ในคอมผม เปลี่ยน ssid pass token แล้วครับ

ขอดูโค้ตที่ใช้ด้วยครับ

ลองดู Library ตัวนี้ดูครับ (แค่แนะเป็นแนวทาง)
ESP8266 and ESP32 OLED driver for SSD1306 displays
I2C display driver for SSD1306 OLED displays connected to ESP8266, ESP32, Mbed-OS
#include "SSD1306.h"
SSD1306Wire display(0x3c, D1, D2);
voild setup{
display.init();
display.flipScreenVertically();
display.setFont(ArialMT_Plain_16);
display.setTextAlignment(TEXT_ALIGN_LEFT);
}
voild loop{
display.display();
display.clear();
display.setFont(ArialMT_Plain_10);
display.drawString(15, 0, " SSID >> ");
display.setFont(ArialMT_Plain_10);
display.drawString(0, 15, " BBBBB "));
display.setFont(ArialMT_Plain_10);
display.drawString(15, 30, " IP >> ");
display.setFont(ArialMT_Plain_16);
display.drawString(0, 45, "AAAAAA");
delay (1000);
}
