History: usbd_drv_stm32

This page describes all changes made to the usbd_drv_stm32 package, USBD Low Level Driver for STM32, since its release.

Version

1.12:

• Compiler warning eliminated.

1.11:

• Supports STM32F0xx line.

1.10

•  Driver could crash in case host sent data before it could setup the next transfer. This is a problem using the driver with fast host controllers (handle_rx_ev() doesn't call copy_from_ep() when p_eph->tr == NULL).

1.9

• usbd_it_handler() defined as static and caused compiler error with GCC.
• Bug fix: endpoints were not initialized correctly.

1.8

• Memory corruption could occur at device disconnection (due to an issue in usbd_remove_ep()).

1.7

•  PSP interface changed.

1.6:

•  api_usbd_stm32.h created; contains API to detect missing SOF-s.

1.5:

•  config_usbd_stm32.c updated to work correctly with IAR.

1.4:

• Endpoint size configuration is fixed and located in config_usbd_stm32.c.
• ISO endpoint operation fixed.
• Driver worked incorrectly if the same endpoint used both (IN/OUT) directions.

1.3:

•  usbd_it_handler() prototype added to usbd_stm32.c

1.2:

•  usbd_stm32_it_info_lp, usbd_stm32_it_info_hp moved from PSP to usbd_stm32.c.

1.1:

•  add_ep(): buffer space allocation is now done automatically.
•  Function headers added.
•  Double-buffered endpoint buffer allocation fixed.

1.0:

• Initial revision.
