Compile error waveshare 7_5_T7

[kroon040]

Hi,

I tried to compile, and have a waveshare 7_5_T7, with esp32 driverboard. I changed to the right pins , but when compiling I get this error

You have multiple instances of the libraries, you will need to delete them from the sketch/ folder they should only be in the sketch/src/ folder

ok.

I did again open from the examples the ino file, with arduino. That I get the error. Or do I need the example to copy to the root folder??

found the issue. Dind not extract and compile the dir in the arduino lib dir.

You need to download the zip file from GitHub and use the IDE to add it using the zip option, then all the files will be placed in the correct location, at the moment your missing the font file.
