This project demonstrates full-duplex SPI communication between an ESP32-S3 (running Zephyr RTOS) and an Arduino Uno. The goal is to send one full string from the master (ESP32-S3) and receive one ...

In case you missed it, the big news is that a minimal Arduino core is up and working on the ESP32. There’s still lots left to do, but the core functionality — GPIO, UART, SPI, I2C, and … ...

Mediante comunicación serial entre ESP32 y un Arduino Uno maestro se logró controlar varios Arduinos Uno esclavos. La idea de este proyecto es que cada arduino uno esclavo sea el encargado de ...

Using SPI Protocol in Arduino. Before start programming for SPI communication between two Arduinos.We need to learn about the Arduino SPI library used in Arduino IDE.. The library <SPI.h> is included ...

In this tutorial, we will learn how we can use the LoRa module SX1278 with ESP32. Here we will use two LoRa modules- one with ESP32 and another with Arduino Board. ESP32 LoRa setup will request the ...

The UNO R4 WiFi is a denser board as it uses the empty board space of the Minima for an 8 by 12 LED matrix and an ESP32-S3-MINI-1 module. ... The RA4M1 integrates two SPI ports, two I²C ports plus ...
