I made a 2.8 inch capacitive touch display with ESP32 S3. With USB capability of ESP32 S3, i figure to make a touch macro pad.
This macro pad is made out of a 2.8 inch touch screen, so touch is very responsive. You can launch a application, control volume, or other shortcuts.
I tried to control volume with a slider, which will make it more responsive. But currently i'm using USB HID protocol, which seem doesn't have exact volume value control.
There must be much more it can do, other than just some buttons. Maybe I will make an application on windows to communicate with it, to extend it's functionality, like showing CPU usage, temperature, RAM etc. and make more interractive controls.
Welcome to comment about how you feel about it and suggestion on how to upgrade the thing.
