我试了手头的两块Esp32 Wroom,都没有问题呀
>>> import network
>>> sta = network.WLAN(network.STA_IF)
>>> sta.active(True)
I (68968) phy: phy_version: 4102, 2fa7a43, Jul 15 2019, 13:06:06, 0, 0
True
>>> sta.scan()
[(b'28#301_ASUS', b'p\x8b\xcd\xc8\xba ', 1, -20, 3, False), (b'28#301_ASUS', b'\x0c\x12bb\xb7{', 1, -47, 3, False), (b'28#301_MI', b'\xecA\x18]
>>>
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

通过AMPY工具,我已经将MAIN目录下所有文件、文件夹都上传到ESP32中,但是还是没有WIFI信号。
另外我参考config.json文件,只看出以下的接线,有部分引脚接线不知道怎么接,比如TFT_ACC和MAX31855模块的HWSPI、CS、MISO、SCK,我按照你说的模块购买上面并没有这些引脚。
TFT | ESP32 |
---|---|
T_IRQ | 35 |
T_DO | |
T_DIN | |
T_CS | 25 |
T_CLK | |
MISO | 5 |
LED | 15 |
MOSI | 18 |
DC | 12 |
RST | 4 |
CS | 13 |
GND | GND |
VCC | 3V3 |
BUZZ | ESP32 |
---|---|
GND | GND |
I/O | 22 |
VCC | 3V3 |
MAX31855 | ESP32 |
---|---|
GND | GND |
VCC | 3V3 |
DO | |
CS | |
CLK |

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。
