Posted on July 27, 2016 at 17:24 Hi everybody, I try to make a bootloader with my STM32f091 to copy a new firmware to my boards using the Power Line Current. First, I bought the evaluation kit (STEVAL-IHP005V1), it works very without a...
Posted on July 27, 2016 at 11:50Hi!We're using ST USB Device Library. My question is about MaxPower field in device configuration descriptor.Let's assume that we have value 0xFA which means that we want 500mA from USB port. That's fine since host sh...
Posted on July 27, 2016 at 06:18 Hi all, I’ve been banging my head against an issue with FATFs and long file names. I’m writing a series of files to an SD card, and I’m composing the filenames from the date and time each file is created. The ...

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...
