BNO055: power modes, accelerometer and motion interrupt – 4
In this article, we are going to explore the power modes of BON055 and focus on accelerometer features and management.
Raspberry Pi Pico, and other rp2040 boards: WiFiNINA with ESP32 WiFi Co-Processor
Even though Raspberry Pi Foundation has released the Pico W version, I still find this tutorial useful for adding WiFi to rp2040 boards using an ESP32.
We will use an esp32-wroom-32 (or esp32-s) as WiFi coprocessor and the full potential WiFiNINA library to handle it.
What do you want? A microcontrollers performance comparison
Whoever has started to peek into the wonderful world of small electronics will undoubtedly have read about Raspberry Pi or Arduino boards. This is where I personally started to ask myself, what is the right board for which project?
BNO055 for esp32, esp8266, and Arduino: features, configuration, and axes remap – 3
In this article, we are going to explore all features of BON055 and how to configure It.
ESP32: ethernet enc28j60 with plain (HTTP) and SSL (HTTPS)
enc28j60 is one of the cheapest device for wired connections; in this article, we’ll learn how to manage this device for plain and SSL connection with our ESP32
BNO055 for esp32, esp8266, and Arduino: wiring and advanced Bosch library – 2
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.
ESP32: ethernet w5500 with plain (HTTP) and SSL (HTTPS)
Many people ask me for some examples of wired connections; in my mind, the first thing I thought of is the w5500 device, one of the most famous and powerful. We’ll start to learn how to manage plain and SSL requests.
BNO055 accelerometer, gyroscope, magnetometer with basic Adafruit library – 1
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.
STM32F4 Black-pill: WiFi shield (WiFiNINA)
For me, It’s very important the network connection and network limitation on STM32F4 It’s very tedious. Adafruit offers a solution, but I think that a shield It’s more usable.
