Modern applications are complex inter-connected collections of services and moving parts that all have the potential to fail or not work as expected. Flutter and the language it’s built upon, Dart, are designed for event-driven, concurrent, and, most crucially, performant apps. It’s important for any developer using them to have a decent selection of debug tools.

The C printf function is a staple of embedded development. It’s a simple way to get logs or debug statements off the system and into a terminal on the host. This article explores the various ways to get printf on Cortex-M microcontrollers.

Using an RTOS is often a tradeoff between the ease of decomposing tasks, with the complexity of the scheduler itself. There exists a middle ground between highly complex systems that may require an RTOS, and simpler ones that can be easily modeled using a super loop.Since ARM is the most popular embedded CPU and almost every ARM processor has a hardware scheduler, it would be interesting to make a compact framework utilizing these features.

In the dynamic realm of embedded systems, the right combination of hardware and software components can transform the development process and empower engineers to build robust and efficient solutions. This article explores a streamlined device-to-cloud embedded design utilizing the STM32G0 Nucleo board from STMicroelectronics, an AWS IoT ExpressLink module from Espressif, AWS IoT Core for secure MQTT communication, and Memfault for remote debugging.

Connected devices require a secure point-to-point channel to ensure that there is no possibility of exposing important data for the integrity of an embedded system. This is especially true when we talk about over-the-air (OTA) software updates, where the new firmware has a long way to go before reaching its destination and being installed by our bootloader. In this publication, we will explore a simple method to encrypt the firmware using the AES algorithm, using open-source libraries in Python.
