Im trying to use 4d systems' μOLED-128-G1 (SGC) display with the Serial_LCD library: http://embeddedcomputing.weebly.com/serial-lcd.html
. But i cant seem to get it to work when trying some of examples from that library. And I am using the Arduino UNO.
I connected the:
- OLED screen TX to Arduino RX pin 2
- OLED screen RX to Arduino TX pin 3
- OLED reset through a button
as shown in the Serial_LCD tutorial. Do I need a resistor for the connection between the OLED screen RX and Arduino TX?
There was one time when i was trying out the colour_main example, when i noticed a line with blue dots on top of the OLED display. I only noticed this later after i had uploaded the code. That did not display immediately. For this, i connected a a resistor for the connection between the OLED screen RX and Arduino TX.
However, I was able to use the following library: https://github.com/planetarian/4Duino
I dont know if I have made some silly mistake, but any help would be much appreciated!
edit: I was not able to display that line of blue dots again tho
