FC 10 PIC 18 and FC 11 PIC 18 are also not working yet.

[Steve-Matrix]

To get v11 working with the PIC32, you probably need to replicate the "Build...Compiler Options" settings from v10.

I'm not sure how to get PIC18 devices working with CDC.

Hello,

FC 10 PIC 18 and FC 11 PIC 18 are also not working yet.

This is news to me, what specifically isn't working? Do you have examples or Forum topics where you are detailing the problems?

[SpeedPIC32]

Hello Benr,
I meant that the USB CDC for PIC 16 18 does not work with FC10 and 11.

Hello,

USB Serial works a treat on 8-bit PIC devices using v10 and v11. I've just tested it using our old ECIO hardware and it's working great.

The only thing you have to ensure is the clock speed which specifically needs to be at 48MHz.

I just tried v11 with the default "Compiler Options" settings and up-to-date library files and it compiles without error for me. It looks like your FCD file for the ECIO40 has been modified or your Compiler Settings are wrong because that device should override the compiler settings.

If it helps, my v11 project and compiler messages are attached.

Hello
I have got all versions in FC10 and FC11, with 8-bit and 32-bit PICs, USB CDC up and running.
Many thanks to everyone involved.
I had incorrect characters in the compiler settings, apparently 2 times ' ' instead of " it just looks the same. I had used copy and paste with a text programme and ended up with a space somewhere in the folder path and the wrong characters.
Thanks again
SpeedPIC32

Great news - thanks for letting us know.
