Have you ever tried to learn about ARM Cortex M3/M4 Processor by reading a book or technical manuals and found stuck ? . Have you ended up seeing bits and pieces all over the map but could not able tie it all together to have a big picture ?
This course is for Embedded Engineers/Students like you who want to learn and Program ARM Cortex M3/M4 based controllers by digging deep into its internals and programming aspects.
Don't worry if you are new to ARM based controller. In this course, you'll see everything you needed to quickly get started with Programming Cortex M3/M4 based controller. The lab session covers various programming assignments which helps you to remember the concepts better.
Listen !! Its not Mandatory to have a Hardware !
Many people ask me which hardware to buy, i would like to mention that
if you buy new hardware for every new course then the problem never ends. The biggest objective of this course to understand the core internal details with register level programming and to share generic ideas to handle interrupts and peripherals so that you can confident enough to handle any development board based on any microcontroller.
You will get a full coverage of ARM Cortex M3/M4 processor with full hands on lab sessions. Once you complete the course, I assure you that you will be confident to handle any microcontroller in terms of writing firmware, Memory maps, handling interrupts,Nested Vector interrupt controller(NVIC) , Writing IRQ handlers, handling system exceptions and many more. I even walk you through reference manuals and datasheets to understand things better.
For the lab STM32F4xx based Discovery board is used. But the Course is designed such a way that it can be applied to any Microcontroller based on ARM Cortex M3/M4. So, need not to buy any special hardware for this course. if you already have some other development board i would suggest you keep using that. You can download the source code and play with your own hardware.
Save time and have fun !
Watching lectures, Programming assignments and lots of animations will save hours off your self-study time, and will give you the confidence to look at embedded processors from a different perspective. So, learn something new this year and boost your momentum at work .
My promise !
I am confident that this course will save you many, many hours of studying/experimenting/googling time to learn about this processor. I will personally answer your questions about this material, either privately or in a group discussion. If you are in any way not satisfied, for any reason, you can get a full refund from Udemy within 30 days. No questions asked. But I am confident you won't need to. I stand behind this course 100% and am committed to helping you .
ARM Cortex M3, ARM Cortex M4, Embedded Programming, ARM, RTOS,FREERTOS
In this lecture you will understand how to switch between different access level by using the Processor CONTROL register
In this lecture you will understand
In this lecture you will understand
In this lecture i will walk you through steps, which happens once you reset the processor.
Understanding processor reset sequence is very important to handle Embedded processors more efficiently if you are involved in a project like developing boot loaders or RTOS
So, you know that Processor registers and Special Purpose registers are not memory mapped. How do you access these registers in a C program when they are not memory mapped ??
In this lecture i will you will learn how to install newer KEIL-MDK-5 software for your embedded software development
After downloading the KEIL-MDK-5 software , its very important to install the software pack corresponding to your board. In this lecture you will learn how to locate your board through pack installer and install the software pack related to your board !
In this lecture I will walk you through step by step procedure to
In this lecture I will introduce various debugging features available in the KEIL Micro Vision software
In this lecture lets explore the different components of the STM32F4 discovery board which we will be using in our lab sessions
In this lecture I will take you through the Reference manual of the MCU to understand
1) HSE(High Speed External Clock)
2) HSI ( High Speed Internal Clock)
3) PLL (Phase Locked Loop) ( used to boost the clock in the MCU )
So, you got the new board ?
I will show you , how to quicky test your board with out coding anything
In this Lab session We will code to understand
In this Lab session video , lets explore
In this lecture , I will explain
In this lecture lets dive in to MCU data sheet to explore
In this lecture I will explain
In this lab session video , we will code and understand how to access the individual bits of the memory address using bit addressable capability of the processor
In this Lecture I will Discuss about the STACK and why it is used
In this lecture I will discuss about the
1) Stack model of the processor (Full Descending )
2) How to initialize the MSP to valid stack base address via vector table
3) Initial stack init
In this lecture I will talk about the rules of the ARM-THUMB Procedure call standard
In this lecture, you will learn
1) Stacking and Un-stacking sequences in the processor when the exception occurs
2) Stack frame and many more
3) Interactive animation
In this lab session video, we will learn how to use MSP and PSP for stacking and unstacking operation
In this lecture you will learn,
1) What are exceptions, different types of system exception and interrupts
2) Intro to priority and many more
In this lecture you will learn about
1) Nested Vector Interrupt controller and its uses
2) How system exceptions and interrupts are connected to processor via NVIC
3) What is the meaning of IRQ number and how it is related to interrupts
4) Various key points related to NVIC, interrupts and IRQs
I will demystify the interrupt priority in this lecture by taking you through couple of case studies
1) With various interactive animations and pictures it will be clearer and easier to understand how interrupt works with the priority
2) You will also learn interrupt grouping, pre-empt priority and sub priority with case studies
In this lecture you will learn about
1) How to activate and de-active interrupts and system exceptions globally in the processor
2) you will come to know how to handle registers like PRIMASK,FAULTMASK,BASEPRI to mange the interrupts and system exceptions globally
3) Respective CMSIS related APIs and many more
There are lots of registers NVIC provides to manage and handle the interrupts and system exceptions
Those registers are discussed one by one in this lecture.
By doing this lab experiment you will understand
1) How to Enable/Disable the global interrupts using global interrupt management registers
2) plying with BASEPRI,PRIMASK registers to enable/disable as per the priority level of the interrupt
3) You will also come to know , how to setup the priority level for an interrupt
Do you know that to debug embedded firmware, signals, protocols you dont need a bulky and expensive CROs or logic analyzer machines
What you just need is a USB logic analyzer which i explained in this lecture.
By using this hardware, you can quickly able to debug most of the problems which occur in the embedded firmware development
So, lets debug the code in smart way, instead of just staring at the code
I will show you how to use USB logic analyzer tool by using dedicated software
This is a interesting experiment where we will test the interrupt nesting and pre-emption
We will configure 2 different exceptions 1) systick timer exception and 2) button interrupt
Configuring different priorities to different exceptions and observe the effect of them in LOGIC analyzer software while they occur
Inverting the priorities and observing the effect
Practically testing the pre-emption between exceptions on the LOGIC analyzer software
and believe me you will learn lots of other key points .
In this lecture you will learn about various activities which take place once the peripheral issues the interrupt
I will also discuss various registers which are going to get affected once there is an interrupt assertion
Also we will discuss the case of single pended and double pended interrupt
In this lecture I will walk you through exception vector table and its importance during interrupt
you will also come to how to relocate the vector table using VTOR register of the NVIC
We will also discuss the case study fro relocating the vector table
