STM32 USB Full Speed Device Library

It seems STM finally succeeded in their quest to make information about MCUs unsearchable. I can find a manuah for STM32 FS-Device development kit, but can anyone point me to the library itself (I need it with examples to write code for STM32F3-Discovery board)? I used google, I used navigation, parametric search (it sucks btw) and website search (it sucks even more).

If you are who reads this from STM, please don't take this as an offence, but as a mild and very polite feedback. You guys keep braking the links to stuff - almost any community howto on the web has broken links pointing to pages on www.st.com that do not exist. Great hardware, awful docs and zero respect to community efforts. #usb #stm32f3-discovery

This has F3 support code in it. V4.0.0 of the USB FS Firmware Library

Great, thanks, Clive!

*whispering to myself* But how one's supposed to know this????

I had to dig pretty hard to find this again. Ironically there are so many deep hard links to the site content because stuff is so hard to locate, or remember how to get too. I might edit some of my posts if I could find them, and if editing them didn't change the chronological order of the post/thread. Still the 404 error logs for the site must be massive. Hopefully someones tracking the metrics.

Hi! I'm very new to STM.

I would like to send some data from my STM32F0 to PC via USB. Can I use this library with STM32F0?

May be I lost the plot somewhere, but which F0 part supports USB? Perhaps you could use a CP2102, or some other USB-to-Serial chip?

hi clive1!

Do you know if this library is supposed to work with STM32F3-Discovery without modifications? I selected STM32303C-Eval configuration and it didn't work - I even managed to somehow damage the firmware in ST-Link debugger and had to reflash it with ST-Link utility.Or the library can work with F3, but examples have to be modified to fit hardware layout of F3-Discovery?Thanks!A.

For the most part examples published by ST target the EVAL series boards, porting them to the discovery series boards usually require removal of code related to the LCD, and perhaps changing pin assignments to suit the new target.

Spent some hours trying to trace the issue - no luck. It doesn't work, and it can't be debugged.

I love STM. That's why they call their boards ''Discovery''. Each time you manage to do something - it's like a big deal, whole-humanity concerning discovery. That's how much effort it takes.

I actually found that if I hold the USER button while I plug in user_usb cable, custom_HID demo works perfectly. If I release button however, the board immediatly stops responding. However long I look at the code, I can't find how this USER button relates to USB operation.
