White vertical bar on FeatherWing OLE on Argon

[ndipatri]

Hello, i’ve wired up a FeatherWing OLED display on a Tripler with an Argon. I’m able to push PNGs but my text is showing up as individual white vertical bars. I’ve tried using Fonts and that didn’t help

I’m following all examples… Here’s an excerpt of my attempt:

display.setTextSize(3);
display.setTextColor(0x0000, 0xFFFF); // white fg, black bg
display.setCursor(0,0);
display.println("A");
display.display();

The above ‘A’ produces a single vertical bar.

I’m using the Adafruit_SSD1306_RK library.

Have you tried with text size 1 instead of 3?

Firstly, thank you for the reply I did try with size of 1 earlier… but just tried in again in case. No good. The bar is smaller. So it’s almost like a width thing…

I figured it out. I was no properly clearing the display first. The example .ino code at https://github.com/rickkas7/Adafruit_SSD1306_RK/blob/master/examples/OLED_featherwing/OLED_featherwing.ino was a great help.

Thanks anyway!
