Touch screen USB for STM32F1 example

Question asked by feixas.bernat on Nov 9, 2015
Good morning,

I am trying to develop a touch screen screen controled by a STM32F1 and connected to a PC throught USB port.

My doubts are related with the USB comunication

I've found many examples for USB comunication as Virtual COM or as a Mouse/Joystic which works fine. But The problem is that a touch works in a diferent way of a mouse, I mean a mouse send frames with relative movement but a touch is absolute positions.

Anyone can give an example of a touch profile (HID) connected tot a PC?

Many thanks in advance
