Raspberry Pi Pico and rp2040 boards: how to use SD card – 5
We have already talked about the internal flash memories for rp2040 boards and other microcontrollers, which are very useful for storing pages or static files. However, they are not suitable for logging or similar applications, so we will learn how to connect and use an SD card which can have a lot of space, a very small form factor, and low power consumption.
esp32 and esp8266: FAT filesystem on external SPI flash memory
In this article, we are going to integrate into our ESP32 or esp8266 an external flash memory in addition to the internal one.
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.
Here we are… again. 4°
Merry Christmas and happy new year 2022 from www.mischianti.org
Raspberry Pi Pico, and other rp2040 boards:Â 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.
i2c Arduino SAMD MKR: additional interface SERCOM, network and address scanner
I love the I2C protocol, and when I need a sensor, every time I try to find one with this protocol, I have also written some libraries for various sensors that use I2C.
In this article, we will learn I2C basics, analyze the Arduino SAMD MKR management, add interfaces with SERCOM, and create a heterogeneous network.
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.
STM32: add SPI flash memory with FAT FS
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.
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
