Naturally this code runs on the PIC16F877 of my project, which is wired up as described on in the #defines as well as the USB page. Below is a screenshot of HyperTerminal interacting with the system running this code.

For those having trouble getting started on their projects, here is a copy of a “Hello World!” program to test your RS232 serial link is working reliably. Then run, your PIC16F877 will blink an LED and print “Hello World!” once a second forever. text/html 2007-04-27T00:21:43+00:00 Anonymous (anonymous@undisclosed.example.com) http://www.robmeerman.co.uk/project/usb/code/hid-mouse?rev=1177633303&do=diff HID-Mouse This firmware enumerates the device as an HID-complient device, and then further 'enumerates' as a HID-Mouse (called “MeerMouse” ;-)). It doesn't appear to work on all machines though, as best I can tell it doesn't work on systems that do not have enhanced device drivers for the hubs loaded. It works fine on my laptop and my housemates machine, just doesn't like my dekstop as best I can tell. Ahh well. text/html 2007-04-27T00:21:44+00:00 Anonymous (anonymous@undisclosed.example.com) http://www.robmeerman.co.uk/project/usb/code/joystick?rev=1177633304&do=diff Joystick This is my near-complete code, I don't think I'll have any time to actually “finish” it, so I'll outline it's shortcomings here: * A HID-Class Get_Report request has never sent non-zero data in my experiments, but this may be because Get_Report and Set_Report were being issued at the same time
