Rapsberry Pico W and "Pico OLED 1.3" issues

ESPHome
1

Hi there,

my first steps into the ESPHome world drive me nuts. For my projects I want a Raspberry Pico W and a Pico OLED 1.3 display get going. The OLED display is a SH1107 controller with 64x128 pixels (see https://www.waveshare.com/wiki/Pico-OLED-1.3?Amazon). To be sure, the Pico is working right, I tested home assistant integration with the onboard LED of the Pico first. This works as expected. But the display doesn’t. Nothing shows up. The Pico doesn’t even show up in the network anymore (ping). “esphome run picodemo.yaml” compiles and flashes, but can’t connect afterwards.

Here’s my code:
