12.2.1 Hardware Functional Abstraction Layer (HFAL)
12.1 Architecture
12.2 MPT612 software modules
This module consists of two sub modules: Hardware Functional Abstraction Layer
(HFAL) and MPPTCore. Both these sub modules are delivered as software libraries
together with the MPT612 IC. It is mandatory to use these modules to access the
MPT612’s MPPT functionality.
This module contains the functional abstraction of different peripherals that are of interest
to the application layer as well as different modules of MPT612 software. This layer
contains mini kernel functionality such as implementations of a round-robin scheduler,
task creation and software timers. These functions are useful during development of
applications based on the MPT612.
A range of different peripherals used in the application, such as PWM, Interrupts,
software timers, GPIO, UART and Flash can be accessed using this module. In addition,
utilities for logging the data onto the flash and printing the messages onto the console
screen are accessed from this layer.
