This latest article in the series explores how to use the BNO055 sensor with ESP32, ESP8266, and Arduino to achieve gyroscope high rate and any motion interrupt. The BNO055 sensor combines an accelerometer, magnetometer, and gyroscope in one module, making it ideal for accurate orientation tracking.
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short-distance communication, primarily in embedded systems.
SPI devices communicate in full duplex mode using a master-slave architecture with a single master. The master device originates the frame for reading and writing. Multiple slave-devices are supported through selection with individual slave select (SS), sometimes called chip select (CS), lines.
Continue the series of article about the Bosch sensor BNO055. In this part of the tutorial, we will learn how to enable the INT pin of the BNO055 and configure the accelerometer High G Interrupt. The High G Interrupt is triggered when the accelerometer detects a sudden acceleration event that exceeds a specified threshold and duration. This can be useful for detecting impacts, falls, or other sudden movements in a variety of applications.
In this article, we are going to integrate into our ESP32 or esp8266 an external flash memory in addition to the internal one.
In this article, we are going to explore the power modes of BON055 and focus on accelerometer features and management.
In this article, we are going to explore all features of BON055 and how to configure It.
The first SMT32 prototype boards don’t have an embedded SPI Flash, but the latest, like the WeAct STM32F4 board, has a footprint to add It. And for me, It’s very useful. The only problem Is that this Core doesn’t have a native library, so we will use the Adafruit one.
This is the second article on bno055. If you need basic management, you can refer to the previous article “BNO055 accelerometer, gyroscope, magnetometer, and orientation software”, but if you need advanced management (and more complex) with interrupt, you must read this article also.
Arduino SAMD devices don’t have an internal SPI flash memory, but it is clear that a fast and small memory like that can be very useful, so we are to talk again (and again and again and again…) about storage systems.
We are going to discover BNO055, a triaxial accelerometer, a triaxial gyroscope, and a triaxial geomagnetic sensor with a 32-bit cortex M0+ microcontroller in a single package.
In this first chapter, we start a basic usage.
