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 ...

We previously noted the ESP32 Arduino Core 3.0.0 Alpha release added support for ESP32-C6 and ESP32-H2 among other changes. The good news is that Arduino ESP32 Core 3.0.0 is now considered stable, and ...

Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

Unlike other ESP Development Boards, the ESP32-CAM has no USB connector to connect it to a computer. This might be confusing for beginners when they try to program this development board for the first ...
