Wiring up the picture maker

A project log for Thing2Ping

Because sometimes link lights lie.

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


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)

OLED display on SPI

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
