搜索不到WIFI信号 #8
Comments
我试了手头的两块Esp32 Wroom,都没有问题呀
自己作为AP,或者作为station去连接别的AP也都正常 你贴的图上我也没看到报错信息 |
TFT的ACC是给屏幕供电的GPIO,接到屏幕的VCC上,但实际上你把屏幕的VCC直接接到3.3V即可,程序本身并没有关闭屏幕的操作。T_DO直接并联到TFT的MISO,T_DIN并联到TFT的MOSI,T_CLK并联到TFT的SCK。 MAX31855的DO就是MISO,CLK就是SCK。hwspi是硬件spi的编号,不是GPIO,mpy文档里有写。 你硬件线没接好的话,main.py执行的时候肯定在初始化硬件的时候就出错终止了,不会执行到最后打开AP信号的代码,所以没有wifi信号。 |

使用ESP32烧录座+ESP32-WROVER-B模块的方式烧录固件发现无法搜索到WIFI型号,ES32-WROOM-32模块也有尝试
