Connect Designs Quickly and Securely to the Cloud Using Amazon FreeRTOS

A traditional embedded systems developer normally works at the bare metal level on disconnected devices. Now with the IoT requiring systems to connect to the Internet, it means that embedded system developers need to learn how to connect their devices and use a higher level operating system, such as a real-time operating system (RTOS). Rather than starting from scratch and learning every nuance required to securely connect an embedded system to the Internet, developers can use Amazon FreeRTOS. Find out more . . .

Makers and Engineers: Get to Know Your Instrumentation Amplifier for Accurate IoT Data Capture

One of the major types of node for the IoT is for sensors. These are key to many applications where a variety of measurements need to be made for running a home or a production process. Sensing is where the Internet of Things (IoT) and the smart home begins, and it’s where DIYers, makers, and even professional designers run into their first problem. Many inexpensive transducers such as accelerometers, force sensors, strain gauges, and pressure transducers are designed around resistive Wheatstone bridges, so their outputs are differential voltages in the millivolt (mV) region.

A Simple Solution Simplifies Authentication to Ensure Device Security

Security is incredibly important for any IoT device. Poor security can enable hackers to access systems or take over even what may seem like harmless devices for their attacks. The ability to authenticate data or operations in a system is a fundamental requirement for security. For developers, implementing the detailed steps required for authentication can be challenging, particularly in resource constrained systems. Even when resources are available, time to market pressures and lack of awareness can result in shortcuts during development that can leave the final system compromised. Read more . . .

Use HyperBus to Expand Memory in Tiny IoT and Wearable Designs to Save Space and Cost

The Hyperbus can be used to provide some significant advantages for IoT devices. With IoT nodes and wearable devices shrinking, designers need to make maximum use of their microcontroller’s on-board memory to minimize board space, power, and cost. However, sometimes memory expansion cannot be avoided. Instead of defaulting to a 32-bit controller’s bus structure, designers should consider HyperBus, a high-speed, 333 Mbit/s, 8-bit, double data rate (DDR) interface for both address and data.

How to Optimize Energy Use in IoT Edge Devices

Battery life is a really key parameter for remote IoT devices. Replacing a battery can be time consuming and costly, or they may not be replaced and the device may fail as a result. A prime objective is to extend the time between recharges, or in the case of standard cells, the lifetime of the battery. There are many traditional approaches, but these lack the necessary system level perspective needed to fully optimize a design. Find out more . . . .
