P positrom2 Active Member Licensed User Longtime User Dec 15, 2016 #1 I got an 1306 128x64 OLED (Waveshare). A line like Code: ssd.GFX.DrawLine(0,0,127,31,ssd.WHITE) diagonally covers the whole screen, so it appears that the y-axis in B4R is only 32 pixel wide. The Adafruit library supports 128x64 and 128x32 displays. https://github.com/adafruit/Adafruit_SSD1306 Is there a choice in B4R for those display types?

P positrom2 Active Member Licensed User Longtime User Dec 16, 2016 #3 Thank you, that worked. Yesterday night I had tried that with the Arduino IDE, but it did not work. The Nodemcu apparently got more and more petulant and I stopped working. This morning I had changed the USB cable to a "thicker" one. I hope the reliability becomes (and stays) better. Though finally not a big project, I will post it when finished (graphing BMP280 data on OLED). Upvote 0
