Electronic, 3D printing and embedded programming
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.
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.
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.
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
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.
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.
In this article, we are going to explore the w5500 module with our Raspberry Pi Pico, w and the other rp2040 boards. w5500 is a quite powerful device that allows an Ethernet wired connection.
It’s fundamental for data logging the interfacing with SD cards. STM32 doesn’t support well native SD library, so we will use the SdFat library, which has an Adafruit fork also that we’ll use for other purposes.
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.
