  Day 1, parts are here, and I'm playing with this cool OLED display from Adafruit. My goal today is get a logo on there, and maybe some sample text that will eventually show ping statistics. After this is complete I'll follow the outline in the project roadmap and move SPI pins around.

  13 is going to RST for OLED, but is used as SCK for EtherCard sketch, will assign something else for RST

  ~10 is CLK on OLED, that will be changed to 13

  12 is SS on OLED, this will be MISO, will pick something else for SS

  ~11 is "D/C" (data/command) on OLED, I don't know that is (SI?)

  8 will be used as SS for EtherCard

  Notes:
  

  Connections for ethercard on Uno

  SCK - 13 (19/PB5/PCINT5/SCK)
  SO - 12 (18/PB4/PCINT4/PWM/MISO)
  SI - ~11 (17/PB3/OC2A/PCINT3/PWM/MOSI)
  CS - 8 (14/PB0/CLK0/PCINT0/ICP1)

  GND goes to ground
  Vin goes to 5V
  DATA to digital 9
  CLK to digital 10 (SCK)
  D/C to digital 11
  RST to digital 13
  CS to digital 12
