Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Posted on July 27, 2016 at 08:40Hello all, I am a newbie in STM32 as well as CMSIS RTOS. We have selected STM32F429 as our controller. We need to make our entire application/drivers to be CMSIS compliant. As per our initial analysis, we found there...
Posted on July 25, 2016 at 22:32 Hi, I want to use the USB Host CDC. For this I use the HAL library and the middleware layer Here is my code: #include ''uart_USB.h'' #include ''usb_host.h'' #include ''usbh_core...

Posted on July 25, 2016 at 09:18Hi!We're using STM USB Device Library on STM32F429. I've been looking for this for two days but with no results. Is there any way to tell if the device has been enumerated? Preferably some callback after enumeration i...
Posted on July 19, 2016 at 06:13Started an example project generated by CubeMX and plugged the USB cable into the development PC. Please observe the following error. I think the report descriptor might be ill-formed: it's only 2 bytes, and ends wi...
Posted on July 22, 2016 at 22:58What ppm accuracy is needed for STM32F103RB as full-speed (12Mbits/s) device? Is RC HSI (a few percent error) not accurate enough for STM32F103RB as USB device? For STM32F401RE, do host or OTG modes require higher acc...
Posted on July 22, 2016 at 10:28Hi, since the WWDG of the STM32L0 series can be deactivated only by a hardware reset I don't understand the purpose of the function HAL_WWDG_DeInit in the HAL (v1.7.0). The function and its description suggest, that I...
