OLED initialization

After using the OLED initialize Block, and then looking at code, there is always an extra number in the code, so far a "2".

For example: oledc_init(9, 8, 7, 6, ,5, 2);

a. What is the purpose of the "2" ?

    I downloaded the updated Library and checked OLED.H which says the following: 
    /**
 * @brief Initializes the OLED screen by setting up it's SPI and control pins.
 *
 * @param SID which pin is connected to the Serial Data In pin, marked "DIN".
 * 
 * @param SCLK which pin is connected to the Serial Clock pin, marked "CLK".
 *
 * @param CS which pin is connected to the Chip Select pin, marked "CS".
 *
 * @param RS which pin is connected to the Read Status pin, marked "D/C".
 *
 * @param RST which pin is connected to the Reset pin, marked "RST".
 *
 * @param screen_rotation Sets up the OLED screen and establishes its orientation. (0) means the pins are pointed upwards, 
 * (1) means the pins are pointed to the left, (2) means the pins are pointed down and
 * (3) means the pins are pointed to the right.
 */
void oledc_init(char SID, char SCLK, char CS, char RS, char RST, char screen_rotation);

    You're welcome. How are things going in Blockly, in general?
