FreeRTOS tutorial on STM32

A High-density line of STM32 microcontrollers has quite a bunch of features that can be used in your programs. However, the more features you add to the source, the more complicated the program becomes, and it may become challenging to keep up with all things. Relying on the main loop and interrupts becomes a time-consuming task to manage. If you do not want to struggle while tuning things up manually, you can use one of the best free real-time operating systems (RTOS). It is handy when you need many separate functions to run in parallel without missing a task. RTOS scheduler takes care of giving each task a required period to perform. There are many great RTOS systems around. Many of them are free and open source. Follow the FreeRTOS tutorial to see how easy it is to run complex tasks. I love using FreeRTOS, which has a long successful history and is flexible to fit multiple types of hardware. You can check out my demo FreeRTOS tutorial on Atmega128. I also encourage you to give a try for other RTOS systems like ChibiOS, BeRTOS, and others. FreeRTOS is quite simple and easy to use. It has practically all of…

Flashing programs to STM32. Embedded Bootloader

Post updated with new screens and up-to-date information (2019)! There have been several requests from users to explain more about loading programs into the flash memory of STM32 microcontrollers. There are several ways on how to perform stm32 flash programming. You may enter the STM32 bootloader directly via USART interface and upload the binaries. The more advanced and flexible method is to use an ST-LINK utility – an ST-based adapter, which connects to STM32 board through JTAG interface. Many ST development boards already have this feature included. Otherwise, you can jump-wires from one to another, or get a dedicated portable ST-Link adapter. Also, you can use standard third-party JTAG tools such as J-Link. Finally, you can flash your bootloader that works with any interface (USART, USB, SPI, etc.) The STM32F103RB board Any of these methods are great if they get the job done. In this topic, let us focus on how to perform STM32 flashing by using a bootloader. Today probably, no manufacturer is producing developing boards with RS232 interface. Nevertheless, you like me, probably have a dozen older boards with a serial port. They are great boards still to use in many projects.

Effects of Thermal Conductivity on Soil

Thermal conductivity is the ability of soil to conduct heat, and thermo-mechanical analyzer is used to check the thermal conductivity of the soil. Thermal conductivity measurement proves helpful to judge the temperature of the ground in the fall, to have an idea of its temperature in a different season like summer or winter. You can buy special meters to check the thermal conductivity of the soil. If you want to design meters, check mjsdesigns.com to buy latest boards and chips. It plays a vital role to know about different aspects of microenvironment like vegetation, eating habits of animals, and microorganisms in the soil. Thermal conductivity is specifically crucial for agriculture to check the nature of the soil. It is essential to understand the properties of geothermal energy sources and to check the transferability of heat from one area at a given temperature incline. Seed Germination and Emergence Different types of seeds are used to grow different plants, but the time of development for each plant is based on the temperature of the soil. Thermal conductivity of soil effectively transfers the heat of the sun into the ground, and this transfer rate will determine the developmental process of seed. Prefer soil…

How to Start a Non-Emergency Medical Transportation Business

Right now, you must be aware of the several dynamic reasons why a non-emergency medical or elderly transportation business offers entrepreneurs such a great business structure. With the development in the health care sector and the surge of baby boomer retirees, this industry is big and ready to get even bigger now. In the following paragraphs, we look at the way to start your non-emergency medical transportation (NEMT) company. Know about a few of the steps that are required and a few of the facets of this particular business that you may have to consider. Independent or Franchise Operator? These days there are several people offering non-emergency medical franchises. Business people benefit from the business model while they can easily work under a recognized brand and get assistance and education to get going and operate a business. On the other hand, with the franchise costs that should be paid in the beginning and on a continuous basis, the upside potential for profit is usually reduced. In case you do your research, you’ll find that this particular business isn’t so complicated, and it’s easy to start up and flourish independently.

What makes the orthodontist treatments so important?

Even if we do not eat healthily, everyone still needs a healthy bite. Orthodontists are not only important for the oral, but physical health too since they make it easy for you to bite. They help you align your teeth and your jaw, make your mouth, and bite the way nature intended. These are available for all kinds of people since oral health is very important for everyone. While dentists are buying keeping your teeth healthy, orthodontists help you make your smiles and your bites better and help you stay healthy. If you are currently in Arizona, orthodontist queen creek is the one place that you can visit for immediate help. Are orthodontist treatments just cosmetic treatment? While a lot of people believe that these treatments are just about making your teeth look good, they help you also bite better and healthy. A good smile and alignment are, of course, a sign of good result and healthy teeth for the people viewing, but the person who received it can also notice the difference while chewing and eating. Food and nutrition are a very important role in the health of a person, and orthodontists play an even more important role in…

Building and installing USBASP-USB programmer of AVR microcontrollers

USBASP is well-known USB programmer for Atmel AVR microcontrollers initially supported by Thomas Fischl. USBasp flash uploader is made of an Atmega8 or Atmega88 and few other components including resistors, capacitors, LEDs, and connectors. The adapter works on a firmware driver, which gives a room for customization, and new chips updates. The USBasp programmer has been so famous for a long time. It has been supported by avrdude – an open source programming software, which runs on multiple platforms like Windows, Linux, or Mac. Since Arduino popularity has skyrocketed, the need for such tools has diminished, and so the support has been stopped. I can assure you, that USBasp still works and there is no problem to run it on Windows 10. USBasp circuit diagram Let us see what is this adapter is made off and how to set it up to run on Windows 10. You can find the original circuit in the author’s site: http://www.fischl.de/usbasp/. There you will also find several third-party PCB examples to choose. The core of USBasp adapter is Atmega8 (or Atmega88) microcontroller clocked with 12MHz crystal. The assembled PCB is ready to be connected via simple USB B type cable (PC side needs A…

How To Use Technology To Boost Your Business

Technology and business have always been closely intertwined. Technology can be used to streamline business processes, automate tasks, improve communication, improve the quality of the product, and much more.
