OTA OS Functional Interface

The OTA OS Functional Interface definition.

OTA OS Functional Interface

The OTA OS Functional interface is a set of APIs that must be implemented for the device using the OTA library. The function implementations for this interface are provided to the OTA library in the user application. The OTA library calls the function implementations to perform functionalities that are typically provided by an operating system. This includes managing events, timers, and memory allocation. While these are typically provided by operating systems, an operating system is not required. Any implementation of these functionalities that meet the requirements of the interface will work.

The OTA OS Functional Interface is defined in ota_os_interface.h.

The functions that must be implemented are:

• OTA OS Functional Interface Initialize Event Mechanism
• OTA OS Functional Interface Send Event
• OTA OS Functional Interface Receive Event
• OTA OS Functional Interface Deinitialize Event
• OTA OS Functional Interface Timer Callback
• OTA OS Functional Interface Start Timer
• OTA OS Functional Interface Stop Timer
• OTA OS Functional Interface Delete Timer
• OTA OS Functional Interface Malloc
• OTA OS Functional Interface Free

An example implementation for the OTA OS Functional Interface for FreeRTOS can be found in the files ota_os_freertos.c and ota_os_freertos.h.

An example implementation for the OTA OS Functional Interface for POSIX can be found in the files ota_os_posix.c and ota_os_posix.h.
