White vertical bar on FeatherWing OLE on Argon

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 :frowning:

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

display.setTextColor(0x0000, 0xFFFF); // white fg, black bg

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 :slight_smile: 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!
