WebTo turn a bit on: data = 1 << bitNumber; The right-hand side ( 1 << bitNumber) is a bit-shift operation to create a suitable bit-mask. It takes the single '1' bit and moves it left until it reaches the desired position. The bitwise-or assignment ( =) combines that new bit-mask with the existing bits in data. This turns the desired bit on, but ...

WebDec 15, 2013 · For example, the bitwise AND of 10110111 and00001101 is 00000101. In a nutshell, “& 0xff” effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits. It’s seen most in cases like when trying to transform color values from a special format to standard RGB values (which is 8 bits long). WebJul 9, 2024 · if you have two bytes then it is a 16 bit number. in binary, if you look at the individual "bits" this is how it works. there are 8 on/off in a byte. if the first bit is true you add 1 to your result. if the second bit is true you add 2 to your result. if the third bit is true you add 4 to your result. if the fourth bit is true you add 8 to ... bulldog running into couchhttp://static.leaflabs.com/pub/leaflabs/maple-docs/0.0.12/lang/cpp/bitshift.html bulldog round tube gooseneck coupler
