There is one more thing, the ESP32 takes 7 bit address for the I2C device. All the functions, which are included in the library of ESP32 will shift this address to the left by 1 bit, 0x27<<1, and the LSB here will be responsible forread(1)/ write(0)operation. ...
lcd_rows:是LCD的行数,它是2。 charsize = LCD_5x8DOTS:是一个字符的大小。默认值为5×8点。 所以它可以这样写: LiquidCrystal_I2Clcd(0x27,16,2); 还有初始化 lcd.begin(12,14); 这里就表示ESP32 GPIO12连接到LCM1602 SDA,ESP32 GPIO14连接到LCM1602 SCL。
