MSP430 Energy Measurement Library API Reference


The MSP430™ microcontroller (MCU) Energy Measurement (EM) software library provides the means to configure the Sigma Delta 24 (SD24 and SD24_B) in MSP430i2xx and MSP430F6xx devices to seamlessly implement Energy monitoring applications. The energy library supports several metrology functions to showcase best-in-class-performance when using Current Transformer (CT), Shunt sensors or Rogowski Coil.

The library also takes advantage of the Fixed Point Math library to compute the metrology parameters.
