 152AC). I was able to figure out the meaning of all bits except the last byte and bit 57 (bit 1 of byte 8). I suppose the last byte is the checksum. Unfortunately, I cannot find the key to calcu...

This is what I found in the help documentation of AnalysIR : “LSB8 takes the MSB format hex value and turns each 8 bit byte of the overall HEX value into LSB. For example, the MSB HEX (Bina...
