"Day 5 of the 100-Day Challenge! Today, let's dive into the world of bit manipulations, a cornerstone of embedded systems programming! 💻⚙️
In embedded systems, where every byte of memory and cycle of processing power matters, mastering bit manipulations opens up a world of efficiency and optimization.
Here are some key bit manipulation techniques tailored for embedded systems:
1.Set a Bit: To set a specific bit in a binary number, you can use the bitwise OR operator (|) with a bitmask that has a 1 in the position of the bit you want to set. For example, to set the 3rd bit (counting from 0) of a variable x, you would do:
x |= (1 << 3);
2.Get a Bit: To retrieve the value of a specific bit in a binary number, you can use the bitwise AND operator (&) with a bitmask that has a 1 in the position of the bit you want to get. For example, to get the value of the 2nd bit of a variable y, you would do:
int bit_value = (y >> 2) & 1;
3.Toggle a Bit: To toggle (invert) a specific bit in a binary number, you can use the bitwise XOR operator (^) with a bitmask that has a 1 in the position of the bit you want to toggle. For example, to toggle the 4th bit of a variable z, you would do:
z ^= (1 << 4);
4.Clear a Bit: To clear (reset) a specific bit in a binary number, you can use the bitwise AND operator (&) with a bitmask that has a 0 in the position of the bit you want to clear. For example, to clear the 1st bit of a variable w, you would do:
w &= ~(1 << 1);
