Bonsoir,
You need to connect 5 pins:
Screen +5V to Arduino +5V
Screen Ground to Arduino Ground
Screen TX to Arduino SoftwareSerial RX = pin 2
Screen RX to Arduino SoftwareSerial TX = pin 3
Screen RESET to Arduino pin 4
The screen RESET is required by the uOLED display as its built-in Goldelox graphic controller doesn't feature auto-baud, contrary to the Picaso on uLCD screens.
On the setup() function, if myScreen is the name of your screen, include
myScreen.begin(4);
Check the example serial_software_main.pde.
