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,...

I will add my opinion. Rejecting a RMI support in new ESP32 series like S3 is a very bad decision. Now I cannot to achieve high network performance. When I used LAN8720 with old chip, I could achieve up to 60Mbit/s in useful throughput. But now if I forced to use some SPI bridge...
The ESP32 has a hardware Ethernet MAC (EMAC). To add Ethernet to an ESP32 board you need to add a simple Ethernet PHY chip like the LAN8720. The PHY chip is connected to the ESP32 via a dedicated RMII interface. You can find lots of development boards with the LAN8720 (mainly becau...
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

power:设置ESP32某管脚,该管脚可以用来管理LAN8720供电,使能时输出高电平,失能时为低电平,写-1则不使用; mdc:mdc管脚编号,写-1则不使用; mdio:mdio管脚编号,写-1则不使用; type:PHY类型,ETH_PHY_LAN8720或ETH_PHY_TLK110; clock_mode:时钟模式,可选值ETH_CLOCK_GPIO0_IN、ETH_CLOCK_GPIO0_OUT、ETH_CLO...
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...
