Hi,

I'm new to this and trying to get my first message displayed on the 2.9in flexible display using example code provided on the Waveshare website for the board used:

The upload appears to work well but nothing showing on the display. output from the serial monitor is:

Overriding BUSY wait: _PowerOff

E-Paper Test Complete.

Overriding BUSY wait: _Update_Full

Overriding BUSY wait: _Update_Part

Overriding BUSY wait: _Update_Full

Overriding BUSY wait: _PowerOff

Displaying test message...

Overriding BUSY wait: _PowerOn

Overriding BUSY wait: _Update_Full

Overriding BUSY wait: _PowerOff

E-Paper Test Complete.

Overriding BUSY wait: _Update_Full

Overriding BUSY wait: _Update_Part

I've tried the resistor positions in A and B, but no change. I'll try a new display to see if it's a hardware issue, but can you think of anything obvious that I may be doing wrong?

Thanks
Dave
