I played for a while with the photon and now trying to get it working with the Waveshare 4.3inch e-Paper (http://www.waveshare.com/wiki/4.3inch_e-Paper). I am struggeling with the serial communication between the photon and the display. It is working fine with my arduino. Since you have to use the serial1 ports for external communication on the Photon I had to adapt the library. But it is hard to monitor or even to debug if this is working as it should…
Has anyone experience with this kind of display? Or do you have a suggestion how to debug the serial communication on serial1 at the photon?
Thanks in advance!
