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 ...

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.

Today, the demand for reliable and efficient communication systems is more critical than ever, especially with the rapid growth of IoT applications. In this paper, we propose the implementation of a ...

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 ...
