I´m using Spark Fun Micro Pro board 5V: https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide/hardware-overview-pro-micro
and to that i´ve hooked a true color OLED from digole: http://www.digole.com/index.php?productID=859
Got a wire from OLED "data" to Pro micro "TX"-pin.
The OLED starts up and runs the start up screen, but the sample code I uploaded won't run. And that code looks like this:(the code is pretty long, if anybody would have a simplified sample code it would be much appreciated!! To get the OLED to show a simple "Hello World" would make me a very happy man! =)
Thanks!
