The ESP32 boasts a crucial capability that streamlines the sharing of firmware, which most manufacturers widely utilize. This capability involves creating a pre-compiled binary file containing the sketch portion (or filesystem). In this article, we will create a binary file for the filesystem and proceed to flash the ESP32 using the Espressif Download Tool.
An essential feature of ESP32 core that simplifies the sharing of firmware (and most manufacturers use it) is to generate a pre-compiled binary file with only the sketch part (or filesystem).
In this article we will generate a firmware binary from the command line.
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.
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.
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
