This is my first try doing something like this. Which means my issue is pretty easy to solve I just have no Idea how to work with an Arduino.

This is what I'm using right now:

Waveshare esp32 Waveshare 7.5 e-paper display

I changed all my owm_credentials and used this in the code

static const uint8_t EPD_BUSY = 25; static const uint8_t EPD_CS = 15; static const uint8_t EPD_RST = 26; static const uint8_t EPD_DC = 27; static const uint8_t EPD_SCK = 13; static const uint8_t EPD_MISO = 12; // Master-In Slave-Out not used, as no data from display static const uint8_t EPD_MOSI = 14;

but I'm not getting an output on my display. But I'm getting some output on the Serial Monitor, idk if it's supposed to look like this. Prolly not.

You've got your serial port set to 9600baud, it should be 115200.

If you have a new style display from Waveshare, then you need to apply 3.3v to the PWR pin.

Are you getting weather data on the serial port?

[Trycilly]

Yes I have 3.3v appield to the PWR pin.

Also yes I 'm getting weather data on the serial port after changing it to 115200

Have you selected the correct display driver? It could be: GxEPD2_BW<GxEPD2_750, GxEPD2_750::HEIGHT> display(GxEPD2_750(/CS=/ EPD_CS, /DC=/ EPD_DC, /RST=/ EPD_RST, /BUSY=/ EPD_BUSY)); // B/W display Or: //#define GxEPD2_DRIVER_CLASS GxEPD2_750 // GDEW075T8 640x384, UC8159c (IL0371), (WF0583CZ09) //#define GxEPD2_DRIVER_CLASS GxEPD2_750_T7 // GDEW075T7 800x480, EK79655 (GD7965), (WFT0583CZ61) //#define GxEPD2_DRIVER_CLASS GxEPD2_750_GDEY075T7 // GDEY075T7 800x480, UC8179 (GD7965), (FPC-C001 20.08.20)

I used this one

GxEPD2_BW<GxEPD2_750_T7, GxEPD2_750_T7::HEIGHT> display(GxEPD2_750_T7(/CS=/ EPD_CS, /DC=/ EPD_DC, /RST=/ EPD_RST, /BUSY=/ EPD_BUSY));

This is a GxEPD2 library issue but you have to go through the display object lines to see which one works. It could be a driver does not yet exist for the display.

[Trycilly]

How can I check if I there is a driver for the display? And if I have it. I've seen it work with other people so could be I just did not download the driver? Waveshare 7.5 Inch E-Paper Raw Display Panel V2 800x480 This is the one I got. So I have to use the 7_5_T7 version. RIght?

[G6EJD]

Correct, but you didn’t select that one.

[Trycilly]

I did select that one

[G6EJD]

Try his example code, first one in the list, your display may be faulty. it’s an issue with GxEPD2 not this code.
