I have a LOLIN32 and want to connect it to a 7,5" Waveshare E-Paper. I select the GxEPD_SPI_TextExample and select the display class and then upload it. I do not get any errors, but the display simply does not react. i mapped the pins as documented in that sketch and i successfully ran test sketches to see if the board is working, but for some reason i just cant figure out how to reach the display.
this is the board i am using: https://www.amazon.com/ILS-LOLIN32-V1-0-0-Bluetooth-MicroPython/dp/B079121KR4/ref=sr_1_1?ie=UTF8&qid=1526622288&sr=8-1&keywords=lolin32+lite&dpID=51CqB6r9pIL&preST=_SX342_QL70_&dpSrc=srch
