1.1. Before You Start
Before you start you need to:
Install the latest Smartsnippets Studio
Download the latest SDK for the DA1469x platforms
These can be downloaded from the DA1469x product page.
Additionally, for this tutorial a Pro Development kit is required.
The key goals of this tutorial are to:
Provide a basic understanding of Adapters concept
Explain the different settings of Flash Adapters
Give a complete sample project demonstrating the usage of Flash Adapters
1.2. Adapters Concept
The DA1469x family of devices supports several peripherals on different interfaces. To support them, the DA1469x SDK provides Low Level Drivers (LLDs) as well as adapters for each of the available peripherals. Both of these elements add an abstraction layer on top of the hardware functions, allowing a more intuitive approach for using the hardware peripheral. This makes software porting easier.
Low Level Drivers (LLDs)
Provide simple HW abstraction (register addresses, access functions, and so on)
Are not aware of Operating System (OS)
Add zero overhead to the application
Avoid race conditions when using HW
OS based applications consist of more than one task
Two or more tasks might need the same resources
Adapters make sure access to the resources is managed
Adapters are not implemented as separate tasks and should be considered as an additional layer between the application and the LLDs. It is recommended to use adapters for accessing a hardware block.
