bitsNbytesManup:

This is a collection of bitwise manipulation functions I developed myself for interfacing Analog-to-Digital Converters to microcontrollers and embedded devices. It can contactenate 2, 3 and 4 bytes together to form one integer number, be aware of your system/compiler support of the integer size (16 or 32 bits) otherwise ByteCat3() and ByteCat4() functions won't work properly.

Latest changes (June, 2017): Optimized byte concatenation and integer splitting functions to eliminate any possible memory leaks and increase execution speed.

List of APIs:

• unsigned int ByteCat2(unsigned char lowByte, unsigned char highByte);

This function contatenate 2 bytes and returns the output in an unsigned int.

• unsigned int ByteCat3(unsigned char lowByte, unsigned char middleByte, unsigned char highByte);

This function contatenate 3 bytes and returns the output in an unsigned int.

• unsigned int ByteCat4(unsigned char Byte0, unsigned char Byte1, unsigned char Byte2, unsigned char Byte3);

This function contatenate 4 bytes and returns the output in an unsigned int, Byte0 is the least significant byte and Byte 3 is the most significant byte.

• bool CheckBit(unsigned int number, unsigned int position);

Check is a specific bit if it is 0 or 1.

• unsigned int SetBit(unsigned int number, unsigned int position);

Sets a specific bit of a number to 1.

• unsigned int ResetBit(unsigned int number, unsigned int position);

Resets a specific bit of a number to 0.

• unsigned int TwoComplement(unsigned int number, unsigned int SizeInBits);

Returns the 2's complement of a number.

• void SplitInt16(int num, unsigned char *Buffer);

Splits 16-bit integer number into two unsigned characters (two bytes).

• void SplitInt32(int num, unsigned char *Buffer);

Splits 32-bit integer number into four unsigned characters (four bytes).

Feel free to contact me if any of the APIs isn't working properly.
