Hi, I am working with STM32F102CBT6. And I am going to use USB function of this MCU. Where can I find the suitable examples?

Best regards.

Hi David,

I'd highly recommend you to refer to 'USB Device' examples under

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-mcu-packages/stm32cubef1.html

. The examples are found under the path below:STM32Cube_FW_F1_V1.6.0\Projects\STM3210E_EVAL\Applications\USB_Device

Hi David,

• You may refer to the schematic used for our

  http://www.st.com/content/ccc/resource/technical/document/user_manual/0b/52/ea/f8/30/92/40/d4/CD00178166.pdf/files/CD00178166.pdf/jcr:content/translations/en.CD00178166.pdf

  (page34).
• Make sure to manage VBUS sensing if needed. Further information regarding this point are provided through this FAQ:
• To be compliant with the USB 2.0 full-speed electrical specification, do not forget to pull up the USB_DP pin with an 1.5kOhm resistor to a 3.0-to-3.6 V voltage range.
