This function is used to refresh the OLED display. It loops through the rows (from 2 to 7) and sets the page address (0xb0 + i) and column address (0x00 and 0x10) for each row. Then it writes the data stored in the OLED_GRAM array to the display using OLED_WR_Byte function. OLED_GRAM is a 128x8 array that stores the data to be displayed on the OLED. Each element in the array represents a single pixel on the display.
