esp32-mini-1能用于以太网吗?发现gpio16 17没有 要注意什么?
最近用esp32-mini-1画了个板子,接上了lan8720a. 用gpio0做ref时钟 因为gpio16 17都没引出。 gpio0又接到ch340用于启动时选择下载程序还是启动。 但还没调通。不知道什么原因。 1,esp32-mini-1能用于以太网吗? 2,要注意些什么? 现在把调试时的打印信息贴上来: I (28) boot: ESP-IDF v4.4-dirty 2nd stage bootloader I (28) boot: compile time 13:24:39 I (28) boot: chip revision: 3 I (31) boot.esp32: SPI Speed : 40MHz I (36) boot.esp32: SPI Mode : DIO I (40) boot.esp32: SPI Flash Size : 4MB I (45) boot: Enabling RNG early entropy source...
