一、配置CubeMax工程 二、配置系统时钟 因为LAN8720使用的是外部25MHz的晶振,所以不需要单片机输出时钟 三、配置ETH和LWIP参数 四、更改代码 LAN8720A在初始化的时候需要复位,因此在ethernetif.c的 static void low_level_init(struct netif *netif) 函数中添加LAN8720A 的复位程序 再mian函数主循环中添加一下代码,...

1) Old ESP32 series + cheap LAN8720 with high speed network performance 2) New ESP32 series + cheap W5500 but with slow and braked network performance (thanks to SPI) 3) New ESP32 series + expensive W5300 with great count of used pins Rejecting a RMI support is very very bad decision...
Arduino Library for ESP32/S2/S3/C3 asynchronous MQTT client implementation. This library, ported to support ESP32/S2/S3/C3, WT32_ETH01 (ESP32 + LAN8720), ESP32 using LwIP ENC28J60, W5500, W6100 or LAN8720. Supporting TLS/SSL for MQTTS Client - khoih-prog
The PHY chip is connected to the ESP32 via a dedicated RMII interface. You can find lots of development boards with the LAN8720 (mainly because it is a very cheap chip). For reasons unknown they removed the EMAC from the ESP32-S3. ...

(可以把模块上的晶振拆了,然后用飞线连接ESP32 GPIO17和LAN8720模块晶振时钟输出脚,可以大大提升通讯稳定性) 另外如果使用外部时钟连接到GPIO0时还需要特别注意电路设计: Because GPIO0 is a strapping pin for entering UART flashing mode on reset, care must be taken when also using this pin as EMAC_TX...
LAN8720A 可以通过 PHYAD0 引脚来配置,该引脚与 RXER 引脚复用,芯片内部自带下拉电阻,当硬复位结束后, LAN8720A 会读取该引脚电平,作为器件的 SMI 地址,接下拉电阻时(浮空也可以,因为芯片内部自带了下拉电阻),设置 SMI 地址为 0,当外接上拉电阻后,可以设置为 1。
We have so far used ESP32 (with LAN8720), but now upgraded to ESP32-S3 using W5500 for a wired Ethernet connection. W5500 is officially supported by ESP-IDF and the connection works perfectly for all tasks except mDNS multicast packets. Using Wireshark we can clearly see that the packets...
