Using Waveshare Epaper with HeltecV2 (Lora)

[tuhorkko]

I would like to use my epaper with HeltecV2 and LoRa. Is there something wrong with my pinmapping. I use LMIC which works fine but Epaper does not! For E-paper is use GxEPD-library (works fine with Arduino UNO), But I am totally lost with pinmapping. Is there something wrong with my pinmapping:

//For LMIC:
const lmic_pinmap lmic_pins = {
.nss = 18,
.rxtx = LMIC_UNUSED_PIN,
.rst = 14,
.dio = {26, 34, 35},
};

//For E-paper:
GxIO_Class io(SPI, /CS=5/ 17, /DC=/ 23, /RST=/ 16); // arbitrary selection of 17, 16
GxEPD_Class display(io, /RST=/ 16, /BUSY=/ 2); // arbitrary selection of (16), 4
//E-paper CLK (YELLOW) connected to Heltec pin5
//E-paper DIN (BLUE) connected to Heltec pin27
//
