[Fx2lib-devel] fx1lib - cypress license issues

[Steve C. <nos...@ya...>]

Hi,

I would like to extend fx2lib to work with the original, full speed ezusb system. I have some cheap keyspan serial adapters to play with.

My question is has Cypress allowed the use of its header files? I don't know why they would not, but who can guess with lawyers? I found the cypress headers fixed by some kid in Spain, to work with the SDCC syntax instead of Keil. They still have the cypress copyright, but is that ok for using in fx2lib?

This fx.h file has been maybe manually converted like the fx2regs.h file in fx2lib. Is search and replace sufficient to establish a new copyright like claimed at the head of fx2regs.h? This whole licensing of basically names and a (fixed by hardware) address, is really stretching the definition of copyright. However, IANAL, so how has Ubixum decided on this?

The only questionable licensing issues are the few Cypress headers defining register names and possibly a header defining structures that match USB defined fields.

Regards, Steve
