OLD Brick The OLD brick contains a 0.96 inch SSD1306 OLED display. The OLD brick has two I2C ports (left and right) for communication with the other I2Bricks Serial Port Commands: old0 - clear the OLED screen old1=text1 - write text1 to the first line old2=text2 - write text2 to the second line old3=text3 - write text3 to the third line old4=text4 - write text4 to the fourth line Python Functions: old(port, line, text) - write text to the line (0-4) of the OLED screen. If line=0, then clear the screen

#Example Python code to test OLD brick. OLD is connected to ARD.

from I2Brick import *

port = I2Brick('COM4')             #Windows: Initialize serial communication with I2Bricks
#port = I2Brick('/dev/ttyUSB0')    #Linux: Initialize serial communication with I2Bricks

print(ard(port))                   #test communication between ARD and PC


old(port,0,'')                     #clear screen
old(port,1,'test line 1')          # write to the first  line'test line 1'  
old(port,2,'  test line 2')        # write to the second line'  test line 2'
old(port,3,'    test line 3')      # write to the third  line'    test line 3'
old(port,4,'      test line 4')    # write to the fourth line'      test line 4'

port.close()
