[SOLVED] Cannot get display working on pico explorer base

Support
1

Hi, newbie to pico here so apologies as I expect I’m missing something obvious.

I have a pico and explorer base, have soldered it up, added the uf2 image, installed thonny, and am trying out the examples in pimoroni’s github.

So far it seems that just the display is not working:

  • I have a green light at the edge of the display section when I plug in power.
  • When I run something like rainbow.py nothing happens on the display, but putting some prints in the code I can see the loop is running
  • When I run button.py again nothing on the display, but by using prints I can see that each button press is being detected just fine
  • If I call display.get_bounds() then I get 240,240 returned which I would assume is correct
  • [Edit]: the speaker and thermometer both work too, it’s just the display as far as I can tell

Any thoughts on what I’m missing in order get things displaying? Thanks in advance!

Just updating that I’ve found the issue: studying the pin layout I noticed some poor soldering on the LCD pins. It’s now all working correctly :-)
