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

    Hello!

    I'm trying to get my STM32L USB device to communicate with PC. Actually i'm stuck at just building the project files for Tsuneo's example HID project and I've come across a problem already.

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

    I have MDK-ARM Standard license. So, does that mean I can't use USB device if I dont have pro license? I don't use RTX (BTW: it is possible to use USBd without RTOS/RTX, right?)

    Thanks for answers.
