ARDUINO PORTENTA H7 Tutorial

Portena H7 simultaneously run high level code along with real time tasks. H7 main processor is the STMICROELECTRONICS dual core STM32H747 including an ARM CORTEX -M7 running at 480 MHz and ARM COTEXT M4 running at 240MHz. The two core communicate via a Remote Procedure call mechanism that allows calling functions on the other processor seamlessly. The Portenta H7 simultaneously runs high level code along with real time tasks, since it includes two processors that can run tasks in parallel. For example, it is possible to execute Arduino compiled code along with MicroPython one and have both cores to communicate with one another. The Portenta functionality is two-fold, it can either be running like any other embedded microcontroller board or as the main processor of an embedded computer. There are many features in one module STM32H747 dual-core processor 8 MB SDRAM 16 MB NOR FLASH 10/100 ETHERNET PHY USB HIGH SPEED SECURE ELEMENT WIFI/ BLUETOOTH MODULE UFL CO...

Getting Started with mmWave Sensor MR60BHA1 and Arduino

Introduction : The MR60BHA1 mmWave Sensor is a compact and efficient radar sensor that utilizes millimeter-wave technology to detect objects, measure distance, and track motion. With its high precision and low power consumption , this sensor is ideal for applications in robotics, automation, and security systems. . Millimeter-wave (mmWave) sensors operate at extremely high frequencies, typically in the 30GHz to 300GHz range, allowing them to detect objects with great accuracy regardless of lighting conditions. Unlike optical sensors, mmWave sensors can penetrate fog, dust, and even certain materials, making them reliable in harsh environments. The MR60BHA1 is one such sensor that operates at 60GHz , providing precise motion detection and range measurement capabilities. By integrating the MR60BHA1 with an Arduino , users can develop a variety of projects, such as human presence detection , security systems , and robotic navigation . In this blog, we will explore how to interface...
