I am using ESP8266 nodemcu V3 with built-in oled display. when i try to use the oled with Wire.begin(4, 5); it works great. but when i try to use these scl and sda pins in A_config.h, it doesnt show anything in the display. i tried some other default scl, sda pins too. nothing worked

研究方向
Examine the A config.h file in the repository to see how the SCL and SDA pins are defined for the OLED display. Compare the initialization code that uses these config pins with the direct Wire.begin call that works. Look through the issue comments for any additional troubleshooting steps or maintainer suggestions. The goal is to identify why the config based approach fails to produce display output.
