Searching for a document - about how HALs can be made generally

Other Parts Discussed in Thread: CONTROLSUITE

Hello,

I am a newbie to C2000-Microcontrollers. So that is why a view weeks ago I was searching for a C2000-HAL privided from TI. And I think at that point I did not know about the controlSuite provided.

What I found was a document from TI about HAL more generally. It compares HALs made by the classical #define-way and HALs providing functions for controlling the microcontroller-hardware.

Now I am searching for this peace of document again, which I find very interesting. But so far I could not find it.

Does anybody know the name of the document or where I can get it?

Or can anybody recommend me any other document about how HALs could be made?


Thank you very much in advance!

    Don,

    You're probably thinking of the app note SPRAA85, which can be found here:

    www.ti.com/lit/an/spraa85d/spraa85d.pdf

    That document describes a very low-level sort of HAL, which only abstracts away the memory address of the peripheral registers. It's intended to make code portable across different C2000 MCUs. There are also higher-level HALs, which are designed to make code portable across different architectures. These are more like an API, in that they use a generic function interface whose implementation is hardware-dependent.

    Thank you Adam!


    Could you please also refer to such a higher-level API-like HAL?


    How about the USB-HAL provided for MSP430? How would you classify such an API for example?

    Thanks again, Adam!
