I have a Seeeduino 4.2 board and Small e-Paper Shield V2 - and a Pervasive Displays 1.44" panel (E1144CS021). When I try to run the examples, it doesn’t work (nothing shows on the display). I have a formatted SD card plugged in also.
It appears that the library is making to the call for SPI.begin(). At that point, if the SD card is not inserted, the LED blinks slowly… and when the SD card is inserted, it blinks rapidly.
Any insight into what’s wrong?
