FT2232H D2XX for OSX and SSD1306 controller via I2C MPSSE FT232H

Description:

Connect OLED with SSD1306 Controller to my MacBook Pro with MPSSE cable using FTDI D2xx driver

Background:

I couldn't find an example using the D2XX driver on OSX to connect to a Graphic OLED with the SSD1306 controller via I2C. I roughly combined the adafruit graphics library with the code in the USB to I2C example from FTDI to fill the gap.

Defaults to the FT0EARPI Cable

Runs on Mac OSX Sierra

Based on Adafruit graphics library https://github.com/adafruit/Adafruit-GFX-Library

Link to USB 3.3v cable https://www.amazon.com/gp/product/B00HKK4SCO/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

Command line options

./oled -l cycle once through the images in the images folder

./oled 5 -i image.bmp The argument supplied is timeout 5 image image.bmp

./oled defaults are 3 second delay filename image.bmp

./oled -t 100 100ms timeout between frames

./oled -d 1000 1s delay before turning off last image

./oled -D FTYPX46A -l Use the FTYPX46A 5V Cable

./oled -D Use the FT0EARPI 3.3v Cable — This is the default cable

Try not to keep the same image on the screen for too long, you will burn up the OLED.
