i put oled128*128 with ssd1327 and ds3231 on the same SCL and SDA but they can not work together. `#include "DS3231.h"

include

include

ifdef U8X8_HAVE_HW_SPI

include

endif

ifdef U8X8_HAVE_HW_I2C

include

endif

RTClib RTC;

include

U8G2_SSD1327_EA_W128128_F_SW_I2C u8g2(U8G2_R0, / clock=/ SCL, / data=/ SDA, / reset=/ U8X8_PIN_NONE);

LiquidCrystal_I2C lcd(0x27, 16, 2); void setup () { u8g2.setI2CAddress(0x3C*2); u8g2.begin(); delay(5000); Serial.begin(57600); Wire.begin(); //lcd.init();

// Print a message to the LCD. //lcd.backlight(); //lcd.print("Hello, world!"); // u8g2_SetI2CAddress(u8g2.GetU8g2(),0x3C*2);

}`

You must use the HW I2C constructor: U8G2_SSD1327_EA_W128128_F_HW_I2C
