Using HID to communicate pic 18F4550 with PC via USB?

[313230]

Dear all,

I tested the HID USB mouse which is plug-and-play. Is there any way to send data back to mCU using HID?

Regards.

for hid you have to write your own usb hid driver or use some one else.
see these links, first one for using usb hid class: Open Source Framework for USB Generic HID devices based on the PIC18F and Windows - WFFwiki

Hello,

There are examples using VB and Flowcode available from the Matrix Multimedia website. You can use your own compiler instead of Flowcode if you already have a working program. Its basically all in the HID descriptor which specifies how the data will flow. If you go to USB.org then there is a tool you can download with example descriptors.

If your host PC is windows then windows does expose ways of communicating with HID devices connected to usbhid.sys. I remember the native dll being usbhid.dll.
You might also want to take a look at the dll (CyUSB.dll) available through SuiteUSB 3.4 - USB Development tools for Visual Studio - Cypress Semiconductor .
