Native USB host?

Projects Programming
1

Hello, a while back I tried to ask a question about Native USB host on a board like the esp32 so I can access a flash drive. I can’t see to find that topic and I’m working on a project that I need to complete soon.

My question is there is a library that will let me access a flash drive files over the esp32 native USB host. I can’t seem to find that library and I really need help from the community to find it again. Please help me community?

I will have other questions after I figure out the library.

This topic? Arduino USB drive?

This is a list of topics that you have started: https://forum.arduino.cc/u/josephchrzempiec/activity/topics

I can't answer your question about the library.

Hey @sterretje not that one. It’s one where you can plug a usb flash drive in the native usb of the esp32 and display files ona small screen or something.

Hey @sterretje thank you I saw the old one. I post update here since the old one is locked.

You can ask a moderator to unlock the old one. I can probably also do it if you post the link to the topic.
