Wireing correct but no Display output

Closed this issue 4 years ago · 2 comments

Uploading the code and the Wifi Setup works perfectly.
I even can reach the WEB GUI of myClock with a web browser.
But the display shows nothing.

Before I tried the first version of the Morphing Clock (https://www.instructables.com/id/Morphing-Digital-Clock/). This works with no problems. The display shows the time.
I also tried the PXMatrix examples. All the examples worked.
So the wireing seems to be correct.

Any ideas?

Found the problem.
Had to uncomment "#define double_buffer"

Odd! I tried recompiling with latest library and now mine no-longer requires that double_buffer, and does not work, with it. Previously it was required. Not sure what changed, but thanks for the find! :)
