Detailed Description

Represents a 16-bit value as a byte. Useful for I/O.

Often we need to deal internally with values that fit in 16-bits but do not require much accuracy. E.g. table axes in RPM. For these values we can save storage space (EEPROM) by scaling to/from 8-bits using a fixed divisor.

Constructor & Destructor Documentation

◆ int16_byte()

constexpr int16_byte::int16_byte ( uint8_t factor )

inlineconstexpr

Construct.

Parameters

factor	The factor to multiply when converting `byte` to `int16_t`
divider	The factor to divide by when converting `int16_t` to `byte`

divider could be computed from factor, but including it as a parameter allows callers to create factor instances at compile time.
