Update Zephyr SDK # There is an active development community behind Zephyr OS. They frequently release updates and patch. We need to keep our own SDK instance updated with these releases.

I use the original
Arduino-UNO
and
Mega
for development. They are reliable and work a charm.
But for cost constrained projects, most of the times I have used Arduino clones.
It’s a common hassle these days with some Arduino clones having wrong boot-loader.
I wanted to have a permanent and repeatable way fix the boot-loader in Arduino boards.
Let’s look at how I did this in my favorite
Manjaro (Arch Linux)
In fact my
earlier article on installing AVRISP mkII on Windows 10
is one of the most
visited articles on this website.

After understanding the basics of how to do debugging on a Zephyr OS project,
let’s do something custom.
We would look at how to get started with Application Development on Zephyr OS.
This is Part 3 in the series of post on Zephyr OS. In Part 1 we saw how to setup the development environment on Manjaro (Arch Linux). In Part 2 we looked at how to create an Eclipse CDT IDE end project and then successfully debug our code.
Source code for basic-blinky
project is available at
https://github.com/boseji/zephyr-basic-blinky-stm32f3_disco
.
Source code for fancier-blinky
project is available at
https://github.com/boseji/zephyr-fancier-blinky-stm32f3_disco
. Note: This code is specific for STM32F3 Discovery
with PCB Revision C and above.

Let’s look at how to use
Serial-Port
under
Manjaro (Arch-Linux)
.
Our goal would be to flash a
ESP8266 chip
.
More specifically the tiny module
ESP-01
.
This may be out of time in the 2020.
I wanted to fix the serial-port issues once and for all.
Here goes my quest to simplify serial-port logging & debugging on Linux.

We are going to look at a example of Blinky running on
STM32F3DISCOVERY Board
.
Additionally we would be doing Debugging on the Zephyr OS. All this on the good ness of Manjaro (Arch Linux).
This is Part 2 in the series of post on Zephyr OS. In Part 1 we saw how to setup the development environment. In Part 3 we look at how to get started with Application Development
on Zephyr OS using our custom blinky projects on
STM32F3 Discovery Board
.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained and embedded systems: from simple embedded
environmental sensors and LED wearables to sophisticated embedded
controllers, smart watches, and IoT wireless applications.
From
Zephyr Project Documentation
We would look at initializing the environment and installing necessary dependencies.
This is Part 1 in the series of post on Zephyr OS.
In Part 2 we would look at
an Example of Blinky program running on
STM32F3DISCOVERY Board
. In Part 3 we look at how to get started with Application Development
on Zephyr OS using our custom blinky projects on
STM32F3 Discovery Board

Jupyter is great tool for Python development. It’s an open-source web application that
allows you to create and share documents that contain live code,
equations, visualizations and narrative text.
It’s used for data cleaning, scrapping and transformation, numerical simulation, statistical modeling,
data visualization, machine learning, and much more.
In-fact, I have already used it in some of my hardware projects.
Let’s Get this installed in our machines.
And have some fun !

It has been complicated to understand the cryptic number system of Nordic Semiconductor
development boards.
They don’t mention it clearly in their infocenter site also.
I decided, I had enough trouble loosing hair on this one.
Solving this mystery was imperative.

The TL866II Plus is a Parallel programmer.
Freqenty used in my lab for programming age old chips like AT89C51.
One might wonder what use I have for these old 8051.
Well I have big box full of these !
And many of my project still run 8051.
Yes!
All this time, Windows was the only way for this programmer.
Since, I am using Manjaro Linux wanted it to work there.
Lets look at how I mad this possible.
