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?
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
Arduino MKR WiFi 1010 SPI Flash memory shield
I want to simplify the use of external SPI flash memory with my Arduino MKR WiFi 1010, therefore, I have created, a simple Shield PCB to achieve my purpose faster.
