还在为MCU的WiFi连接方案发愁？RT-Thread社区开源ESP-Hosted驱动，通过标准SPI接口即可实现，并且该仓库已整理成RT-Thread软件包。RT-Thread ESP-Hosted项目在 MIT license下作为一个整体，但包含第三方代码在其他许可下。请仔细阅读以下不同许可代码的说明。 目录 用途 概述 使用 硬件连接 构建ESP32固件 检查 ...

ESP32 官方提供的 spi 驱动能够满足大多数的 spi 外设。但遇到 ch9434，一款四通道串口芯片时发现却无法满足。 ch9434 的 spi 时序要求 无法满足的时序是：写入时地址和数据之间需要1微妙延时，读取时需要3微妙延时。 ESP32 提供了 ...

Waveshare ESP32-P4-Module-DEV-KIT credit card-sized board may look like a Linux-powered Raspberry Pi SBC, but instead, it’s based on an “ESP32-P4-Module” comprised of a 400 MHz Espressif ESP32-P4 RISC ...

ESP32可以使用两种方式接入，一种还是传统的AT模式，协议栈运行在ESP32上，接口可以选择UART，SDIO和SPI; 还有一种是ESP32作为网卡的模式,透传以太网包，协议栈跑在主机上,接口也可以使用UART，SDIO， SPI。 两者官方都在githun上有开源项目。

注意： SPI主驱动程序的概念是将多个设备连接到一条总线（共享一个ESP32 SPI外设）。只要仅通过一个任务访问每个设备，驱动程序就是线程安全的。但是，如果多个任务尝试访问同一SPI设备，则驱动程序不是线程安全的。在这种情况下，建议执行以下任一操作： * 重构您的应用程序，以便每个SPI ...

The ESP32 collects data from sensors. All of the data are saved in a text file on an SD-card, which is connected with ESP32 SPI pins. The text file is saved on the SD card for a week or longer, after ...
