Detailed Description
template<class T>
class LSM303D::RWRegister< T >
Read-write register class.
- Template Parameters:
-
T The underlying data type of the register. Provides an interface onto the writable registers of the LSM303D. Operator overloading means that it can be treated as a variable of type T for most purposes. Assignment from int is also explicitly supported to allow integer literals to be used without qualification or casting. The register value is cached on first read and updated on write, so read accesses do not use the I2C bus.
