Adafruit Uncanny Eyes project for Teensy, help

[bmklawt]

Hello,

First time poster, new to this and have never tried anything like this before.
I built the uncanny eyes using these instructions https://learn.adafruit.com/eye-of-newt/introduction but the screen doesn't come on and I don't know if its a hardware or software issue, this is my first time ever using Arduino IDE or any type of programming for that matter.
I have been over the hard and believe it is all correct but can't be positive I did the soft ware right, i am using Arduino 1.8.13, Teensy loader 1.55, when I looked in the Arduino library these were already installed, Adafruit_GFX, Adafruit_BusIO, Adafruit_SSD1351. I'm not sure what other info you might need to be able to help me out.

Your help is greatly appreciated

I don't think Teensyduino 1.55 will work with Arduino 1.8.13 (which is rather old anyway).
Do a clean install of the latest version of Arduino 1.8.16 and then install Teensyduino 1.55 over that.

Thanks Pete,

I installed Arduino 1.8.16 and it worked out perfectly.
