Please help me with the calculation. I have been studying this write-up and explantin for the last 1 week and I believe I got it except that my calculation is coming wrong
Byte 6 is C23 = 1, C22 = 1, C21 = 1, C20 = 1, C13 = 0, C12 = 1, C11 = 1, C10 = 1 -> 11110111 You Have 00001000 [Like are reverse]
Byte 7 is C13 = 0, C12 = 1, C11 = 1, C10 = 1, C33 = 1, C32 = 0, C31 = 0, C30 = 0 -> 01111000 You Have 01110111
Byte 8 is C33 = 1, C32 = 0, C31 = 0, C30 = 0, C23 = 1, C22 = 1, C21 = 1, C20 = 1 -> 10001111 You Have 10001111
This 11110111 01111000 10001111 = F7788F You have 08778F
What am I missing or did not understand?
