internal working of the Microcontroller and its Peripherals.
Coding for the Peripherals STEP-BY-STEP and Developing
software
drivers entirely from scratch by extracting maximum
information
from Datasheets, Reference manuals, specs, etc Protocol
Decoding
Using logic analyzers, Debugging, Testing along with Hints and
Tips. Long Description: Learning Embedded System Programming
can
be a challenge. Since it's a relatively complex field, there's
no actual gold standard yet for how things are practiced, or
taught, which can frustrate people who are just trying to
learn
new things and couldn't connect the dots. This is the
motivation
behind creating this course to help engineers and students
learn
different aspects of embedded systems by providing high-
quality
advanced lectures at a relatively low price. Master Behind the
Scene working; created this course because I believe your time
is precious, and you shouldn't have to hunt around to get a
practical foundation In Embedded System Programming. In this
course, you will learn to write your peripheral driver for
most
commonly used peripherals such as GPIOs, I2C, SPI, USART,
etc.,
and the exciting thing is that you will learn everything from
scratch. No 3rd party libraries! No blind coding! Write your
driver APIs by dealing with the peripheral registers of the
MCU!
Code and Implement APIs from scratch, diving into the
datasheet
and reference manual of the MCU. I will thoroughly explain how
to extract the maximum information from datasheets, Technical
Reference manuals to configure and handle peripherals. These
techniques you can go and apply to any MCUs you have at your
hand. In this course, I will walk you through step-by-step
procedures on configuring various Peripherals like GPIOs, SPI,
USART, I2C by taking you into the reference manual and
datasheet. We will develop a fully working driver code,
interrupt handlers, sample application everything from scratch
to understand the big picture. In each lecture, I assure you
that you will learn something new to use in your work or
projects. You'll find yourself handling these peripherals with
much more clarity. You will be able to speculate and debug the
problem quickly. I'll show you tricks and tips to debug the
most
common issues using debugging tools such as logic analyzers.
This is not the Arduino style of programming: I believe
Arduino
is for quick prototyping of projects/products but not for
mastering the working of micro-controllers and their
peripherals. Unlike Arduino programming, where you develop a
quick solution and prototyping of products using third-party
libraries, this course is entirely different. In this course,
no
3rd party libraries are used. Everything we will code by
referring to the technical reference manual of the MCU and
will
create our own library. The Power of this approach is that you
can quickly speculate problems and debug like a pro when
things
go wrong in your project due to bugs. If one thing me and my
students are good at is "debugging,." To achieve good
debugging
skills, it's essential to code by understanding how things
work
behind the scene but not by blindly using some third-party
libraries, and that's the biggest TAKE away from this course.
The course is designed and explained so that it is generic
across any microcontroller. The code we develop can be used as
templates to quickly build a peripheral driver for your MCUs
on-
chip peripherals. Software/Hardware used: In this course, the
code is developed so that it can be ported to any MCU you have
at your hand. If you need any help porting these codes to
different MCUs, you can always reach out to me! The course is
strictly not bound to any 1 type of MCU. So, if you already
have
any Development board that runs with an ARM-Cortex M3/M4
processor, I recommend you continue using it. But if you don't
have any development boards, then check out the below
Development boards. 1. STM32F407xx based Discovery board (
This
is the board used in this course) MCU Vendor:
STMicroelectronics
IDE: STM32CUBEIDE (Free) My promise: I am confident that this
course will save you many hours of
studying/experimenting/googling time to learn about MCU
programming. I will personally answer your questions about
this
material, either privately or in a group discussion. If you
are
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. Learning order of FastBit Embedded Brain
