Detailed Description

template<class T, unsigned int BitI, unsigned int Nbits>
struct microstrain::BitfieldMemberN< T, BitI, Nbits >

A class which represents part of a bitfield.

This is used to store the range of bits, to avoid repeating them in get/set function implementations and other situations.

Usage would typically be like this:

using Part1Bits = BitfieldMemberItoJ<uint16_t, 0, 12>;  // First 12 bits, holding a u16
using Part2Bits = BitfieldMemberItoJ<uint8_t, 12, 16>;  // Last 4 bits as a u8
 
uint16_t getPart1() const { return Part1Bits::get(m_value); }
uint16_t getPart2() const { return Part2Bits::get(m_value); }
void setPart1(uint16_t p1) { Part1Bits::set(m_value, p1); }
void setPart2(uint16_t p2) { Part2Bits::set(m_value, p2); }
 
uint16_t m_value;

Template Parameters

T	Type of the bitfield member. Must be integral or a non-scoped enum.
BitI	The 0-based index of the first bit used to represent this value.
Nbits	Number of bits in the field used to represent this value.
