Sometimes Display work and most time Display not work #102

Closed Bunoklm closed 4 months ago

Bunoklm commented 4 months ago

Every wire is connected and working. I am using another ESP, the Wemos D1 Mini, and powering it over the integrated USB port. However, most of the time, the screen does nothing. The ESP starts and in 1 out of 100 cases, the display works. In the other 99 cases, the ESP32 starts, connects to Wi-Fi, asks the API for the latest data, but the screen does not refresh.

Sometimes it says that the battery is empty.

You may need to check your wiring. Note that some pins may have multiple uses. I cannot offer much support with the Wemos D1 Mini since I do not have one and have not tested this software on it. Have you edited the platform.ini file to use the right microcontroller controller config for the Wemos D1 Mini.

This indicates improper wiring or software configuration for both the BME and display.

Yes, I don't have the sensor, but it has worked without it before. Or do I need it to update the display?

Yes, I have edited the platform.ini. This problem has been present since I provided the software with the API key. However, when I delete the key, the display still does not work.

Do you have a small program with which I can test the display?

lmarzen commented 4 months ago

It will work without the sensor

lmarzen commented 4 months ago

If you want to try examples focused on just testing the display, you can go to the display driver library repo found here: https://github.com/ZinggJM/GxEPD2

When I delete the Wi-Fi, the display does something but just shows grey.
