Hi All,

This is a small project to develop a CDC+HID composite device class on PSoC3.
It uses an Interface Association Descriptor. This is needed, when two interfaces represent one functionality, in this case CDC.

These have been introduced in the application note: AN58726 PSoC 3/ PSoC 5LP USB HID Intermediate (with Keyboard and Composite Device), but has not been implemented in any project.

I hope you guys find it useful.

Enjoy!

This is very valuable for us, please make it a "real" application note with archive.

 

I noticed that I had to update  the size in the following declaration:

extern const uint8 CYCODE USBFS_1_DEVICE0_CONFIGURATION0_DESCR[121u];

in USBFS_1_pvt.h

Since this file is regenerated whenever I would change something basic on the schematic, I fear that I have to reapply this change again.
