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 dummy 做延时，但是在延时的同时会 ...

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 ...

按住boot不松，按下rst松开复位。 实际上上述操作可以不需要，直接输入以下命令会重启进入下载模式。 下载时注意如果已经有其他串口助手连接该串口需要先断开。

SPI（Serial Peripheral Interface） 协议是由摩托罗拉公司提出的通讯协议，即串行外围设备接口，是一种高速全双工的通信总线。它被广泛地使用在 ADC、LCD 等设备与 MCU 间，要求通讯速率较高的场合。 芯片的管脚上只占用四根线。 MISO： 主器件数据输入，从器件数据 ...

Abstract: This paper presents a method for applying a web server based on ESP32 to a small photovoltaic (PV) power system to monitor and/or collect the PV and the battery current, voltage data. The ...
