A robust, interrupt-driven SPI driver for ESP32-S3 using ESP-IDF 📖 Project Overview This project implements a low-level, interrupt-driven SPI (Serial Peripheral Interface) driver for the ESP32-S3 ...

SPI messaging is currently arranged in 2 layers. The first is the spi protocol. The spi protocol is the lowest level. It defines a standard packet for all SPI communication. It is a 256 byte packet ...

Waveshare has recently released the ESP32-S3 2.06-inch AMOLED Touch, an ESP32-S3-based watch devkit with Wi-Fi 4, Bluetooth 5 ...

Scratch has some Arduino extensions to begin with. And mblock.cc which is clone of Scratch in addition to their robots support, has a ton of microcontroller extensions.

The esp32 actually has four SPI buses, 0 to 3. SPI0 is reserved for the flash chip the program code is stored on. It has a special connection to the CPU memory bus.

This study investigates the performance of the ESP-NOW communication protocol on ESP32 devices through field testing and Quality of Service (QoS) analysis. ESP-NOW is a lightweight, low-energy ...
