Question: where do the change from commit "Update USB configuration" come from and what are they fixing ?

ghost · 2017-09-04T13:03:07Z

@LMESTM

the change from commit "Update USB configuration" adapt the usb files from the previous commit (original source files from STM32Cube) for the Arduino project.

LMESTM

Few comments and questions but overall looks like a good PR - thanks for it !!

I guess it's ok, but why do you remove them ? can you explain in commit message ?

This removed only function parameters not used inside the function. There is no impact on the rest of the code but allow to remove some warning messages at compilation time.

Ok sorry - this is clear enough in the commit title already !

Does the change have an impact on the CPU or main peripheral clocks ?
Typically do we still have CPU running @ 80MHz ?

This modification do not impact the main clock. It's still running at 80MHz.

Can you be more verbose in the commit message concerning this fix ?
Does it only apply to this new board ?

Which compilation error does it fix ? And why is this visible only with this new board ?
Arduino.h is where wiring.h is included from and it first includes<chip.h> that should contain necessary defines.
Maybe the error should be corrected somewhere else ... depends on the actual error

It fixes a compilation error in the library SPBTLE-RF because we call wiring.h and without the fix it doesn't find some function of clock.h.
I tried to use Arduino.h but I had more compilation errors due to missing prototypes.
Maybe there is another solution that could be implemented in the library and not in the core. I will continue to look for.

Ok. I also think it is better to solve the library side and find the proper includes from the library

This include is missing in the core and is required.
Wiring.h declare a static function which use GetCurrentMicro() define in clock.h.
Already see this issue in my test_usb branch on my forked repo.

So I will leave it and we will use it as a fix.

OK @fpistm is the boss :-)

But I can be wrong...

Is LED4 definition really needed?

LED4 is defined to match with the documentation and the PCB serigraphy.

Yes I've saw it. one refers to WiFI and the other to BLE. depending of the gpio state.

In conclusion do we keep it?

Yes as the name is used.

Hi,
I have executed our test plan on this pull request. All tests are OK, good.

To reduce again the number of commits, a merge can be done with d24a022 and 3af2d2a
