Does any of you know what happens to my e-Paper (raw display -- see photo)
Photo link: (not sure what I can't attach the photo)
I design my own MCU board for my project. I just add the driver circuit as described in the datasheet (Waveshare 1.54in B/W/Y), but use a different inductor and Mosfet due to the availability. I use the sample code provided by Waveshare, and I got this problem. I cannot do anything else with the e-Paper display.
I really appreciate it if someone can help me to figure out the problem.
