The USB topic

[Xamusk]

Indeed. I forgot to check if it was a C++0x extension. For that, I agree you really shouldn't use it in the demo, since C++0x is still incomplete in most (if not all) compilers.

Anyway, the code remains for those who want a more readable and simple way to write the descriptor strings. Should I repost the code to the Code Samples forum?

Good idea.

Here's my checklist for getting USB to work on STM32L151:

1) The port mode must be PIN_MODE_INPUT
2) The port speed must be configured as 40MHz (highest)
3) The port pull-ups must be disabled
4) The PLL output frequency must be 96MHz

Thanks for testing, I will add the note to the documentation.

Hi Giovanni
There is something broken in USB CDC code. I observe following error when trying to build testahl project for F1x.

build/obj/serial_usb.o: In function `getflags':
/mnt/work/projects/chibios/testhal/STM32F1xx/USB_CDC/../../../os/hal/src/serial_usb.c:107: undefined reference to `_ch_get_and_clear_flags_impl'
collect2: ld returned 1 exit status

Thanks, it is a consequence of the recent changes, fixed in trunk.

I know this thread was last replied to a year ago but I'd like to add the location of ST's vritual COM port driver:

http://www.st.com/web/catalog/tools/FM1 ... 3/PF257938

or: http://www.st.com/stonline/stappl/produ ... ctSelector
then Software > MCU Software > STM32 MCUs Software > STM32 Softw Dev Suites > Ctrl-F for Virtual

The reason I'm posting this is that ST revamped their site last week and pretty much every link in fora and blogs points to a 404 now.

regards,
Fred
