Busy Timeouts using Wavwshare Board

Other Hardware Displays

Hi, is there clarity on the number of reasons for Busy Timeouts using Wavwshare Board and 7.5inch epaper?

No, impossible if you do not specify in detail your issue. Post links to your devices!
And the library you use.

Thanks for the quick reply. I use this board and epaper lilygo epaper 7.5 with a code adopted from Waveshare. We use to have no problems but then since past one week we are having Buzy Timeout issues even for code that use to run fine earlier.

Library: GxEPD2 ver 1.4.5
Issue: When controller directs epaper to display. It doesn't and controller prints busy timeout on serial monitor
I have tried updating the library as well.
Please help.

This is a 4.7" e-paper display with a 4.7" panel with parallel interface. It is not supported by GxEPD2. As far as I know it uses a special library that directly drives the parallel interface by the ESP32. The library is available from LilyGo.

Thanks again. We use Waveshare Weather example (with one pin change in code) on the 7.5inch lillygo board and it was working for over a month. Now since past two weeks the Busy Timeout has appeared. Nothing else changed in the Waveshare example.

Then post a link to that 7.5inch board, and how you connected it.
A picture of your setup would be worth more than a thousand words.

Also post a link to the original code, I don't download from obscure places.
