text: Using i2C SSD1306
  I am learning how to use the new board. Debugging is a lot easier using an LCD so I am trying to use the attached code with an SSD1306 but I am getting the error below. I would appreciate finding out how to fix this or if there is a simple program showing how to use an I2C LCD that would be also great.
  Thanks in advance.

  @brossingo FWIW, I managed to get such a display running with the development release firmware (version 1.20rc4) in combination with the
  write_data()change that robert-hh mentioned. This newer release is required in order to be able to make use the
  framebufclass.
  Here's a post with my notes:
  @brossingo Change the method write_data() in class class SSD1306_I2C(SSD1306) to:
  def hw_write_data(self, buf): self.i2c.writeto(self.addr, b'\x40'+buf)
  The code in that lib is for the micropython.org branch and was never ported.
  @jimmie hey, did you manage to make it work? Because when I launch a quite similar piece of code to display things on screen, I got the following mistake :
  Traceback (most recent call last):
  File "<stdin>", line 133, in <module>
  File "<stdin>", line 112, in init
  File "<stdin>", line 40, in init
  File "<stdin>", line 67, in init_display
  File "<stdin>", line 92, in show
  File "<stdin>", line 122, in write_data
  AttributeError: 'I2C' object has no attribute 'start'
  I use the ssd1306.py as described on this link :.
  Thank you @robert-hh .
  changed to the code below and it now works.
  i2c = I2C(0, I2C.MASTER, baudrate=100000, pins=("P9","P10")) oled = ssd1306.SSD1306_I2C(128, 32, i2c)
  @jimmie looks like line 9 should start with:
  i2c = I2C(0, ........
  And then in the next line i2c instead of I2C has to be used.
