STM32L USB Driver for Keil

Uli Behrenbeck

A good day to all,

does anybody know about an USB low level driver file for the Keil lib on STM32L chips?

Unfortunately Keil supports - up to now - only the F-Types in full and high speed.

The ones I find are:

usbd_STM32F103.c
usbd_STM32F10x_cl.c
usbd_STM32F2xx_FS.c
usbd_STM32F2xx_HS.c
usbd_STM32F4xx_FS.c
usbd_STM32F4xx_HS.c

thanks in advance,
Uli

    Thanks Tsuneo!

    I'm totally a newbie with microcontroller and currently trying to play with the USB function on STM32L-Discovery. I got stuck on how to port the STM USB library to the discovery board for a couple days and found your post a very helpful guide!

    I wonder if you used the licensed version of Keil toolchain? I downloaded your code and ran it with Keil, it showed the following error:

     .\Test.axf: Error: L9937E: RL-ARM is not allowed with this license

    Thanks a lot!
