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...

Posted on July 18, 2016 at 19:39Hi, Got a weird enumeration issue on a USB device in my USB host implementation. Using STM32F746Discovery with CMSIS/HAL, re-utilising one of the provided USBHost library examples. I have a specific external USB devic...
Posted on June 29, 2016 at 03:30I've generated a test app using STM32Cube for a STM32F407 Discovery board and have been able to send and receive. I am now trying to port the code to run under microC/OS II. I have modified the ISR to include the uC...
Posted on July 16, 2016 at 21:37 Hi, I need to measure the time a PWM signal spends high. I have the input capture side of this working fine, but with IC mode set to both edges, there are occasional issues with the signal measurement. ...
