## README

# Files and dependincies 
This implementation of an RTOS is created for an STM32F429ZIx MCU to be specific,
## miro.c
includes all the RTOS functions defintions
## BSP.c
includes functions related to the specific board used which in this case was the STM32F429I-DISCOVERY board
## main.c
contains two simple threads , a thread that blinks the green led on the board and another thread that blinks the red led on the board
this is just a simple illustration example to show that the OS applies context switching between tasks based on thier priority 
tasks or threads created first by the OSthread_Sched() function implicitly have higher priorites than tasks created later on
## Header files
all header files just include function declarations and user defined data types
# NOTE
- the code is documented relatively well. in the future i will probably try to improve more on it by adding semaphores and synchornization between tasks but for now
  its a really good starting point for learning about RTOS in general

- All of this was done thanks to an excellent playlist by Quantum leaps on youtube it really goes into depths on how to implement your own RTOS

# Things i plan to do with this RTOS
- Port this RTOS to my microblaze MCU system on the Arty S7-25 FPGA board
- Hook that board up with a TFT LCD screen and a joystick and some switches
- Port space invaders game to my system
- if all goes well i will plan next to port DOOM to this system by following along the book by the name of  "Game Engine Black Book: Doom"
