Using nibbles (4 bits variables) in windows C/C++
2009年5月14日 · bool anotherBool : 1; unsigned int highestNibble : 4; }; The : 4 indicates that entry should occupy 4 bits. You can use any number of bits you like. You can use any built in type you like. Typically you end up casting a pointer to your data to a Header * then doing something like: pHeader->lowestNibble = 5;
Python split byte into high & low nibbles - Stack Overflow
2017年3月20日 · If you wanted to get the high and low nibble of a byte. In other words split the 8-bits into 4-bits. Considering the data string is a string of bytes as hexadecimals, then you could simply do:
Reading/Writing Nibbles (without bit fields) in C/C++
2010年6月24日 · 6. You may want to put this inside macros. If you're updating an existing value, you need to clear the nibble in byte before orring in the new value. byte = (byte & ~0xF) | (nibble1 & 0xF), and similarly for the top nibble. There are a couple of mistakes in the above code - you need a ~ in front of the byte masks.
.net - How can you nibble (nybble) bytes in C#? - Stack Overflow
Output: 2 bytes, each storing a nibble, meaning the 4 leftmost bits (aka high nibble) are 0000 while the 4 rightmost bits (low nibble) contain the separated nibble. byte x = 0x12; //hexadecimal notation for decimal 18 or binary 0001 0010 byte highNibble = (byte)(x >> 4 & 0xF); // = 0000 0001 byte lowNibble = (byte)(x & 0xF); // = 0000 0010
c - how to replace given nibbles with another set of nibbles in an ...
2016年12月23日 · Nibble has 4 bits, and according to your indexing scheme, the zeroth nibble is represented by least significant bits at positions 0-3, the first nibble is represented by least significant bits at positions 4-7, and so on. Simply shift the values the necessary amount. This will set the nibble at position set by the variable index:
