I recently bought a 2.9 inch e-paper display from waveshare and connnected it accordingly. I used provided code and uploaded it to the arduino. This, however resulted in the arduino spitting out "e-paper busy" into the serial monitor. I have triple checked all connections, tried with a nano board rewired everything and used differnet code example but nothing seems to resolve the issue. If anyone has knowledge in the subject and knows what might be the issue, please let me know.
Thank You!
