Websimply we have used left shift operator (<<) and right shift operator (>>) to move the bits num&0X0F gives the last nibble and num&0XF0 gives the first nibble. Output: Last Nibble: 0100 First Nibble: 1100000 Swapped bits: 01000110 New number: 70 We hope that this gives you a better understanding to swap the nibbles in the byte in Python. Thank you. Web06. maj 2024. · swap is a single cycle instruction on the atmega. there will be some additional code for moving a memory location into a register and then writing back, but that is also the case with the shifts. so the swap version is the fastest/smallest. not c portable though, but we are in the context of arduino here, aren't we?

Web1. In this C Program, we are reading the number using ‘n’ variable and also the bit positions using ‘p’ and ‘q’ variables respectively. 2. First shift the bit in given position to right-end. This can be achieved by the code below. for p’th bit – n & (1 << p)) >> p) for q’th bit – (n & (1 << q)) >> q) 3. Next step is to ... Web23. dec 2024. · To write the lowest nibble you'd want to do something like: dest = dest & 0xF0; // Clear all bits in the low nibble dest = dest new_nibble; // Set new bits in the low … ibei biblico theologica
