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 ...

SPI_AVR_loader SPI loader running on Arduino Uno using SPI to load code onto other AVR chips (like ATtiny85) This code runs on an Arduino Uno and can be used to use SPI to program another AVR device.

In the above scenario, the new library will generate a blocking SPI transaction, thus allowing the first main loop SPI transfer to complete, before attempting the second transfer.

The Arduino Uno R4 minima costs around ₹1400 while the Uno R4 WiFi costs around ₹2300. Now, the Chinese maker electronics manufacturer Maker Go comes with a solution for that, an Arduino Uno clone for ...

Expected to be available late Mai 2023 the Arduino UNO R4 is the long-awaited update of the UNO R3 based on a Renesas RA4M1 32-bit ARM Cortex-M4 MCU.

The Arduino UNO R4 boasts a 3x performance increase over the UNO R3 and , in addition, SRAM has been upgraded from 2kB to 32kB, and flash memory from 32kB to 256kB to support more complex projects.

The release of the next-generation UNO board by Arduino represents a considerable upgrade to its 8-bit technology.

Arduino UNO R4 Minima and WiFi boards powered by a Renesas RA4M1 32-bit Arm Cortex-M4F microcontroller and equipped with an optional ESP32-S3 WiFI & BLE module are now available for respectively $20 ...
