Hi everyone.

I have to implement a USB HID device and I find the documentation a bit overwhelming!

My device needs to have three 'Write Reports' - each 6 Bytes long, and 1 'Read report' which is 3 bytes long. 

(Read and Write here as with repsect to the device, so a program on a PC can write to Report ID 1,2 or 3, and reads Report ID 1)

I have no idea how to set this up using the USBFS component! I am finding the documentation quite overwhelming, maybe because I don't know exactly where to start.

I have looked at the config section in USBFS component, and set the Product ID and Vendor ID etc in the 'Device Descriptor', and I have set the 'Configuration Descriptor' as best I can, but I'm not sure how to set up the rest of the interface descriptor to make it provide what I need!

Can anyone show me the basic steps here?

Many thanks! 

Hi WebSpinner,

Did you try reading the application note on USB HID?

It is available at http://www.cypress.com/?rID=39404

 Many thanks for that.

After reading the data sheet, and another one linked to from the first, I was able to get my prototype running :-)

Great going, WebSpinner !

 The attached project gives exactly what you need :-)

Just adjust the PID and VID values, and the manufacturuer strings to suit your particular device.

This one is for PSoC 3 however, so for PSoC5 you will need to adjust the Clock settings and use an external 24Mhz crystal.
