I met some problems with my WiFi Kit 32 v1 board. (I checked against the official diagram and I’m sure it’s v1.)
After uploading the “WIFI_Kit_32_FactoryTest” example from the “Heltec ESP32 Dev-Boards” version 1.1.0, I can see messages in serial monitor saying “you can see OLED printed OLED initial done!” but the OLED does not work.
I also tried the ESP32\I2C_Scanner example which reported no I2C devices.
Later, I tried the GraphicsTest from U8g2 library with configuration (clock=15, data=4, reset=16), the OLED display worked well.
I have no clue how to further debug this. I would appreciate if you can help provide some suggestions.

我有一块 WiFi Kit 32 v1的板子（参照官方文档确认过版本了）。
刷了官方的 FactoryTest之后 OLED是不亮的，Serial可以读到信息。
后来我试了U8g2的图形库 GraphicsTest，设置了 (clock=15, data=4, reset=16)，刷完之后屏幕亮了，工作了。
