Radio modem based on CC1310

01.03.2016

Texas Instruments has released new software for the CC1310 that turns the chip into a complete radio modem controlled by AT commands. The CC1310 system on a chip consists of a Cortex-M3 microcontroller and a Sub1GHz radio, which allows you to create complete devices with wireless data transmission on a chip. However, in many cases it is required to add a radio channel to an already existing system with its own microcontroller. The new firmware (firmware) allows to solve this problem in a short time and with a minimum of engineering effort.

The rfEasyLinkNp software turns the CC1310 into a network processor, ie. into a microchip that completely takes care of all the tasks associated with wireless data transmission. At the same time, the system designer does not need to dive into the internal structure of the CC1310, packet formation features, modulation parameters, etc. This approach is often used by radio module manufacturers.

To add a wireless protocol, just read the description of a dozen AT commands. For example, to receive data, the main system controller sends the AT+RX command to the network processor , which in turn outputs the received data to the UART.

The network processor can do address broadcasting and has message filtering when receiving, which allows you to organize a "Star" network of hundreds and even thousands of devices in the 868 MHz band.

The unique feature of rfEasyLinkNp software is its completely open source code. This allows the advanced developer to add new AT commands or modify existing ones. Additionally, the network processor contains commands to generate a continuous carrier and send packets for transmission error testing, which will be extremely useful when testing devices in the production process.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Controlling objects using air currents 04.05.2024

The development of robotics continues to open up new prospects for us in the field of automation and control of various objects. Recently, Finnish scientists presented an innovative approach to controlling humanoid robots using air currents. This method promises to revolutionize the way objects are manipulated and open new horizons in the field of robotics. The idea of controlling objects using air currents is not new, but until recently, implementing such concepts remained a challenge. Finnish researchers have developed an innovative method that allows robots to manipulate objects using special air jets as "air fingers". The air flow control algorithm, developed by a team of specialists, is based on a thorough study of the movement of objects in the air flow. The air jet control system, carried out using special motors, allows you to direct objects without resorting to physical ... >>

Purebred dogs get sick no more often than purebred dogs 03.05.2024

Caring for the health of our pets is an important aspect of the life of every dog owner. However, there is a common assumption that purebred dogs are more susceptible to diseases compared to mixed dogs. New research led by researchers at the Texas School of Veterinary Medicine and Biomedical Sciences brings new perspective to this question. A study conducted by the Dog Aging Project (DAP) of more than 27 companion dogs found that purebred and mixed dogs were generally equally likely to experience various diseases. Although some breeds may be more susceptible to certain diseases, the overall diagnosis rate is virtually the same between both groups. The Dog Aging Project's chief veterinarian, Dr. Keith Creevy, notes that there are several well-known diseases that are more common in certain breeds of dogs, which supports the notion that purebred dogs are more susceptible to disease. ... >>

GPS and batter to fight potholes 05.11.2012

Two novelties for combating potholes on the roads are proposed in the USA.

A company in Boston is building an information network that, without human intervention, marks road irregularities on a map of the city. It uses the fact that many drivers have smartphones that have GPS and accelerometers. The phone with the appropriate program loaded on it, being in the driver's pocket, feels the bumps in the road, using GPS immediately notes exactly where it felt the shaking, and sends this information to the Internet on a map of Boston. Knowing where the potholes are, they can be patched.

A group of students at the University of Cleveland have developed a dry mix for temporary road repairs that, when diluted with water, forms a kind of batter. It has the properties of a so-called non-Newtonian fluid: with a slow impact or without any impact on it, it flows almost like water, and with a sharp impact, it behaves like a solid body. If you fill a pothole with this mixture, it quickly flows into all corners of the recess. When a wheel of a speeding car runs over a road defect filled with such material, under its impact the “dough” instantly hardens, turning out to be no weaker than ordinary asphalt. The exact composition of the substance will still be patented, so the authors are silent about it. The mixture withstands frost and road salt, is microbially degradable and environmentally friendly.
