The `demo.py` example should definitely show things up on the screen.

How does the soldering look on your Pico? Try running this:

```auto
import picoexplorer as explorer

width = explorer.get_width()
height = explorer.get_height()

display_buffer = bytearray(width * height * 2)  
explorer.init(display_buffer)
explorer.set_pen(0,0,0)    
explorer.clear()
explorer.set_pen(255,255,255)
explorer.text("Hello world!", 20, 20, 100, 4)
explorer.update()

```
