# File: FreeRTOS.py

# Author: Carl Allendorph

|
|
# Description:
|
|
# This file contains some python code that utilizes the GDB API
|
|
# to inspect information about the FreeRTOS internal state. The
|
|
# idea is to provide the user with the ability to inspect information
|
|
# about the tasks, queues, mutexs, etc.
