Control AVR 8 bit Timer-Counter0 using AVR-GCC

Timers are an essential part of embedded systems. They make your life much more comfortable if used properly. Timers run independently to the main program flow so that they can do the job individually without disturbing precious calculations done by the CPU. You just set up the timer and let it run while your main program performs other tasks. Timers are easy to set up. In this post, an example is made for Atmega8 timers. Other AVR microcontroller models and even different brand chips have similar timers. Atmega8 has two 8-bit timers/counters and one 16-bit timer counter with many abilities. Standard 8-bit Timer/Counter0 features are: TCNT0 is an 8-bit timer counter register that keeps the current count number. The timer counter can be clocked by an external clock through pin T0 or from internal via pre-scaler. The timer counter increments (MAX value is 0xFF) and then restarts from BOTTOM=0x00. After the timer Overflows, the flag TOV0 is written to 1, and if TOIE0 bit in SREG is set, then timer overflow interrupt is executed. TOV0 acts as a ninth bit of counter register that is only set but not cleared. When this bit is combined with timer overflow interrupt –…

Why C instead ASM

ASM is a specific language, also referred as a low level programming language. It is a mnemonic to a machine code. It usually takes a long time to develop embedded programs in ASM language. Today even modern 8 bit microcontrollers are powerful and complex as they were a long time ago. The program memory of tiny chips reaches megabytes; they pack many peripherals and interfaces. Hardware code is becoming more complex; functionality grows up. This is one of the main reasons for using higher-level programming languages like C. By using C language you do not have to go into details how the processor works at the hardware level. You don’t have to think about hardware logic and how bytes are shifted between registers. It is better to leave to the compiler.

Tips to improve your electronic designs

Electronic designs cover a wide array of technical options. In this post, we will cover some of the basics that will help you improve your electronic designs and make sure that you complete it successfully. Block diagram The first part of your design schematic is a block diagram. Block diagram should be an extract from the document showing the hardware design. This particular section is similar to outlining an essay. This is because it gives the design an overview of the architecture, and the reader gets a reference. If you want your block diagram to look great, make sure that you include page numbers in the schematic sections. Naming the nets This can be a time-consuming process, but if you want to state the purpose of every net, you need to name them. Apart from this, naming the nets will help you in debugging the program and allow simulation runs. There might be many experts telling you that naming every net is not essential, but you should consider it while creating every schematic.

Eases Selling or Buying Notebooks

Students are buying the new textbooks from bookstores. There are different bookstores available in the local market and online platforms. Most of the students buy new textbooks, and after studies or semester-end, they sell these books in bookstores. The books-run website provides the college notebooks sell or buy a facility to the customers. The online website provides the best feature for the students and the best affordable price of the textbooks. They provide the book details with ISBN number such as book name, author name, and publisher. At the end of the semester, students can sell the books to the bookstores. But, sometimes, bookstores cannot pay the best prices for these textbooks. The online website provides the best prices for the students for their books. Most of the students involved the College notebook sell or buy process. There are different books for different semesters. All students purchase the textbooks at lower prices and sell these books after the exam to get some money. Some websites concerned in reselling the used textbooks have their own conditions and receiving these books. They have own shipping and pricing rules for reselling textbooks. Then, you can read all the guidance rules and follow all…

4 Reasons to Study STEM

The term STEM refers to an education that is focused on four specific areas. These areas of study are science, technology, engineering and mathematics. STEM education is supposed to help students uniquely learn these topics, focusing on interdisciplinary studies and applying the knowledge that has been learned. The interest in STEM has changed over time, but here are four reasons to study STEM. Job Opportunities When choosing a career, it is important to consider if there are jobs available in that particular field. In the case of the STEM subjects, this is not a worry. There are a wide variety of jobs available in these four fields. If a person is not interested in working in the STEM fields, specifically, the skills learned in STEM classes can be transferred to most other jobs. This includes skills like innovation and creativity, as well as other skills. Many jobs are STEM-related but are found in other fields.

How to Create Your Own Music Room

A music room in the home is a great addition that can be enjoyed by everyone, old and young. No matter whether you are a budding musician, an established musician, or want to have one in your household, creating that space for playing your favorite instruments is a great project to start. When designing your music room, a lot will ride on the types of instruments you will have in there. Perhaps you are thinking of filling your entire home with soothing classical piano tunes. Whatever the music style you are going for, there is the element of design to consider before you make a space wholly dedicated to sound. When putting together, your music room should work in harmony with the rest of your home in terms of ambiance and reduced noise levels, but still, be a room where you can gather your family and friends and jam!

A future Borg race? Just how far will wearables go?

Star Trek has been credited with predicting various technologies with startling accuracy. Warp drive and transportation beams might still be beyond us, but watch the way the Enterprise’s crew interact with the computer, and you will see marked similarities with any householder telling Alexa to switch on some music or put corn flakes on the shopping list. Furthermore, many have suggested that the latest advances in 3D printing point to a future when the replicators by which crew members order synthetic food and drink that looks and tastes no different from the real thing could one day become a reality. However, surely the weird and wonderful alien races from the world’s favourite science fiction series are purely the result of vivid imagination and fantasy. However, according to some, the future of humanity might bear more than a passing resemblance to one of the series’ most feared creations.
