combining bytes and doing math or bit shifting?

WebDescription. Shifts in a byte of data one bit at a time. Starts from either the most (i.e. the leftmost) or least (rightmost) significant bit. For each bit, the clock pin is pulled high, the next bit is read from the data line, and then the clock pin is taken low.

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 ... 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). diary of a christmas elf age rangeWebMay 6, 2024 · in this case MSB/LSB refer to 8-bit bytes. The datasheet indicates 7:0 LSB or bit 7-bit 0 is Least significant byte. the following is correct to combine 2 bytes into a 16-bit value. msblsb = (int16_t) (msb << 8 lsb); so if the LSB is 0x12 and the MSB 0x34, the 16-it value is 0x3412. pcbbc May 3, 2024, 4:05pm 3. cities in utah that start with f

"WebJan 15, 2014 · Since the STM32 is a 32-bit processor, the int type takes up 32 bits instead of 16, like on Arduino’s 16-bit microcontroller. This means that you can shift left, like x << y, with bigger values of y on the Maple before ones in x start to get shifted out. To calculate the number of bits of an integer type on the Maple, multiply its size in ... " - Bit shifting arduino
