Describe the bug SSD1306 display(0x3c, oled_SDA, oled_SCL,GEOMETRY_128_64,I2C_TWO);//0x3c, SDA, SCL i did seclect the I2C_TWO,but it don't work

and there is a only seclection :HW_I2C,a soft I2C would be better,SF_I2C (in oleddisplay.h 146) just for esp device compatibility,this wouldn't be big problem.

(thank u for help,and the lib really give a lot of help)specilly esp32c3 can't use u8g2

esp32-c3 workout by this way,if u really need use two i2c Wire.begin(oled_SDA,oled_SCL); display.drawString(0,0,"Hello World from ESP32!"); display.display(); Wire.end();
delay(1000); Serial.println("running"); Wire.begin(ads1115_SDA,ads1115_SCL); ads_str = ads.computeVolts(ads.readADC_SingleEnded(0)); Serial.println( ads_str); Serial.println(double (ads.readADC_SingleEnded(0)*4.096/32768) ); Wire.end();
