System Wide control APIs

[elsalahy]

Summary:

We need to have a system wide control APIs that allow us to

• Initialize the system clock
• Initialize the system debug interfaces
• Initialize relevant sensors
• Handle multiple error levels based on the severity of the error.

Why do we need this?

To avoid code replication and follow the DRY principle in the application development.

What is already there? What do you see now?

BSP & HAL control of the device components.

What is missing? What do you want to see?

High level APIs that initialize the system based on a set of configurations passed from application layer.

How do you propose to implement this?

Handle each component separately and define and implement the affiliate functions:

• System Initialization
• System Erros
• System Debugging

Environment:

Baremetal

Acceptance Criteria:

• All Applications compile and function as intended before the new system wide changes.

What can you do yourself and what do you need help with? ALL

Sensor on board components HAL is covered as part of #73

For the current status of the APIs and new names:

• Clock Function would be something like GNSE_BSP_CLK_Init, with the content being the configuration present currently in all applications.
• Debug interface name would be GNSE_BSP_DBG_Init. Like with the clocks, all applications currently redefine DBG_Init without any changes between them.
• Sensors are already done in #73, as was mentioned previously
• Error levels were sort of updated with #159 with the verbosity being configurable with simple function calls. Low verbosity could still be added to this.

Ok some notes:

• For the clock it should be GNSE_HAL and not GNSE_BSP
• DBG_Init() will be handled by the LPM since it relates to using the debugger in low power

This issue is implemented in #73, #171 and #207 For further improvements we should open new smaller issues.
